Electric screwdriver connect from a car battery. Connecting an electric screwdriver to a car battery. Using a car battery
It should be noted at once that homemade improvements will reduce the mobility of the screwdriver due to the additional wire from the new power source and its mass. On the other hand, it increases the working time on a single charge up to 12-20 hours, compared to 2-3 with a native battery. It comes in handy on remote sites without power supply.
For convenience and safety, you should use a double-insulated flexible wire such as PVA and SHVVP. Cross section of 0.75 mm2 and larger. It can be connected in two places:
The molded case is split by a sharp blow with a screwdriver or split with a hacksaw blade at the soldering point. Then the old lead battery is removed and the power from the new source is connected to the freed wires, observing polarity.
How long does it take to charge the battery of an electric screwdriver?
Many people wonder how long it will take to recharge an electric screwdriver. The duration of this procedure depends largely on the type of charging used. For example, if the tool is connected to a pulse device, the process takes only an hour. During this time the electric screwdriver will be able to charge fully.
Some people use a regular non-pulsed charger. In such cases, the tool will take many times longer to charge. Charging will be over in 5 to 8 hours.
info! The duration of a full charge also depends on the model of electric screwdriver used.
Every such tool is sold with a manual. Read the manual before you charge the battery of your electric screwdriver. You can find more precise information about how long it takes to charge it in the instruction manual.
What the car owner needs to know
Important! If the battery of your car is not fully discharged, the additional power can provide a second battery. if you connect it in parallel, the voltage remains the same and the capacity will increase.
The solution to the problem
So, what to do if the battery is dead and can’t start the car engine? I went home and brought my cordless electric screwdriver to the parking lot:
- Removing the battery from the electric screwdriver.
- To the flat pins on the housing I wrap 2 thick screws with duct tape.
- Attaching the battery recharge wires to the resulting terminals.
- Observing the polarity, I connect both batteries in parallel (from the electric screwdriver and from the car).
- I leave the batteries on for 10 minutes.
- After 10 minutes, I try to start my car.

What the aFter needs to know is! 1. Cars use acid 12 volt batteries. 2. They are charged from the alternator while the engine is running. 3. Charging current 14,2-14,5 V. CURRENT IS MEASURED IN AMPS, VOLTAGE IN VOLTS. 4. Д.Б., don’t embarrass yourself!

What difference does it make what it is measured in? If you all know, why did not you offer this option and explain amperes and volts as in physics, we have a poor habit of not correcting in a mild way to try to be clever, I was lucky in life to meet in my life a man with three degrees in the parochial school received before the revolution, he was a man of great intelligence innovator an innovator of minds, making according to his drawings, where he himself reached all this science gathered around him skilled professionals from turners and other specialists to make such copying machines and tooling designers with higher education came to consult with him, he had already seen in the abstract whether it would work or not, and in the morning he suggested the right direction (this is an example)

This suggestion was written only for the sake of the publicity on the Internet. It is dangerous to let such a specialist near machinery if he confuses current and voltage.

I’m such an idiot. (electronica guy)!!) All my life I thought current was measured in AMPERS.
Not in Volts (Especially the charging current.).
Hattar, write again. Learn physics, bitch. And if you haven’t lived long enough to learn it, just kill yourself on the wall.

The article shows a complete ignorance of the author of both electrochemistry and basic electrical engineering. Yes, getting a little “shake” from the acum of an electric screwdriver starter will be able to crank and even start the engine. Then the charge will go according to the standard scheme. There are a lot of articles on the Internet on this topic, and I have seen with my own eyes something similar, but from modern special lithium batteries. But go further. the internal resistance starter is much lower than the resistance of the battery electric screwdriver, so, there is a high probability that he was just quietly “sitting” without saying his word. When starting the engine, the distribution of currents is not very clear, and one can simply “kill” the electric screwdriver battery.к. The starter’s starting current is pirmerno 100-300A depending on the volume of the engine and its power, the number of cylinders, oil temperature, ambient air and much more. Afftar is very lucky. Now about the capacity. well, do not know. do not write. The battery of an electric screwdriver at best 3 Ah, the starter has 50-60 Ah. Well, what is the increase then? BlurghFurther bloopers from Lyapis are disgusting to parse. But again, judging by publications inet variant has the right to life, but not with such explanations. Separately, I’d like to mention the acid-silica battery. Is this a new type of.

