Can I Use a Car Battery to Charge a Screwdriver

It often happens that repairs occur suddenly when something goes wrong by accident. In this case, you need to have at hand everything you need in order to urgently eliminate the breakdown.

Among the most commonly used construction tools, both professional and household, a screwdriver should be highlighted. Due to the continuous improvement of technology, modern screwdrivers do not work from the mains, but from batteries mounted directly in the tool itself. There are situations when the battery charge is at zero, and you need to urgently charge a screwdriver.

With the help of such a screwdriver it is possible to perform work in almost any conditions, at any height, regardless of whether there is electricity nearby. In addition, with this tool you can perform a wide range of construction work, and not just screw or unscrew the screws. Knowing how to charge a screwdriver in any situation, even without having a battery pack, you can always keep the tool in working condition.

Types of Screwdriver Batteries

Before purchasing new batteries for the device, thoroughly study the instructions that came with it again. There are different categories of tools that differ from each other in their characteristics: household, semi-professional, professional. Depending on the type of device, battery chargers for it also change.

Any of these batteries is designed for a certain type of work, and accordingly, for different types of loads, so each of them requires a separate charge. The duration of the screwdriver will depend on the power of the battery, so the higher it is, the longer the device will work. Nevertheless, it is recommended that you always have a spare battery with you, which in unforeseen cases can replace the previous one.

Usually, when you buy a new screwdriver, a spare battery comes with the kit. Returning directly to the types of batteries, it is necessary to note the most frequently used of them: lithium-ion, nickel-metal hydride and nickel-cadmium.

Nickel-cadmium (Ni-Cd). the most commonly used, and accordingly, the most common types of charges, which are distinguished by their compactness, reasonable price and high energy intensity.

With proper charging, proper operation and, of course, the purity of the materials used in the battery, such devices can be charged more than 1000 times. However, there are some conditions that must be observed in order for the battery capacity to last for a long time.

First of all, you need to wait until the battery is completely discharged, since such batteries have the so-called memory effect. Without waiting for a complete discharge, the capacity of the energy carrier gradually begins to decrease, leading to a decrease in the duration of operation. In addition, the toxicity of nickel-cadmium batteries should be noted, so you need to be very careful when using them. In no case should you drop and hit such energy.

Nickel-metal hydride (Ni-MH) are the next in the ranking of the most popular batteries. They represent a modern generation of devices based on the latest technology. These types of batteries from an environmental point of view are absolutely safe. In addition, they are very easy to dispose of, that is, these energy sources are safe for both humans and the environment.

The pluses of nickel-metal hydride batteries include a mild memory effect. This means that you don’t have to worry about the charging frequency. It is necessary to store them in non-operational time in a charged state. If the interruption is more than 30 days, then it is necessary to completely discharge the battery.

Lithium-ion (Li-Ion). recently, they began to use more powerful batteries, which are based on lithium-ion active substances. They do not have a memory effect, which allows them to be charged at any convenient time, without waiting for a complete discharge. In such energy carriers there is a large energy intensity, which is enough for several working stages.

Lithium-ion batteries are exposed to the negative effects of low temperatures, so working with them in the winter is not recommended.

This type of battery is not yet very popular due to the fact that the price is very high.

How to charge a screwdriver: some nuances

There are several features of accumulative chargers that must be taken into account when charging in order for the screwdriver to last longer. Using the example of a lithium-ion screwdriver, the principle of charging the device can be explained.

Before first use, you need to fully charge the battery, since during storage until sale, the power gradually decreases. In order to maximize the battery capacity, it is necessary to charge the device 3 times, each time after that discharging it to zero.

After that, the battery power will become maximum, thereby ensuring a long period of use. Energy sources such as lithium-ion batteries do not need to be fully discharged, so they can be charged to maximum immediately. For optimal charging conditions, it is also recommended that the ambient temperature be considered. According to the instructions for use, the temperature dispersion for optimal operation is 10-40 ° C.

Additional terms and tips

Device charging time

As for the charging time of the energy carrier, then usually all this is indicated in the instructions attached to the device. It is highly recommended that you comply with all operating and charging requirements specified by the manufacturer. This will help preserve the charge capacity for a long time.

Modern chargers have a special indicator that shows the level of charge. Such an indication system makes it easy to determine at what level the battery charge is. In addition, you must know that immediately after a full charge, you must disconnect the device from the station in order to avoid damage.

Depending on the type of battery, charging can take from 1 to 7 hours. So, for example, the nickel-cadmium type charges up to 7 hours. The current is supported by the network adapter if it exceeds the norm of 250 mA.

