Battery selection

The main parameter that needs to be taken into account is the supply voltage indicated in the passport or on the case. The motors used in screwdrivers also operate at reduced voltage, losing somewhat in speed and torque. The most affordable of the batteries will be acid for cars, motorcycles, as well as for uninterruptible power supplies.

How to power a screwdriver from a third-party battery

The service life of a screwdriver is 5–7 years, and its battery life is at best 2 years. This means that by replacing the power source, it will be possible to extend the life of the beloved instrument by at least 2 years. Of course, it is best to find an original battery, but the problem is its availability and cost.

How to replace the battery for a screwdriver

It should be noted right away that the handicraft modifications will reduce the screwdriver’s mobility due to the additional wire from the new power source and its weight. On the other hand, the operating time on a single charge will increase to 12–20 hours, versus 2–3 with a native battery. This will be very useful in remote sites without power supply.

For convenience and safety, double-insulated flexible wire such as PVA and ShVVP should be used. Section 0.75 mm 2 and more. You can connect it in two places:

  • to the screwdriver handle;
  • to the body of the old battery.

The cast body is cracked with a sharp blow to the screwdriver, or it is separated by a hacksaw blade at the soldering point. Then the old lead battery is removed, and power from a new source is connected to the free wires, observing the polarity.

Gel (batteries for UPS)

Their advantage is a sealed body and a paste-like electrolyte, which allow the instrument to be used in any spatial position. It is possible to use a charger from a screwdriver. Here you can not be afraid of acid burns or spoiled clothes. You can attach the battery directly to a screwdriver or carry it in a bag or s.

Automotive

The question often arises whether it is possible to connect a screwdriver to a car battery. Indeed, you can use a battery that has worked out its resource, the capacity of which is already small for a car, but sufficient for a hand tool. The standard voltage of car batteries is 12 volts.

In view of the mass of 14 kilograms, it is advisable to use such source at a stationary workplace, scaffolding or mobile platforms. The length of the wire is 2-3 meters. Charging will have to be done by a third-party device due to the high charging current.

Motorcycle

They differ in mass in the range of 2-4 kilograms. Voltage 6 and 12 volts.

Precautions

It should be borne in mind that connecting a new power supply is an interference with the factory design. This means that it is important to pay attention to personal and fire safety. Remember that you need to:

  • observe polarity;
  • securely insulate wire connections;
  • use chargers rated for the capacity of this battery.

A minimal knowledge of electrical engineering is sufficient to replace the battery. Locksmith skills will also come in handy. It is necessary to provide increased mechanical strength of the wire connection points.

Connecting to the power supply from a computer

These PSUs are distinguished by the presence of their own cooling system, protection against voltage surges. Only two output wires are used for connection, yellow. 12 volts “plus”, black ground.

The disadvantage of this option is that the power supplies must be worn during work and installed in a well-ventilated place.

It is possible to attach a handle for mobility. It is important to understand that cordless screwdrivers with a required voltage of more than 14.4 volts will not work from this method of supplying energy.

DIY screwdriver alteration

There are enough craftsmen in everyday life of the household, there are many ways how to convert a screwdriver to mains power. It is enough to provide the required voltage for the electric drive of the device.

Disassembled cordless screwdriver

In some cases, for alteration, it is enough to use the charger from the kit, it is available, because supplied complete with a screwdriver. It is quite simple to remake such a structure, it is enough to disassemble the screwdriver, connect the output contacts on the charger with the drive wires. The voltage produced by the charger after the alteration corresponds to the technical characteristics of the drive, there is no need to worry about the safety of the electrical part. It is also worth noting that there is no need to disassemble the device completely. only the wires designated for use need to be connected. A significant drawback is the size of the charger, it is not convenient to constantly move it during work and causes discomfort.

The power supply of the screwdriver can be achieved by several types of blocks. The case accommodates some of them, the rest are outside.

There are many ways to alter a cordless screwdriver, all have pros and cons.

