Those who used a battery screwdriver - appreciated its convenience. At any time, not intimidated in the wires, you can bring to hard-to-reach niches. Until it is discharged.
This is the first drawback - needs regular recharging. Sooner or later cycles of reloading.
This is the second drawback. This moment comes the earlier, the cheaper your tool. Save money when buying, we most often get inexpensive Chinese "No-Name" devices.
There is nothing gallopped in it, but you should be aware of: the manufacturer saves the same way as you. Consequently, the most expensive block (and this is exactly the battery) when equipped will be the cheapest. As a result, we get a great tool with a good engine and a non-worn gearbox that does not work because of the poor-quality battery.
There is an option to purchase a new set of batteries, or replaced in a defective block. However, this is a budgetary event. The cost is comparable to purchase.
The second option is the use of a spare or old battery from the car (if you have it). But the starting battery has a lot of weight, and the use of such a tandem is not very comfortable.
IMPORTANT! Many screwdrivers have a working voltage of 16-19 volts. Even a fully charged automotive battery of such a voltage will provide. And we mean the use of b / y, where 10.5-11.5 volts can be on terminals.
There is a way out - alteration of the screwdriver in the network
Yes, one of the advantages of the battery tool is lost - mobility. But for work in premises with access to the network 220 volts is a great output. Especially since you give new life broken tool.
There are two concepts, how to make a networked screwdriver:
- External power supply. The idea is not so absurd, as it may seem. Even a major and heavy lowering rectifier can just stand near the outlet. You are equally tied to the power supply, and to a stuck network fork. And low-voltage cord can be made any length;
- Power supply in the hull from the battery. Mobility is saved, you are limited only to the power cable long. The only problem is how to squeeze a fairly powerful transformer into a small case. Questions about how the store is a compact screwdriver from the network - you can not specify. There initially installed motor 220 volts. Remember the Ohm law again, and we understand that a powerful electric motor for 220 volts can be compact.
IMPORTANT! Ohma law reads - with the same power, reducing the voltage - increase current strength!
Accordingly, the feeding cord by 12-19 volts should be with a large cross section than 220 volts.
Inexpensive screwdrivers for those who use the tool are not very often good. But, as practice shows, until time, until time. Most of them have batteries quite quickly, and sometimes they simply lack power. Solve this issue will help a simple version of the tool modification. At the exit you will receive a screwdriver that will work directly from car battery.
Materials
To modify the screwdriver with their own hands, prepare:
- screwdriver himself;
- long crusade screwdriver;
- file;
- clamps for battery with wires;
- nippers;
- soldering iron;
- solder;
- celebrate.
Step 1. Before you start work, you need to fully disassemble the tool. Use for this thin long screwdriver.
Step 2.. First, remove one half of the housing, and leave the second with its internal content in its original form. Remove the battery from the housing. Your screwdriver from the inside may look a little different. It all depends on the manufacturer. Be sure to find a positive and negative electrodes. For further work, you will be needed.
Remember the location of all internal details Tools and gently get them out of the case.
Step 3.. The bottom of the plastic case, which runs the function of the stand, boldly cut the file with the file. In a modified screwdriver, this part will be superfluous. Try to cut pieces symmetrically on two half tools.
Step 4.. The ends of the wires on the clips for the battery are cleaned. To do this, use a sharp knife. If you have too long wires, cut off the bruises and only after that, clean them.
Step 5.. Connect the wires to the electrodes. In this case, the design was a bit unusual, because it was enough to sell the wires in the clips and consolidate them with the help of the isol. In most cases, you will need to use a soldering iron with a solder. Be ready for this in advance.
Step 6.. Collect a screwdriver back. Insert the internal contents, wire with clips output. Collect the case and secure it with screws. At the bottom, where there was a stand, fasten everything with a tape by closing the resulting hole.

Despite the whole comic way, he really works. Only for chickens, we will not use the screwdriver itself, but only the battery from it. It is much smaller in size, not to mention the capacity and tension, but it is quite forces to start a car with a sewst battery.
You will need
- Battery from screwdriver with voltage 12 V and more, and better from 14 V.
- Standard wires for chinning with crocodiles.
- A pair of nails, screws or hexagon keys.
- Tape or.
- Dry sponge or rag.
How to start the car
If everything you need is at hand, you can proceed to the searction process. The procedure will be as follows:
1. Remove the battery with a screwdriver or drill, disconnecting it from the case.
2. Inspect the contacts. If they have an inner design, try inserting a nail, a screw or hex key to each of them. If they are made in the form of external connectors, then attach the same nails or self-tapping screws, and then secure them with a tape or tape.
3. Additional isolate improvised contacts from random touch, which can cause a short circuit, with a dry sponge, cloth or other item that does not conduct a current.
4. Connect the screws to the cigarette the battery screwdriver to, connect the positive contacts with positive, and negative with negative.
5. Wait about 10 minutes.
6. Try to start the engine confidently twisting the starter.
7. As soon as the engine earns, disconnect the wires to cure the car battery.
What else
Now about several important nuances. Firstly, before proceeding to any manipulations with a screwdriver battery, you first need to check its type. For our purposes, nickel-cadmium or nickel metal-hydride batteries are suitable. With lithium polymer models, it is better not to experiment, because they may not withstand high current and explode.
Now about charging. It is clear that the accumulator is screwdriver must be charged, and all 100%. If you try to check the trick with half a discharge battery, then nothing will come.
And the last moment: even from a fully charged accumulator, a screwdriver can be started with a car only once. If you try to do it again, then nothing happens until you recharge it again. Therefore, it is important not to join the engine after it starts to give a complete battery the ability to recharge yourself.
How can I do this? Isn't it dangerous for a screwdriver?
Because The operation of the screwdriver is associated with voltage shocks when you turn on and off, the car battery is suitable as it is impossible, because the normal operation of the latter is connected to the discharge-charge mode. Regarding the harm to the device itself (screwdriver), then there is no reason to fear - it will consume as much as he needs. True for good work screwdriver from the car battery. Its operating voltage should be around 12V.
You can connect a screwdriver to the battery using a flexible copper cable to the Plus Poles / Minus Poles on the device and battery, respectively.
You can connect the screwdriver to the car battery if they match the voltage, namely, the screwdriver will be labeled 12 V (such on sale is enough!), In this case, you can simply attach it to this time and work without fear.
But a large amount of screwdrivers have a higher voltage and 14V and 18V - in this case, for stable and high-quality operation, the screwdriver needs to use a rectifier with an adjustment of the voltage increase, otherwise the screwdriver will be given due to weak power, and the ampero of the battery will heat it - what can lead to a breakdown of an electrical appliance.
Rule more often we are dealing with 12-14 volts screwdrivers. This is the most optimal voltage and is quite suitable, so it is quite suitable for connecting a screwdriver to the automotive battery. Here the main thing is not to confuse the polarity minus plus. Even if your 18 volt screwdriver is not trouble. It can also be powered, just power will fall a little. But it is not scary, it is a screwdriver, not a turning drill. Your work will make such a screwdriver normally.
If the risker is designed for a voltage of 12 volts, then it is natural that it can be connected to the car battery and not only. It will also be a battery from the uninterruptible, it is also descended for 12 volts. He is not confused by the plus and minus terminals for connecting the shurthold A diode into a break of one wire. This is simply theoretically should help from improper inclusion.