How to store the device?

It is necessary to pay special attention to this item, since repairs do not occur every day and, accordingly, a screwdriver is not required daily. Therefore, the following procedures should be performed before storage:

  1. Nickel-cadmium. it is recommended to discharge such batteries to a state where the device will work at a reduced pace, but not to zero. During long-term storage, it is advisable to completely discharge the device, and then charge it to half. This energy intensity is enough for slow discharge during long-term storage.
  2. Nickel-metal hydride. such batteries are recommended to be stored in a charged state due to their increased charge. If this type of battery is not used for a long time, it is advisable to leave it to charge for 1 day before use. It should also be noted that the charging capacity begins to decrease only after 200-300 charges, so do not worry about the loss of capacity during storage.
  3. Lithium-ion are the most picky types of batteries that, as previously described, lack a memory effect.

Thus, many factors must be taken into account when recharging batteries so that they last as long as possible.

Screwdriver battery device

The battery is an energy source for cordless screwdriver models. Due to the occurrence of physicochemical processes (electrolysis), this element accumulates electricity, and then produces a constant voltage of the desired value at its respective outputs. Voltage and capacitance are the main parameters of any drive. The first shows the potential difference between the cathode and the anode of the battery. Voltage is measured in volts. The capacity determines the amount of current issued by the battery for 1 hour, therefore this parameter is measured in ampere-hours.

For different models, the battery pack (battery) looks and is designed in a similar way. It consists of the following structural elements:

Is it possible to charge a screwdriver with a car battery

Not all models are equipped with thermistors. The case is usually a two-piece plastic box. He basically has about 10 batteries inside, and sometimes there are more. In this case, the batteries are connected to each other in a chain. The free terminals of the extreme cans are connected to the contacts located on the housing, designed to power the electric motor of the instrument and connect to the charging equipment. Battery output voltage determined by summing this parameter of all batteries connected into a single circuit.

There are 4 contacts on the battery case:

  • 2 power ("", "-"), designed for charging and discharging;
  • one control top connected to a thermistor;
  • one contact used for charging from special stations that are able to equalize the charge value of all the batteries available in the unit.

By type of batteries rechargeable drives are divided into the following types:

  • nickel metal hydride (designated NiMh) with an output voltage of 1.2 V;
  • nickel-cadmium (labeled NiCd) output also give 1.2 V;
  • lithium-ion (denoted by Li-Ion symbols), in which the voltage depends on the number of power elements in the battery and can be in the range of 1.2-3.6 V.

Lithium-ion batteries have a control board. At the same time, a special controller monitors the operation of batteries.

A separate battery consists of the following structural elements:

  • positive and negative contacts;
  • positive charge electrode;
  • external cover of the body;
  • electrolyte;
  • negative electrode.

Nickel-cadmium energy storage devices are most widely used due to the affordable price, compact size and large capacity. They can be recharged more than 1 thousand times.

General battery charging rules

In order to properly charge the screwdriver battery, a certain external battery must be provided. temperature condition. The optimal temperature is from 10 to 40 degrees. An undesirable point is a possible overheating of the battery pack during charge accumulation. To avoid possible negative consequences of this phenomenon, it is necessary to disconnect the battery for cooling from the charger.

It is not recommended that after the batteries have reached full capacity, left in a disconnected charger or inserted into a screwdriver, which will then not be used, it is better to put them in a case from under the tool.

Battery packs that are not used for a long period of time are recommended to be recharged once a month.

The recommended battery charging time is from 30 minutes to 7 hours and depends on its type. For a specific model of power tool, it is indicated in the operating instructions. These instructions must be followed exactly so that the product lasts a long time. Most Chargers equipped with indicators, showing at what stage the process is. In such cases, by lighting up LEDs of a certain color, it is not difficult to determine how much batteries need to be charged. After reaching the full capacity level, you must immediately stop the process.

The nuances of charging various types of batteries

Charging various types of battery packs has its own characteristics. They are related to the properties of the materials of which the batteries are made. For regular recharging of battery packs, pulsed or conventional chargers are used. Adapters of the first type are equipped with professional power tools, and the second. models for domestic use. New or discharged drives during storage must be properly charged before use, taking into account their characteristics.

So, nickel cadmium batteries different pronounced "memory effect". The first time it is recommended to charge them three times in a row, each time at the same time completely discharging. Only in this way will the maximum (working) value of the battery capacity of the drive be achieved. After that, you need to conduct a regular connection of the screwdriver to the charger when its power drops to a minimum.