  • In the case of the old battery, a place is organized for the finished power supply unit. The alteration is simple, no intervention in the electrical circuit is required, it is enough to carefully perform the work, to achieve a perfect appearance. The disadvantages are the time spent looking for a block with the appropriate voltage and size. Also, small devices usually heat up in an enclosed space, it is necessary to provide the device with ventilation by making holes in the case.
  • Installing a homemade energy source is a more complex solution, it requires finding the necessary radio parts and understanding the circuit. The advantages of this method of alteration are low financial costs, no losses when using a low voltage cable, no changes in the appearance of the device.
  • An external power supply unit can be used when working in one place, since the device’s mobility and compactness are lost. There are also costs associated with finding a suitable voltage for the electric drive of the screwdriver.
  • The most common external type device is a computer power supply. The advantages are that it is easy to find it on disassembly for a reasonable price, there are no complicated rework processes. However, the bulky design will not be to everyone’s taste.

How to power a screwdriver while maintaining its autonomy

There are situations when you have to work in the absence of electricity. Powering a screwdriver without a 220 network is possible in several available ways. In such cases, if the battery of the device is faulty, and alteration from the mains is impossible, there are several ways to activate the wrench:

  • Replace the battery cells inside the battery with new ones purchased from radio parts.
  • Using an external rechargeable power source such as a UPS battery.
  • Connected and powered by car battery.

It is important to remember that any alteration requires technical skills and safety.

Homemade power supply

When working with a soldering iron, it is necessary to check the connection to the network of the battery cells and the self-made unit, if there is a connection, all power sources must be disconnected for safe operation.

Alteration work is carried out step by step, to obtain the result you need a little experience when soldering and installing boards:

  • Dismantling and dismantling the old battery case;
  • In accordance with the diagram, install the elements on the circuit board, solder the contacts and connections.
  • After soldering, check the output voltage with a multimeter.
  • Assemble the board to the battery case.
  • Connect appropriate wires to the instrument’s low voltage outputs.
  • Check operation by connecting the converted device to the network.

Mounting the finished power supply in the old battery case

If it was possible to purchase a power supply unit with the corresponding indicators on the market, installation and alteration is carried out in several simple steps:

  • Dismantle the old battery housing, remove the spent elements.
  • Install a new power supply in such a way that it fits snugly against the case, if necessary, you can glue it, connect high voltage wires (output from a 220 volt outlet).
  • Connect the low voltage terminals to the power supply of the electric motor of the wrench, in the absence of contacts, the wires will have to be re-soldered.
  • Assemble the body after alteration and install the unit on the screwdriver.

Mounting the finished power supply in the old battery case

It must be remembered that compact power supplies are heated in an enclosed space, therefore several holes must be drilled on different sides of the case for ventilation.

Connecting to an external power supply

The external battery is used when compact elements are inaccessible or the need for continuous operation of the tool.

Cordless screwdriver connected to an external power supply

It is worth remembering the steps during disassembly or taking pictures, since intervention and alteration of the electric circuit of the screwdriver are performed, the assembly will need to be done exactly in the reverse order.

Connecting to car battery

Connecting to a car battery will make it possible to work autonomously without a power supply. The parameters of the screwdriver can be from 10.8 to 14.4 volts, a charged car battery is capable of delivering an average of 12.5 volts of voltage. To use, you need to connect two power wires with crocodiles to the screwdriver.

Connecting to car battery

The alteration is carried out after the disassembly operation, then connecting the power wires to the wires of the electric drive of the screwdriver. In the absence of a soldering iron, it is possible to simply connect with a twist, but this does not guarantee reliable contact. After connecting the contacts, isolate the wires and test the tool during operation by connecting to the battery.

How to remake a cordless screwdriver

The cordless screwdriver is used everywhere, both in the household and in small industries. Mobility and autonomy allow you to perform work away from the electrical network for a certain time. The battery has a certain number of charge cycles, after which it is not suitable for further use. There are several reasons, the battery is a very capricious element that breaks down even if not properly stored and inactive. The high price of a screwdriver prompts you to learn how to convert a cordless screwdriver into a network.

How to connect a screwdriver to a car battery

Inexpensive screwdrivers for those who do not use the tool very often are good. But, as practice shows, for the time being, for the time being. For most of them, the batteries fail quickly enough, and sometimes they simply do not have enough power. A simple modification of the tool will help to solve this issue. At the end you will receive a screwdriver that will work directly from the car battery.

To modify a screwdriver with your own hands, prepare:

  • the screwdriver itself;
  • a long Phillips screwdriver;
  • file;
  • battery clamps with wires;
  • nippers;
  • knife;
  • soldering iron;
  • solder;
  • duct tape.