Laptop charger and car lamp
If the motorist has a laptop, he can use its power unit to “jump start” the dead car battery. You will also need an H4 headlight bulb (100 W/12 V). The parameters of the laptop charger are 19 volts, 4.74 amps.
The items to recharge the starter battery are recommended in the following order:
- First, connect the “plus” of the charger to the positive terminal of the battery.
- “Connect the minus pole of the charging cable from the laptop via the car lamp to the negative pole of the starter battery.
This technology will charge the battery in about 9 hours. At the same time, the car will start even at sub-zero ambient temperatures.
It is important to keep in mind that the lamp here is solving the problem of setting a specific current against a stable voltage of about 20 volts. The more powerful lamp will produce a higher current.
If you don’t use a light source, your laptop’s power supply might just burn out. This is because the battery has a minimum internal resistance while the charging current increases.
What else
Now for some important details. First of all, before you do anything with the screwdriver battery, you must first check its type. For our purposes nickel cadmium or nickel metal hydride batteries are fine. It is better not to experiment with lithium-polymer models because they may not be able to withstand the high current and explode.
Now for the charge. It is clear that the battery of a screwdriver must be charged, and at all 100%. If you try the trick with a half discharged battery, it definitely won’t work.
One last thing: even with a fully charged screwdriver battery, you can only start your car once. If you try to do it again, it will not work unless you recharge it again. Therefore, it is important not to stop the engine after it starts, to give the regular battery a chance to recharge.
How to start the car with an electric screwdriver
I should admit that the title of the article is not quite correct characterizes After all, the car engine will start not by the “screwdriver” and with the battery from it.
In the article, the author will dispel your doubts that the battery from under the electric screwdriver is too weak to rotate the engine of the car (even though it is a small car).
Disconnect the battery from the body of the electric screwdriver or portable drill.
Loosen the electrical contacts and screw the metal screws or bolts to them (as shown in the photo) for them will cling crocodile wires.
Now connect the battery of an electric screwdriver to a car battery. Observing polarity, the positive terminal of the battery to the positive terminal of the car battery and the negative terminal to the negative terminal.
Wait about 10 minutes to restore the auto battery.
In this way we can give the discharged battery some more charge to start the battery. Start the car battery only screwdriver battery, most likely, will not work.
There are a couple of nuances. The battery voltage must be the same or slightly higher than the battery voltage.
It is good if the battery of your construction tool will be well charged (over 80%). Universal power supply that charges not only smartphones, but also laptops and even a car battery. It has several outputs for different loads. To charge the car battery, there are separate wires, with “crocodiles”.
In the photo above Universal external battery Firefly MST-SOS2, which is designed to charge your smartphone and cigarette lighter car batteries. The laptop charger is simply not plugged in here.
But the most popular povibankom this class is Univesal povibank with the intricate name of “Wuhai”
The capacity of the above battery 12800 mAh, which reaches a full charge for 5-7 hours. Has a huge set of adapters and plugs for charging smartphones as well as laptops, tablets and other portable devices. It has 3 outputs of 5, 12, and 19 volts, with a power of 0.5, 2 и 3.5 amp. The total set consists of:
By the way, it is claimed that this device is able to “light” and crank the car gasoline and gas engines, up to 3.5 liters. What to do diesel engines and engines over 3.5 liters is not reported.
Note that with a long rotation of the starter, the battery of an electric screwdriver can overheat. The nickel cadmium batteries inside the battery can work well at subzero temperatures, which is not acceptable for lithium ion batteries.