At nickel metal hydride batteries there is also a “memory effect." Before the first use, it is recommended to repeat the full charge / discharge cycle for them 4-5 times. With further use, the charge is replenished as necessary.

If the initial charging of the nickel-cadmium and nickel-metal hydride batteries is not performed correctly, then the capacity of their batteries will gradually decrease.

Lithium battery packs least whimsical. There are no special rules for them, because there is no “memory effect". Lithium-ion nutrients can maintain their initial levels of working capacity for a long time. Each time it is not necessary to bring them to full charge / discharge.

Charging methods without using a special charger

When a standard charger is missing or simply broken, you can do without it. Craftsmen came up with different ways to recharge the battery from different sources. To charge the battery of a screwdriver without a conventional charger, you can use:

  • car charging;
  • universal type charger;
  • external sources of electricity.

The best option for car charging is a device with the ability to control the magnitude of the voltage and current. The main thing in such cases is to avoid overcharging. For this, the charging current is set so that the process goes from 0.5 to 0.1 A h, depending on the size of the total capacity. For example, if it is 1.3 A h, then the current should be from 650 to 130 mA.

When the current values ​​are too large, and the regulator cannot set lower values, additional resistance is used, for example, a car lamp. It is connected in series to the battery pack.

Universal charging convenient in practice. They have many additional settings that allow you to optimally select the appropriate current parameters for recharging batteries from various power tools.

External power sources They are mainly used for worn screwdrivers, for whom it is not economically feasible to purchase new batteries. In such cases, the power tool is upgraded in a certain way, and an appropriate connection diagram is developed. An example is a redesigned USB charge, additionally equipped with a fuse.

Battery Storage Recommendations

It is recommended to store any type of battery by disconnecting it from the screwdriver. Each type of battery also has its own characteristics in this regard:

  • Nickel-cadmium batteries must be discharged before storage to such an extent that the screwdriver does not work at its full capacity;
  • Nickel-metal hydride batteries are recommended to be kept fully charged, but their small discharge is still allowed;
  • Before storing a lithium-ion battery, it also needs to be discharged, but only half.

After a long storage period nickel metal hydride batteries, capable of withstanding 200 to 300 recharge cycles without loss of capacity, it is necessary to recharge within 24 hours. Blocks of this type are distinguished by a significant self-discharge parameter.

As mentioned above, lithium ion power cells deprived of the "memory effect". They have a large capacity and the lowest self-discharge rate. You can recharge their charge at any time, despite the degree of discharge.

Do not completely discharge Li-Ion batteries, because this may cause the built-in electronic protection system to turn off against rising temperatures or voltages.

In order to achieve 50% of the charge required for proper storage, lithium-ion batteries need to be charged from almost zero level for a period of about 65% of the time it takes to reach full capacity.

Compliance with the simplest recommendations on the storage and charging of various types of battery packs will make it possible to develop the entire resource of batteries inherent in them by manufacturers.

Checking the battery status with a multimeter

Not always, when the battery runs out quickly or does not function at all, you need to buy a new one or carry the unit to the service center specialists. In many cases even an inexperienced electrician will be able to find the cause of the malfunction independently, having familiarized himself with the search algorithm. To do this, you will need to use a multimeter or instruments similar to it in measuring capabilities. In addition to this device, you will also need the following tools:

  • screwdriver;
  • soldering iron with a set for soldering;
  • knife;
  • pliers.

In order to accurately determine the cause of the battery malfunction, it is necessary to find out the performance of each individual power supply. But first recommended check charger. With a multimeter, this is done in this way:

  • turn on the device;
  • set the switch of the measured values ​​of the multimeter to a constant voltage;
  • install the probes in the corresponding sockets of the multimeter and touch them to the contacts ("" and "-") of the charger;
  • compare the value displayed on the instrument panel with the output voltage of the charger specified in the operating instructions or on the case;
  • if the values ​​do not match, then repair the adapter or buy a new one.

Whenever possible, the measurement range that is closest to the output voltage indicated on the charger is selected on the device used.

To check screwdriver battery multimeter, perform the following steps:

  • fully charge the battery pack;
  • check the output voltage of the battery with a multimeter by setting the device switch to its constant value, and touch the plus and minus with the probes;
  • if the discrepancy of the measured parameter to the value specified in the operating instructions is established, then the battery pack is disassembled and all batteries are removed;
  • when there are no damaged banks (leaked or swollen), then check the voltage at the terminals of each battery with a multimeter, first using a soldering iron to solder the circuit;
  • the load is connected to the batteries in turn for the same time (for example, a lamp of the corresponding voltage);
  • on which battery the greatest drawdown occurred, it is damaged.