Step 1. Before starting work, you need to completely disassemble the tool. Use a thin, long screwdriver for this.

Step 2. First, remove one half of the case, and leave the other with its internal contents in its original form. Remove the battery from the case. Your screwdriver may look slightly different from the inside. It all depends on the manufacturer. Be sure to find the positive and negative electrodes. For further work, they will be needed.

Note the location of all internal parts of the instrument and carefully remove them from the body.

Step 3. Feel free to cut the lower part of the plastic case, which serves as a stand, with a file. In a modified screwdriver, this part will be superfluous. Try to cut the pieces symmetrically on the two halves of the tool.

Step 4. Strip the ends of the wires on the battery clips. To do this, use a sharp knife. If your wires are too long, cut off the excess parts with wire cutters and only then strip them.

Step 5. Connect the wires to the electrodes. In this case, the design was a little unusual, so it was enough to thread the wires into the clamps and fix them with electrical tape. In most cases, you will need to use a soldering iron to connect. Be prepared for this in advance.

Step 6. Assemble the screwdriver back. Insert the inner contents, lead the wires with the clips out. Assemble the case and secure it with screws. In the lower part, where the stand was, secure everything with electrical tape, covering the hole with it.

The result of your efforts will be a significantly improved screwdriver with a performance higher than before. At the same time, you can use it while on the road or far from places where you can charge the battery of the instrument itself.

Is it possible to connect a screwdriver to a car battery

Is it possible to connect a 12V 2A screwdriver to a 12V 60A car battery, what is needed for this?

The fact that 60 amperes or more is written on the battery is not as important as the voltage of 12 volts, this is what you need to be guided by.

If the screwdriver is 12 volts, and not 9 or 18, then there will be no problems.

The only thing that is advisable all the same is to connect the circuit to the elementary, most unpretentious (fusible) fuse with the power declared on the screwdriver, namely in our case it is 2 amperes in order to secure the electrical appliance, because the battery power is quite enough to warm up and remove it from building the electric motor of the device.

Then everything is simple, you need to unscrew the handle of the device, determine the polarity of the /. input and connect them to the battery terminals, put the positive wire through the fuse.

For the connection, it is best to use terminals with bolt clamps, or solder the wires with a soldering iron.

Further, everything is as usual, the standard controls of the screwdriver will perform their functions, and if you use a cable of sufficient length, then the connected battery will not create obstacles for comfortable work.

DIY automotive screwdriver

Drills and screwdrivers are the most essential tools for repair work. They are used for drilling holes, twisting and unscrewing screws, self-tapping screws, screws. As part of this article, we will modernize an old standard screwdriver into a car one powered by a vehicle battery.

Homemade automotive screwdriver from a standard

The old standard screwdriver has completely sat down nickel batteries, there is no point in buying new ones, because it is easier to buy a new one. And so that the old screwdriver could be used, I decided to connect it to a car battery. Agree, you do a lot of work in the immediate vicinity of your vehicle. It remains only to make small changes to the typical design of the screwdriver.

For modernization, we need the following parts or products:

old screwdriver long screwdriver for a cross file about 2 meters wire wire cutters or a sharp knife soldering iron with soldering accessories

Let’s start by disassembling your old tool with a Phillips screwdriver. Carefully separate the upper part of the case and put it aside for now. And put the other part straight in front of you. In the handle we can see two electrodes, B (positive) and B- (negative). The old battery must be removed.

Symmetrically cut off the lower part of the case with a file. It is not needed in a car screwdriver. To connect the power tool to the battery, we take installation wires with a small cross-sectional diameter, from two or more meters in length. Attach crocodile connectors to the free ends of the wire. I recommend connecting the opposite ends of the wire to the electrode terminals. Be sure to observe the polarity when connecting! Wrap the joint with electrical tape. Now you can assemble the device in reverse order. Place the insides into the body of the tool, lead the wires with the clips out. Fold the two halves together and tighten with the screws. Cover the part that we sawed off a little earlier with electrical tape, securing the resulting structure.

As a result, you get an excellent screwdriver that will serve you for many years.

