Modern devices for recharging equipment with electricity are equipped with an energy indicator. Unplug the power supply immediately after the green light turns on, indicating charging is complete. The minimum time required for this process is half an hour. It may be increased depending on the type of battery. The longest recharge time is with the nickel cadmium type battery. It takes about 7 hours to fully enrich such a cell with electricity.

The instructions for your Bosch electric screwdriver give you a more precise battery charging time. There you will also find a detailed description of the process for your battery model. When using the equipment, it is worth following the annotation in full. This will extend the life of both the device and the power source. Therefore, before you charge a Bosch electric screwdriver battery for the first time, it is advisable to read the instructions carefully.

How long does it take to fully charge

How long does it take to charge a screwdriver battery?? It should be specified for what purpose is being charged. Manufacturers tend to speed up the charging time, to reduce interruptions and increase competitiveness. That is why the maximum permissible charging current is set. Often a 10 to 20% capacity is sacrificed at the end of the charging cycle.

This can be seen in the lithium battery charge graph. Where for the first hour of charging it recovers 70 % of capacity, for the second hour. another 20 %, which makes 90 %, and for the last 10 % it takes 1 hour more, all in all 3 hours. And the regular charger “Bosch” from China charges a lithium battery in just 30 minutes. With these subtleties in mind, it is now possible to answer the question posed.

It is sufficient to charge the battery once to operate the tool. If necessary, it is not necessary to wait for the end of the charging time, and after half the standard charging time you can start working. Undercharging of batteries in single cases does not have any negative consequences.

Maximum battery charge is required for training cycles and even more so for restoring battery capacity. How do you do this with the battery charger if it is automatically switched off?? After voltage stabilization, after 20-30 minutes you may continue charging the battery on the regular charger again. It will take up another amount of energy. It is a good idea to charge the battery up to three times. So the battery will be charged almost 100%. This is important in order to use the entire volume of the electrolyte in the subsequent training cycle.

New Ni-Cd and Ni-MH cells are charged with the standard charger in 1 to 8 hours, according to different manufacturer’s data sheets. This variation in time is caused by different settings of the charging current, depending on the manufacturer’s position on this issue. In addition, even chargers from the same manufacturer can have a range of up to 2 hours due to setting errors, because in the final stage of charging current decreases extremely slowly. And the minimum current will always be.

Tip! In the process of long term exploitation of a screwdriver the actual capacity decreases. It is useful to measure the charging time of new batteries after training cycles and write it down on the case. Comparing with the subsequent charge time in a year or two you can see how much capacity the battery has lost.

New lithium (Li) batteries can be charged in 30 minutes to 120. This also depends on the charger settings of each manufacturer.

How to know when an electric screwdriver battery is charged?

Some models have a light indication. it will indicate when the unit is fully charged. Disconnect the battery from the charger immediately after charging is complete. Typical charge times from half an hour to 7 hours, depending on battery type and charger.

Green and Red. Green light is on when the charger is plugged in. The red light is on when the battery is connected to it, which means that the battery is in the process of being charged. Once the battery is charged, the charger shuts off.

How to charge a lithium ion battery properly?

The process of charging the Li-ion battery itself is not difficult. you must first connect it to the regular device for charging, and then connect the device to the mains. Once fully charged, simply disconnect the battery from the charger.

Minimum time needed for this process is half an hour. This may be increased depending on the type of battery. The longest recharge time is with the nickel-cadmium type. It takes about 7 hours to fully enrich such an element with electricity.

How much to charge the battery of a Bosch 18v electric screwdriver?

The average time in which the battery is fully charged is 7 hours. And if you just need to recharge the battery, you can leave it on charge for 30 minutes. Although, in the case of Ni Cd batteries that have a “memory effect”, frequent and short recharging is not recommended.

The basic principle: install a voltmeter on the battery terminals with charging. If within one hour the voltage does not increase with the charging current, which does not change, it means that the battery is 100% charged.

Before you buy a new battery for your electric screwdriver, you should carefully read the instructions for the tool. The tools you need for the job can be professional, household, and semi-professional. their batteries differ in capacity, quality and price.

Certain types of cordless tools are also designed for certain jobs, designed for different loads, so they require different batteries. The higher the power rating of the battery, the longer it can last. For convenience, it is better to have two batteries so that you can recharge the second battery when working with one. Often a second battery is included with the tool when it is sold.

Different types of batteries can be used for screwdrivers. The most frequently used batteries are nickel-cadmium (Ni-Cd) and nickel-metal hydride (Ni-MH), and lately lithium-ion (Li-Ion) batteries as well.

The most common of them are nickel-cadmium batteries, characterized by their compact size, high capacity and reasonable price. These batteries can be effectively charged over a thousand times, depending on their design, cleanliness of materials, mode of operation, including the correct charge. However, these devices have a so-called memory effect, and if you charge them before they are fully discharged, the battery capacity will gradually decrease. over, the production of such cells is so toxic that the European Union abandoned it in its territory.

In second place in terms of frequency of use are nickel-metal hydride batteries, representing the new generation of such devices. From an environmental point of view, both the production and disposal of these batteries is practically safe. The pluses of this type of batteries include the fact that they have a less pronounced memory effect, and the minuses are. a high self-discharge current. These batteries must be kept charged and must be fully recharged if not used for more than a month.

Not so long ago for cordless tools began to use a more powerful lithium-ion batteries. They also do not have the disadvantage of the memory effect, which requires periodic discharge cycles to restore the capacity. However, these batteries do not tolerate low temperatures, and it is undesirable to work with them in freezing temperatures. Despite the fast charge and high capacity, they are not very popular yet, because their price is quite high.

What to do if the battery of an electric screwdriver does not charge?

If the electric screwdriver battery fails to charge, it could be because the battery is worn out or the battery charger is faulty. However, it is often the contact between the battery terminals of an electric screwdriver and the charger that is the problem, as they unravel over time. In this case, you can disassemble the battery charger and bend its terminals.

In addition, after some time of use, both battery and charger contacts can become oxidized and dirty. Even small changes of this kind can interfere with normal battery charging. This usually translates into a significant decrease in both the charging time and the operating time of the cordless power tool itself. To prevent this from happening, you should periodically wipe the contacts of the battery, battery charger for the electric screwdriver battery and the tool.

Unfortunately, battery cells degrade over time. Thus, if improperly used nickel-cadmium batteries, most often used in domestic models of screwdrivers, they quickly lose capacity. Experts sometimes recommend “overcharging” such batteries. The battery pack is disassembled, and the problematic elements are identified. After that you need to charge them. What current to charge the battery of an electric screwdriver in this case? Experts recommend first charging such cells with a higher current than they should be charged, then discharging them and then charging them again, but with a lower current. If the electrolyte has not yet evaporated in the Ni-Cd batteries, such “therapy” may help bring them back to life.

In addition, it is possible to restore one battery pack from two that have partially lost capacity by selecting from them and soldering together the whole “banks”. After that, in order to equalize the charge, it is required to fully charge and discharge the restored unit several times.

Also the reason that the battery is not charging may be in the temperature sensor