For testing, nickel-metal hydride and nickel-cadmium energy storage devices are completely discharged. this is done in order to avoid the "memory effect".

When checking batteries, it should be noted that for nickel-cadmium and nickel-metal hydride types of batteries, the output voltage should be in the range from 1.2 to 1.4 V, and for lithium ones from 3.6 to 3.8 V.

If you find a defective battery, you can replace it with a new one or try to temporarily restore it by adding distilled water or exposure to high voltage. You can also use a multimeter measure current: if it grows and in the first hour exceeds 1 A, then the battery is considered operational.

If there is no voltage at the output of the battery, then there is a high probability of breaking the integrity of the circuit inside the unit. At the same time, they also disassemble the block and first search visually, and then with the help of a multimeter, the place of the cliff.

Before using the new cordless screwdriver, you must carefully study the instructions for use of this product supplied by the manufacturer. The features of the type of batteries installed on the power tool should be taken into account in order to properly charge them and also to store them for a long time. Compliance with simple recommendations will extend the battery life to a complete exhaustion of the resource. When there is no branded charger, then the alternative charging methods mentioned above will temporarily help.

If the battery capacity drops, the operating time on a single charge decreases, you can repair them with your own hands. To do this, it is enough to set the output current or voltage with a multimeter and compare their compliance with the standard values ​​of these parameters.

Proper charging of a screwdriver: how to do better

There are a few simple rules on how to charge a screwdriver’s battery so that the tool uses its full potential.

If your screwdriver has lithium-ion batteries, it is not necessary to carry out such “pumping” because they do not have a “memory effect”: these are more modern batteries.

It is necessary to charge the battery at a favorable ambient temperature. The best temperature indicators at which the screwdriver battery should be charged are not lower than 10 ° С and not higher than 40 ° С. During charging, do not leave the battery unattended for a long time to avoid overheating and overcharging. Although, if the regular charging of the instrument is equipped with an indicator for monitoring the entire process, the device will automatically “finish” it when it is needed.

It is not recommended to leave the battery pack in the charger for a long time. And if the screwdriver is not used so often, it is better to remove the batteries from it and store it separately from it. In the case when the batteries are left without use for a long time, make sure that they are in a charged state, conducting them "Recharge" once a month for 25-30 minutes.

As you know, a cordless screwdriver power supply can be either nickel-cadmium or lithium-ion. Ni Cd batteries can be stored at any charge level. Their main advantage is that they are not afraid of deep discharges. In order for them to work well after a long break, they should be “pumped” as usual three to four times. The "pumping" time, on average, is 3-4 hours, during which you can work with a screwdriver in normal mode. It is advisable to control during the operation of the screwdriver that the Ni Cd battery is not discharged partially, but completely. This will help her not accumulate the very same “memory effect”.

If your instrument’s battery pack is not equipped with nickel-cadmium batteries, but with lithium-ion batteries, their main “plus” is that They have no “effect" of memory. However, it is recommended to monitor their charge level more carefully. If a screwdriver with lithium batteries is not used for some time, they need to be recharged periodically. They just do not like deep discharge. If the lithium batteries are deeply discharged, the protective controller will operate inside the battery pack. To prevent this from happening, make sure that the batteries are charged at least 50 percent.

How long does it take to charge a screwdriver battery

Each power tool is always accompanied by an operating manual that accurately indicates how long it takes to charge the battery of a screwdriver. As already mentioned, the vast majority of modern chargers have charge level indicators, which greatly facilitates their use. When the indicator lights up in green, or in another color, indicating that the charging time of the screwdriver’s battery is approaching the end, you need to disconnect the battery in time.

The average time during which the battery is fully charged is 7 o’clock. And if the battery just needs to be recharged, it can be left on charge for 30 minutes. Although, in the case of Ni Cd batteries with a "memory effect", frequent and short recharges are not recommended.

There are several types of chargers for a screwdriver, depending on the scope of their application. Ordinary memory, As a rule, it is included in the package of household power tools. Battery charging time with it varies three to seven hours. There are still powerful impulse-type chargers, which are equipped with professional tools. How much to charge a screwdriver battery with such a device? "Impulses" can fully charge the battery In one hour, which is their undeniable advantage. However, the cost of such an instrument, of course, is much higher.

What to do if the battery does not charge or does not hold a charge

In this case, there are few options: either the cause of the malfunction lies in the charger, or the screwdriver itself “jams”. Also, the battery pack may eventually run out of life and need to be replaced. In order to find out the reason, it is necessary to carefully examine both the tool itself and its battery together with the charger.