How to connect to the charging station

Before deciding whether it is possible to charge the battery of a screwdriver with a charger, you need to remember that the charging unit of the screwdriver supplies a low voltage, with a long wire length, the voltage is lost, so it would be rational to connect through a meter cord with a cross section of 2.5 mm2 or more.

connecting, screwdriver, battery
  • Wires are attached to the contacts of the charging unit of the screwdriver. Spoiled nutrients are removed from the nest.
  • A groove is made in the case, a cable is passed through it. It is proposed to seal the entry point with elastic material so that there is no backlash and the wire is held securely in place.
  • Since the nest has lost its weight after removing the unusable elements, it is recommended to restore the balance by inserting some kind of load into the vacated space, otherwise the hand will get very tired during work, eventually harming the health of joints and ligaments.
  • The cable and previously attached wires are connected together, the body is assembled.

Car charger

In search of a solution to the question “is it possible to connect a screwdriver to a charger”, you can stop at charging with a car AK-block. Modules with manually adjustable current, voltage are applicable. The connection is absolutely not complicated. it is enough to connect the input channels of the tool motor to the contacts of the car charger.

Block inside

The solution to the problem “is it possible to connect a screwdriver through a charger” can be an alternative way to power the screwdriver. installing the power supply into the empty case of the power supply unit of the tool.

Before starting the action, it is necessary to prevent overheating of the unit, for which holes are arranged in the case in advance, which will provide air movement, heat removal. It is advisable to reduce the time of continuous work with a screwdriver with such an improvement to 15 minutes.

A ready-made block is purchased, it is selected according to the size of the case, technical indicators. The most suitable for use is the pulse version of the module, it is small in size, lightweight. The use of modules of domestic production from the times of the last century is not recommended. they have large volumes with low efficiency.

Unsuitable batteries are removed from the bed, and the power supply is placed in their place. The contacts are energized, the case is closed. The assembled hybrid gadget is ready to work from the network.

  • Cables can be extended for convenience.
  • It is necessary to monitor the quality of the assembly: the structure should not be able to touch the metal elements, otherwise the circuit cannot be avoided. It is best to leave some space between the transformer and the board, which will have a positive effect on cooling.
  • If any parts of the structure are very hot, it is possible to install modules that remove excess heat, or to arrange ventilation slots.

Other ways to supply power

A computer module will work too

Another solution to the problem of powering a screwdriver. mounting it to a computer power supply. This option is applicable to those modules that are equipped with a mechanical trigger. The positive aspect is that the unit is cooled by a cooler and is protected from exaggeration of the load by the built-in special system.

Such an assembly is arranged only with the use of power modules for 300-350 W and a current of 12 volts, at least 16 A. For instruments with a voltage of more than 14 volts, this power supply option does not work.

The user may want to hide an unaesthetic unit in a beautiful case, then it is recommended not to forget to arrange ventilation in it.

On their own

For users with special knowledge and skills, there will be no difficult problem “is it possible to power a screwdriver from a charger without special means”, because assembly of the feeding block is possible with your own hands. Instead of damaged elements, a power module assembled according to the scheme is inserted into the case. Outgoing voltage is monitored, the wires are powered, the case is locked.

Tip: the circuit may require additional load, it can be ensured by including a 15W light bulb in the system, which will also provide backlight.

Is it possible to connect the screwdriver directly to the charger

The screwdriver is convenient for its ubiquity. independence from limiting wires makes it possible to wade into hard-to-reach areas. A set of two power modules allows you to power one of them while working with the other. However, each battery pack has a finite number of charge / discharge periods, failing when they are used up. In inexpensive tools, blocks break faster, and the user receives a gadget with a working motor, but no power. Then the dilemma arises “is it possible to connect the screwdriver directly to the charging”.

You can feed such a screwdriver by connecting it to the network through a power supply unit, because its motor operates at 220 volts.

Using a power supply from a personal computer

On the radio market for a small cost, you can purchase an old power supply from a personal computer. We need a version of the “AT” format, which had to be turned off with the key after exiting the operating system.

Experienced users remember such system blocks. The advantage of such a power supply is also that it indicates an honest power. If it says 300W, then you can safely remove 15-16 amperes from the 12-volt output (again referring to Ohm’s law). This is enough to power an average screwdriver.