Method 2
You need to open the hood and find the red thread on the coil. Both the cover and the coil on almost all engines are located on the back of the engine. In engines with four cylinders they are located on the right side near the center of the engine. In those with six cylinders on the opposite side: on the left, always near the center.
Remove the battery cables. Connect a cable from the positive pole of the battery to either of the positive poles of the coil or to the red wire connected to it. Thus, the dashboard receives power, a fundamental step in starting the engine.
Identify the starter solenoid. Unlock the steering wheel. Insert a flathead electric screwdriver into the center of the top of the steering column, pushing between the steering wheel and the column. The goal is to unlock the locking clips on the steering wheel. These clamps do not break or cause any problems, you need to find the solenoid, which should be directly underneath it.
Connect the solenoid to the positive pole of the battery. There will be a small wire at the top of the solenoid and under the positive battery cable. Remove the ignition switch wire from the solenoid and, using an insulated screwdriver, short the positive pole of the solenoid to the terminal to which the ignition switch was connected.
Is it possible to start the car from a laptop battery?
Usually takes 7-10 hours to fully charge a battery that is discharged to zero. If the battery is not fully discharged, 2 hours will be enough to start the machine. If there is no charger from a laptop, in principle it is possible to use the power unit from any computer.
It turns out, yes. The main thing is to start the engine and do not push the accelerator. then the alternator will feed itself and maintain some voltage in the onboard network. The “Behind the Wheel” magazine tested four ways to start a car without a battery. The first is to “light it up” by connecting a pair of jump leads to another battery.
How to start a car with a dead battery on the automatic machine?
First connect the plus side of the donor battery to the positive terminal of the car to be started, then connect the minus side. Yes, it is better to connect the minus on the starting car to the engine case. Start the donor’s engine and wait a few minutes so that the battery of your car can recharge a little. After a successful start we remove the wires.
Starting with a starter is the most popular method of starting a car without a starter among car enthusiasts. Another method to start the car if the starter does not work is to tow. You’ll need another auto and a rope for this one. If you have a breakdown on the road, just stop any car and ask for help to start.
Portable power supply from an electric screwdriver battery
Hi all.
To dilute my reviews, I’m adding a DIY post. Specifically a small case for an electric screwdriver battery which allows you to use the battery as a standalone 12V power source.
As a matter of fact, the idea came to my mind after I looked through the range of Miwaukee products. They have a Miwaukee Power Source. That is a case with a socket for connecting the battery M12. Planned to do this for a battery from BDCAT (review), but in fact it fits other Chinese batteries as well.
It took me a couple of days, the hardest part was the lock. Redrawed it 3 times until I hit the size (the Chinese apparently make standards “by eye”) Next I drew the case for the battery. The shape is a triangle and the battery has three 18650 cells. On the whole, it looks like this.
Loaded into the slicer for 3D printing, set up. Printed the default 0.2mm layer, about 2 hours. Better to print standing up, without supports. Fill at your discretion, 100% is not necessary, about 40%. 50% (wall is thin). Print result. For comparison, next to the battery I printed several cases at once, for experimentation. The battery case doesn’t fit tightly, with a slight stretch. The lock clicks into place, like an electric screwdriver. I made the contacts from a piece of tin (tin cans, beer cans, etc), that are not aluminum, can be made from a piece of wire) If you do it right, there is voltage on the pins. Label them for convenience and. The idea was originally for a TS100 soldering iron, 12V powered. In the photos saw the heating from 50 ° C to 250 ° C current consumption up to 2A Soldering iron works quite adequately. The battery has overdischarge protection, so it is safe to use. Additionally in the bottom there is a USB step-down (12V). 5V) In the bottom I made a place for the cable, but if you want you can finish drawing and the cover as the body of the board, for a particular version. You can charge your phone)))
Any connectors/outlets/cables can be furbished for convenience if desired. It is advisable to install a cigarette lighter socket, but this will increase the size of the Holder. Using Chinese batteries is convenient because they contain at once and the charging board with a round jack.
To the collider
The car had been stationary for a long time, and its old, factory battery gave up under the onslaught of frost. The central lock does not work, the dashboard does not light up, no relays are clicking. Engine. gasoline 1.6 with relatively fresh oil and new plugs. The first thing I did when I opened the hood was to measure the battery voltage, and it was only 2.5V: T.е. we have a completely and irrevocably dead battery, which should have been scrapped a long time ago. To be honest, at this point I got serious doubts about the advisability of further action, because this battery is almost equivalent to its absence, and to start the engine with just lithium alone is not possible: the maximum possible current output of my assembly is too low even for summer, and today outside.6°C. For safety reasons I took the battery out of the car, carried it to a safe distance and at gunpoint connected the lithium assembly to it. The voltage immediately dropped to 15.4B: To my surprise, there was no noticeable sparking or heating of the lithium banks, they became just barely warm. To be honest the measures I took were more of a “just in case” kind of insurance because lithium batteries in the form of 18650 and 26650 are relatively safe: they have a built-in membrane which in case of overpressure bleeds it into the atmosphere and breaks the contact. Meanwhile, the voltage began to slowly drop, a sign that the current in the circuit was flowing and the lithium was giving up its energy to the battery. I waited 10 minutes and put the battery and the connected to it (and the lithium was already cold) back in the car. Voltage was about 14 volts.9B: Connecting just the battery without lithium the car showed all signs of life: the central locking system started working and all other consumers. a sure sign that some of the energy in the battery settled. The moment of truth arrived.
I turned on ignition and listened to the gas pump. it was pumping and even seemed to be good, which was very encouraging. After the cutoff I turned the key, and. The starter started cranking the engine lazily but surely and the engine even caught but cut off right away. not enough rpm to have a full start. Tried again and it was the same and the battery-lithium pair had dropped to 14.2 volts. Worried about flooding the spark plugs I decided to give up and take the battery to the charger, but noticed a possible reason for the defeat: I forgot to turn off the “extra” consumers in the form of air conditioning and light. Although they shut off immediately at the moment of ignition, they still waste useful joules before it. Having turned off everything unnecessary, I decided to wait another 5 minutes and try for a rematch.
Rematch
During the wait the voltage rose and froze at 14.5В. Getting behind the wheel, I turned the ignition back on and waited for the gas pump to click. This time, the starter started more cheerfully and the engine grabbed with more confidence, but it felt like it was going to stall again. A little but in time gas made him reconsider his intentions, and HELLO: The engine successfully started, and I hurried to disconnect the lithium assembly. Outcome of the experiment: confirmed
I think many were greatly interested in the fate of the batteries in the assembly after the “mockery” performed on them. Residual voltage at the assembly. 15.1B: No traces on the battery terminals (except for those that were already there initially): Measurements showed that all batteries remained in working order, on all 26650 residual voltage. 3.75V, all 18650s are 3.85V, like a drugstore. Slight difference between the two types of banks was due to the higher capacity of 4×18650 than 2×26650. A sample test of several batteries showed that their capacity and internal resistance were also unaffected.