Often the reason for poor battery charging is that the contact between the screwdriver and its charger weakens due to extension of the terminals. To fix this problem, it will be enough just to disassemble the charger and carefully bend its terminals back.

Do not forget about such a frequent malfunction as the oxidation of the metal parts of the battery itself and the charger. The constant ingress of building dust and dirt also contributes to a weak charge current from the charger to the battery: instruments charge less. It is important not to forget to take care of all the components of the tool in order to prevent deterioration of its work by wiping the metal contacts and cleaning them from contamination.

If the battery itself has run down, you can try to “swing” it, as is usually done in the case of nickel-cadmium cells. If this does not help, you will either have to change the battery pack completely, or partially replace its elements.

About screwdriver battery repair →

Usually, any screwdriver is equipped with two identical batteries. If one of them fails, if desired, you can collect one working battery from two, in case the capacity has become less in both. After one working one is assembled from two blocks, you need to remember to equalize the capacitance of the elements by “pumping” the battery with several “charge-discharge” cycles for 3-4 hours.

You can also try to “cheer up” the batteries individually. To do this, the weakest of them should be charged with high currents, then assemble the battery back and charge already in normal mode. This method sometimes works with nickel-cadmium batteries. "Point" recharging with large currents should last no more than 3-5 seconds, however, it is advisable not to allow severe overheating of the element in order to avoid its destruction.

Custom methods for charging a screwdriver battery

It also happens that the “native” charger from a power tool is either lost or malfunctioning, and acquiring the same is very problematic. Many people ask whether it is possible to properly charge the battery by connecting it to some other power source.

Of course, this can be done. And such charging methods will not do any harm to the battery, if you familiarize yourself with the characteristics of the instrument itself and any other charger, which can serve as an alternative power source for the battery.

In order to find a suitable alternative charger for your screwdriver, you need to know the indicators of its voltage and capacity. They are usually indicated on the outer casing of the instrument. You should also pay attention to the polarity. It may be different, depending on the manufacturer. This is very important for properly connecting the battery to the charger.

Which charger is suitable is determined as follows. For example, we have an 18-volt screwdriver with a battery capacity of 2 A / h. This means that the charger should be able to produce the same voltage, and the power will be enough 200 milliamps per hour. since it takes a long time to fully charge such a battery. It is better to use a charger with the ability to regulate the current, charging the battery 6-7 hours.

To supply current to the battery, you can use crocodiles of small sizes. And so that the contact is good, they can be additionally fixed with metal wires.

If possible, try charging the screwdriver battery with a car charger. It is important to remember that in this case the voltage should be set to the very minimum. Determine the polarity of the battery and the car charger (as already mentioned, it can be different). Then connect the terminals from the car charger directly to the battery. Sometimes, for optimal contact, you also have to use additional “fasteners” in the form of paper clips or flexible metal plates.

After such simple manipulations, it remains only to turn on the device in the network and carefully monitor the charging process. For starters, it’s enough 15-20 minutes, and when heat transfer will increase in a charged screwdriver battery, the charger should be disconnected.

Recently, it has become very popular to replace batteries in a screwdriver from cadmium to lithium, especially among professional craftsmen who use a screwdriver regularly. The battery charging time in this case will also depend on the type of charger. If you have a regular “standard” charger, the battery can charge from 3 to 7 hours. And if there is an opportunity to purchase a modern pulse charger, it will be enough hours with a little in order to bring the battery into working condition.

Additional terms and tips

Before using the battery for the first time, it is advisable to charge it, as the battery may run out during storage.

  1. Do not allow the battery to overheat, as high temperatures negatively affect charging performance. In this regard, it is desirable to cool the battery during overheating.
  2. It is not recommended to leave the battery in the charger.
  3. It is advisable to remove the battery from the screwdriver after use and store it separately.
  4. In case of prolonged non-use it is recommended to recharge the battery once a month.
  5. After first use, the battery must not be completely discharged. An indicator that the charging ends is the reduced speed of the screwdriver.
  6. Properly operate the device. follow all points of the instructions for use.

Device charging time

If a nickel-cadmium battery is used on a screwdriver, then for its maximum operation three times charging is required.

As for the charging time of the energy carrier, then usually all this is indicated in the instructions attached to the device. It is highly recommended that you comply with all operating and charging requirements specified by the manufacturer. This will help preserve the charge capacity for a long time.