Such blocks have a power button in the kit. Another advantage is the presence of a cooling fan and an advanced overload protection system.

If you will hide the power supply in a beautiful case, do not forget to leave a hole for ventilation.

The connection is very simple. Black wire (-), yellow wire (12V).

Limitations. a screwdriver with a supply voltage higher than 14 volts will not work.

Using a car battery charger

The principle is the same as using a computer power supply. It is necessary to purchase an old charger for the starter batteries. The modern fashion for compact impulse chargers has left analog linear devices with manual control of voltage and charge current behind board. Therefore, such a device can be purchased on the automotive market for a symbolic cost.

Charger MAX INTER

It’s good if the voltage can be adjusted smoothly. in this case, your makeshift power supply will fit any screwdriver.

Converting it to a power tool is reduced to connecting the input of the electric motor to the power terminals of the charger.

Making a homemade power supply

If you are familiar with the principles of building electrical circuits, you can make your own power supply. Scheme giving general concepts. in the illustration.

The transformer can be picked up from an old tube TV, or other household appliances. Power 220 volts 250-350W. The main thing is the power supply. the donor should not be pulsed.

The voltage on the secondary winding is 24-30 volts. The secondary winding is made from a wire of the corresponding section.

However, if the output winding current is at least 15 amperes (see transformer specification), there is nothing to worry about.

After losses on the diode bridge (1-1.5 V on the diode), you will get the required output value.

If you have an electrical engineering education, make the calculation yourself. Or in a practical way: by connecting a 220 volt 100W incandescent lamp as a load, measure the output voltage. E

If it exceeds the needs of the screwdriver, reduce the number of turns of the secondary winding of the transformer.

We build in a ready-made power supply

To do this, you need to purchase a ready-made block with suitable characteristics and dimensions. There is enough such good on the radio markets.

Take the body with you and go to the fitting. When the desired power source is purchased, carefully separate it from the case.

We place the screwdriver in the battery box. All components must be securely fastened.

If necessary, extend the wires connecting the control board and the transformer. If the circuit touches the metal parts of the transformer during operation, a short circuit will occur.

Since the space in the case allows. separate the board and the transformer for better cooling. Whichever quality power supply you choose, the load will be high and overheating is possible.

It will not be superfluous to fix additional radiators on the power control microcircuits. Operate the screwdriver for a long time, disconnect it from the mains and touch the radio parts on the control board.

You yourself will understand which elements need heat dissipation. Holes can be made in the housing for air circulation.

Do-it-yourself rework of the power supply will not take much time, and the cost of the purchased module is incomparable with restoring the battery.

AC adapter for screwdriver in battery housing

If your tool is not too powerful, you can place the power supply in the handle or case from damaged batteries.

External power supply

The idea is not as absurd as it might seem. Even a large and heavy buck rectifier can just stand near the outlet.

You are equally tied to the power supply, and to the stuck mains plug. And the low-voltage cord can be made to any length.

IMPORTANT! Ohm’s law says. with the same power, decreasing the voltage. we increase the current strength! Accordingly, the 12-19 volt supply cord should have a larger cross section than 220 volts.

There is a way out. reworking the screwdriver in the network

Yes, it loses one of the benefits of a cordless tool. mobility. But for work in rooms with access to a 220 volt network, this is an excellent way out. Especially since you give new life to a broken instrument.

There are two concepts of how to make a network out of a cordless screwdriver:

We connect the screwdriver to the car battery

Drills and screwdrivers are some of the most essential tools for renovation work. They are used for drilling holes, twisting and untwisting screws, self-tapping screws, bolts.

These tools are powered by an electric motor that runs on the power of an electrical network or a battery.

It’s not a secret for anyone that screwdrivers powered by an electrical network are not always convenient to use, because often you have to use them far from outlets.

But the cordless version of the tool also has its drawbacks. Most of the inexpensive screwdrivers (you must admit that there is no need to buy an expensive tool for infrequent use) batteries quickly become unusable, and sometimes they simply do not have enough power. Do not worry! After reading this article, you will learn how to connect your screwdriver to a car battery. You only need to make small changes to the screwdriver.

You will need:

  • screwdriver
  • long Phillips screwdriver
  • file;
  • lighting wires (about 2 meters);
  • nippers;
  • sharp knife;
  • soldering iron;
  • solder;
  • insulating tape.