  3. Lithium-ion are the most picky types of batteries that, as previously described, lack a memory effect. You can charge and discharge them at almost any time. The only thing that is not recommended to do is to bring the energy source to a complete discharge. This can lead to a shutdown of the protective system and a decrease in battery capacity. In such energy carriers there is electronics, which protects the device from overheating and overvoltage. The number of charges does not affect the capacity, however, such batteries are operated in full operation for no more than 2 years. After this period, charge performance is not guaranteed.

Thus, many factors must be taken into account when recharging batteries so that they last as long as possible.

A screwdriver is one of the most popular tools. It is noteworthy that with the help of a screwdriver you can not only screw and unscrew the screws, but also drill holes. A screwdriver is good for everyone, however, the use of an electric tool creates inconveniences of a certain nature. the network is not everywhere, which interferes with work, and the cord can interfere with an effective workflow. In this regard, cordless screwdrivers are becoming increasingly popular, since they do not have the above problems. You can work with such tools anywhere, you do not need to look for a place where there is an outlet.

One of the main elements of such a screwdriver is the battery, thanks to which the tool is able to function offline. But with all its advantages, there are also disadvantages associated with how to charge the battery.

Rechargeable batteries

Before you start charging the battery of a screwdriver, you must purchase new batteries. Still need to carefully read the instructions for the device. Batteries are different, the differences are in capacity, price and quality.

It is best to give preference to the most powerful batteries that can work for a long time. Experts recommend purchasing 2 batteries at once, then when one of them works, it is possible to charge another. Often, 2 batteries are included in a set.

Among various batteries, nickel-cadmium and nickel-metal hydride, as well as lithium-ion, are the most popular. As for the 1st type of chargers, they are large in size, capacity and quite affordable prices. Charging can be carried out efficiently at least 1000 times. But here it all depends on the features of the design, the operating mode and on how correctly charging is carried out. The second type of charger is good in that it is absolutely safe from an environmental point of view. As for lithium-ion batteries, they are good for everyone, but very poorly tolerate low temperatures. This does not allow you to work with them in frosty weather. Despite the fact that they are charged very quickly, the capacity is high and it is easy to work with them, they are not very popular so far. the prices are too high.

In order for the charger to work longer and not break, it is very important to properly charge the battery.

Before using charging for the first time, the battery must be charged, as it tends to discharge during storage. In order for the screwdriver to work with maximum efficiency, it is recommended that you first charge it 3 times before work, after which it is discharged. The fact is that the capacity of the new battery is incomplete. It is necessary to make it fill. After that, the battery needs to be charged as soon as the power becomes minimal.

If we talk about lithium-ion batteries, then using them is much easier. There is no memory effect there, which makes it possible not to bring them to a complete discharge, and you can charge this type of battery when it is required. For proper charging, it is necessary to take into account the optimal mode of the working process. It is strongly recommended that the ambient temperature be between 10-40 ° C. It should be borne in mind that during such a process, batteries can become very hot, but this should not be allowed. The fact is that overheating of the chargers adversely affects the quality of work, so it is necessary to cool it from time to time. As for the battery, leaving it in the charger is strongly discouraged. It is best to carry out its storage separately, it must be disconnected from the screwdriver. If it is not intended to use a screwdriver for a long time, then recharging should be done about 1 time per month.

As for the purchase of batteries, it is recommended that preference be given to those sold at specialized points of sale. We must not forget that only proper operation can significantly extend the life of such a device.

The answer to this question can be obtained in the instructions that come with the kit. The information indicated there should be studied very carefully. Often, the charger is equipped with a special display system, so you can easily understand how the charging process is progressing. It is very important to interrupt charging in time, otherwise the battery can easily be damaged. If we talk about the specific timing of charging a screwdriver, then they directly depend on the type of device, but on average it may take from 30 minutes to 7 hours. Charging current can be supported by a network adapter.

Table of battery characteristics for a screwdriver.

For the battery, you can use 2 types of chargers. impulsive and ordinary. If we talk about a standard charger, then it is most often used among non-professionals, on average 3-7 hours are enough to charge the battery. An impulsive charger is more suitable for a professional movement. Using it, you can expect that the battery will be charged in just 60 minutes.

Many people wonder if it is necessary to charge the battery if it has not been used for a long time. Nickel-cadmium batteries must be discharged before storage, but do not bring to zero. It is necessary to bring to such a state that the device can work, but not at full strength. After long-term storage, before using the device, it is necessary to fully charge and discharge it 3-4 times.

It is strongly recommended that nickel-metal hydride batteries be stored in a charged state, and after they have not been used for a long time, the charging process should be carried out for at least 24 hours. If we talk about lithium-ion batteries, it is recommended that they be stored in such a way that they are approximately 50% charged.

If this situation is observed, then there may be several reasons:

  1. Worn out.
  2. Malfunction.
  3. Disruption of contact between the battery and charger terminals (correcting the situation is not difficult here: you just need to disassemble the charger and bend its terminals).

The cause of the malfunction may be that the contacts of such a device can be oxidized and contaminated. Malfunctions in the system may consist in the fact that the charging time is significantly reduced, as well as the duration of the work afterwards. To prevent such problems, clean the battery terminals regularly.

The more closely the battery monitoring is carried out, the longer can be expected. Thus, the question of how to charge the battery cannot be called particularly difficult.

How to charge a screwdriver battery correctly

A screwdriver is perhaps the most common tool of a home master, because it is with its help that you can drill, screw / unscrew hardware, and even perform grinding operations (when using special equipment). It is also encouraging that a screwdriver can perform all of these operations without being connected to the network, thereby providing mobility and convenience for the operator.

However, the flip side of the coin is the rapid wear of the power battery pack, which, incidentally, is one of the most expensive components and thanks to which the screwdriver is able to solve all technological problems. Therefore, in order to extend the life cycle of the battery, it is advisable to understand how to charge the battery of a screwdriver and what features you should pay attention to when performing this operation, first of all.

We recommend that you familiarize yourself with the detailed methodology for restoring batteries for a screwdriver in this article.

Screwdriver Battery Types

In order to properly charge the battery for a screwdriver, first of all, it is necessary to clarify its type and technical characteristics: voltage level, capacity, design. And if the technical criteria of the battery can be found on the battery label, then the type of device can be determined based on their marking:

Ni-Cd. nickel-cadmium batteries, have excellent consumer properties: small overall dimensions, small cost, high capacity, which is why they are most often used for power tools. However, a significant limitation of the presented elements is the “memory effect”, which consists in the fact that untimely recharging of the battery (at the moment when it is not completely discharged) can lead to a multiple decrease in its capacity. In other words, nickel-cadmium batteries should not be charged until fully discharged. In addition, the components of the elements presented are toxic, which is why they should be disposed of only through special companies.

Li-Ion. lithium-ion batteries have also recently gained great popularity among manufacturers of power tools, because unlike the previous version, such cells do not have a “memory effect”, and at the same time they have a high charge speed and excellent capacity. If we talk about the shortcomings of lithium-ion batteries, we should highlight their somewhat overpriced cost and the inability to function at low ambient temperatures (the battery capacity instantly drops).

Ni-MH. nickel-metal hydride batteries boast environmental friendliness and lack of memory effect, but at the same time, these batteries are inferior to their counterparts in all technical indicators, which is why they are rarely used as power elements for stand-alone power tools. In addition, a significant limitation for nickel-metal hydride batteries is a high degree of self-discharge, due to which even a working battery in standby mode can lose its capacity in less than a month, which negatively affects the performance of the cell as a whole. In view of this, even if a nickel-metal hydride battery is not used, it needs to be recharged periodically.

How to charge the battery for a screwdriver

Of course, before charging the battery of a screwdriver, it is advisable to familiarize yourself with the accompanying documentation for the tool in order to subsequently perform all the work in accordance with the manufacturer’s recommendations. In addition, considering the features of charging for batteries of any type, the following should be highlighted:

  • Charge the batteries only at a positive ambient temperature (above 5 ° C);
  • After the recharging process, the battery should be removed from the device and the battery should be stored separately from the instrument (in order to exclude self-discharge and contact oxidation);
  • Monitoring the battery charge should be done according to the indication of the charger, or otherwise controlled, as shown in the instructions.

If we talk about the charging method for various types of batteries, then it is necessary to highlight the following.

When purchasing a screwdriver equipped with a nickel-cadmium battery, you should not immediately put it into operation using the base charge of the battery. A more justified action would be the initial recharging of the battery to the maximum, followed by a threefold cycle of discharge. charge. And after that you can operate the tool. over, taking into account the “memory effect”, it is necessary to discharge and charge the nickel-cadmium battery to boundary values ​​(minimum and maximum).

When it is necessary to create conditions for long-term storage of the battery without work, then the optimal state for nickel-cadmium batteries in this case will be half the charge. Whereas if it is necessary to use, the battery which is in a semi-discharged state will first need to be charged to the maximum, and only then connected to work. over, from one storage stage to the next, the battery should experience at least five charge-discharge cycles.