First, disassemble your tool with a screwdriver.

connecting, screwdriver, battery

Remove the top of the case and set it aside (until you need it). And put the second part in front of you.

Study the screwdriver device carefully. In the handle you will find two electrodes marked with the letters B (positive) and B- (negative).

The battery must be removed.

Remember or photograph the places of the internal parts of the tool (otherwise, in the end, you will not assemble a screwdriver, but an iron)

Stage three.

File the lower part of the housing symmetrically. It won’t come in handy in your new screwdriver. Although everything here depends only on your taste, you will not need this part, but if you leave it, nothing terrible will happen.

Stage 4.

To connect the tool to the battery, use a small cross-section of automotive lighter wires. The length should be approximately 2 meters. Cut the crocodiles with pliers, strip the loose ends.

Next, the wires should be connected to the terminals of the electrodes. In the case as in the photo, it was only necessary to thread the wires into the clamps and fix them with ordinary electrical tape. But, most likely, you will need soldering skills. This is perhaps the most difficult step of our mods.

Be sure to observe the polarity. Look at the correspondence of the charges of the electrodes and wires.

Wrap the connections with electrical tape. Make sure that no metal parts are visible. And the electrodes did not touch each other. Now feel free to put the screwdriver back together. Place the inner parts in the housing, lead the wires with clamps out. Fold the two halves of the tool together and tighten with the screws. Cover the part that you sawed off in step number 3 with electrical tape, thereby securing the resulting structure.

As a result, you will receive an excellent screwdriver that will serve you much more efficiently than the one that you had before the modification.

A nice addition is that now you can use your instrument on the road or in places where it was previously impossible to charge the instrument’s battery.

Cover the part that you sawed off in step number 3 with electrical tape, thereby securing the resulting structure.

As a result, you will receive an excellent screwdriver that will serve you much more efficiently than the one that you had before the modification.

A nice addition is that now you can use your instrument on the road or in places where it was previously impossible to charge the instrument’s battery.

The work of a screwdriver from a car battery. video review of photo alterations

But for skillful pens, a piece of advice applied in practice. Working with a cordless tool is very convenient due to its disconnection from the socket. But in the autumn-winter time, work at low temperatures does not allow for large volumes of twisting work, due to the rapid discharge of the battery. Exit: take the car battery, you can directly with the machine, the cable clings to the crocodiles (the copper is necessarily stranded, the thicker the better, the metro is 10-12 in length, but not from the welding unit) and clings to the contacts of the power tool inside the handle, using twists, scotch tape and etc. local. To work, not to recycle, the capacity of the car accumulator allows you to work for two days (experience with a screwdriver, when assembling a roof and a frame house as a whole, more than 700 self-tapping screws of a different format were screwed in 2 days), and there is no harmful effect on the subsequent start of the car. Yes, there is ultimately a minus in terms of mobility, but the torque is almost constant, unlike standard batteries, which also need to be charged in time, and then the electricity was turned off, where to charge it? It was not me who invented it, but my father, an experienced electrician. This is so that I do not run for a smoke break while the regular batteries are charging. And so I had to work from dark to dark.

The power tool can be harmful. Under heavy load (especially when the shaft stops), the voltage on the small battery sags, thereby limiting the maximum motor current. A car battery, due to its significantly higher capacity in such a situation, is capable of burning a screwdriver motor at once, or, more often, a speed controller located in a button. This thread has already discussed this issue. Alternatively, to limit the maximum current in series with a screwdriver, you can turn on a 55 watt car lamp.

About the work of the battery tool from the battery.
Over the weekend I made this adapter:

And for starters, having measured the distance, in a round stick I cut out 2 recesses for the contacts, and inserted it with the butt end into the base of chipboard:

Then, having drilled the holes, I stretched the cable and soldered it to the tin contacts fixed with nails: Well, at the end, having insulated, I got the following result

It holds quite tightly, which is facilitated by the bends at the end of the contacts. But you can additionally fix it to the handle. The main thing is not to forget where “” is on the wire (when connected to the battery). The length of the cable turned out to be about 5 meters, and when you connect a standard battery to it, you feel that some of the power is lost. When connected to a battery, I think it will be better, but the voltage is 16.8 (will it work)