If we consider the features of charging lithium-ion batteries, then everything is much simpler and the main thing that needs to be done after acquiring a tool is to completely discharge the battery. And to begin the subsequent operation after its full charge. And although, unlike the previous version, such batteries do not have a memory effect (that is, they can undergo charging / discharging at any time), still the stability and durability of the devices depend on the capacity here. In view of this, the lithium-ion battery should be kept in a recharged state (the battery capacity should be at least 50%), and in the case of long-term storage. recharge the battery at least once every 60 days. Subject to basic recommendations, the total life of lithium-ion batteries can be extended up to 2.5. 3 years.

Nickel metal hydride batteries are less optimized for the consumer. Indeed, given their main drawback. fast self-discharge, leaving such batteries without recharging for a long time (more than 1 month) is an inadmissible luxury. Indeed, without a charge, such batteries are destroyed and become unusable very quickly. In addition, nickel-metal hydride batteries are limited by the number of charges. discharges and require replacement or restoration after 300 cycles.

However, in any case, you must take into account the recommendations on the operation of the tool, which you can find here.

What to do if the battery does not charge

Sometimes there are situations when the battery for a screwdriver is not charging, so it is advisable for the user to know what nuances should be paid in this case.

The first thing you should pay attention to is the quality of the contact plates (both on the charger and on the battery). Indeed, given the wide scope of application, this site may be susceptible to oxidation. Repair in this case does not cause difficulties and comes down to wiping the contact groups with the help of specialized compounds, as well as ensuring a tight contact contact (the antennae are bent inwards).

Screwdriver Battery. How to Charge

It would seem that charging a battery for a screwdriver is a simple process. Just insert the battery into the standard device, and wait for the green to turn on instead of the red LED. Then we take out the battery, and you can work. And there are no problems in the work of the screwdriver. it still works, and it also successfully tightens and unscrews self-tapping screws, screws, screws. But let’s take a closer look at how a screwdriver battery works. How to charge the battery correctly? You just need to understand what its principle of action is based on.

Differences in the types of batteries (batteries) screwdrivers

The battery is a chemical power source. It consists of several elements of a certain type. In budget screwdrivers, nickel-cadmium elements are used, sometimes nickel-metal-hydrite, in expensive ones, lithium-ion, or lithium-polymer. They are designated, respectively, Ni-Cd, Ni-MH, Li-ion, Li-Po. The cells in the battery are connected in series. Each of the elements in a charged state produces a fixed potential difference. Connected in series, these elements together give the operating voltage of the battery. Each of the series-connected ones gives the potential difference with the neighboring one, and the two extreme ones. in total, the working voltage value. You can read more about batteries on Wikipedia:

When the battery is being charged, the electrons sequentially penetrate the batteries and restore the chemical solution. In the process of work, as well as storage, the substance is oxidized, and the electrons again turn into a neutral state, simultaneously performing useful work. This is called a charge-discharge cycle. Until the end, discharge does not occur anyway, and some potential difference remains. This is called residual stress. The battery is based on electrolytic dissociation processes.

Battery Charging Cycle

Charging the battery is a complex electrochemical process. The simplest models of chargers charge the battery in sequence. This means that electrons pass in turn through all the elements. over, in extreme batteries, the process of dissociation will be more complete, but in medium batteries it will not go through to the end. Charging will also take much longer. advanced chargers charge each cell in the battery separately. In this case, charging lasts several times faster, and all the elements in the battery are charged approximately the same, the process of dissociation in them goes almost to the end.

The first method of charging has a certain drawback. Elements in the middle of the circuit are not fully charged, and eventually begin to lose their properties. Battery replacement may be required. Therefore, if you have the opportunity, leave such a battery turned on for charging at night, but nothing more. During the night, all the elements will be charged.

For batteries of all types, there is such a thing as a memory effect.

That is why it is recommended to discharge the batteries to the end.

Screwdriver Charger Indicators

What does the lit green LED show? In most cases, it shows that some electric charge current still passes through the battery. When the potential difference of the battery is equal to the voltage of the charger, the current stops and the green light comes on. When the charging current is still flowing through the battery, the red light is on. complex models of chargers have a special electronic control system that monitors not only the charging current, but also the potential difference of each element and the magnitude of the charging current.

Screwdriver Battery Storage

How to store batteries in a charged or discharged state? For nickel-based batteries, it is best to fully discharge, and for lithium-based batteries, approximately half charge. Half of the charge will be achieved by about 2/3 of the time from normal charging, when the battery is fully discharged and then recharged to the end again. Since lithium batteries are usually bundled with an expensive device, here you can consider a full charge the moment the green light comes on.
