Is it possible to charge a car battery with an electric screwdriver

An electric screwdriver with an autonomous power source is definitely one of the best inventions of mankind, and it greatly facilitates the life of almost the entire male half of the world’s population. Collect furniture from IKEA, install a shelf in the bathroom for toilet supplies or squeeze the screws in the car, all this can be done using this power tool. And the most important charm of the battery electrical screwdriver is that it does not require, somewhere nearby an electric outlet, since it is equipped with a portable battery. But the power element that is equipped with this device should sometimes be recharged after intensive operation of the device. Just for this, there is a special charger with this manual power tool, which sometimes can break at the most inopportune moment.

Is it possible to charge an electric screwdriver when not at hand of its standard charging

If it happened, so an electric screwdriver was urgently needed, and its battery is discharged and there is no charging device that is suitable for it, you can charge the battery with a screwdriver for this, you need to do the following manipulations:

  • Disconnect the discharged battery from the handle of an electric screwdriver;
  • Determine the capacity and operating voltage of the battery, these data are usually written on the casing of the power source;
  • Configure the flow of current in the automotive BOD according to the electrical parameters of the battery of an electric screwdriver;
  • Connect a car charger without violating the polarity to the terminals of the battery and charge it for about 30 minutes under a personal vigilant supervision.

Make sure the battery is discharged

There are several ways to understand that the battery is not charged:

  • Look at the indicator (red means that the battery needs to be charged);
  • Use a multimeter (voltage of a charged battery on terminals of at least 12.6 V);
  • The load fork will show the voltage drop under load.

Tips to increase the service life of the smartphone battery


It is best to charge the battery with a standard charger that comes with a smartphone. These devices are made either by the manufacturers of smartphones, or under their control. Therefore, such charging devices satisfy all the requirements for charging the battery. Namely, voltage, power, output current, etc. D.

There are also third.Party manufacturers that produce certified chargers either for specific models or universal. But it is quite difficult to find them on sale, since the shelves are full of fake BOD, produced without any control from the manufacturer. If you charge the battery of the phone with such devices, then this will not help increase its service life. All of the above is true and with respect to an anti.Suggestion smartphone with a powerful battery. Return

Storage of a smartphone battery

Heating negatively affects the condition and service life of the LI-IN accumulator of the smartphone. Foreign experts conducted a number of studies on the influence of environmental temperature on the degree of battery discharge during its storage. The results can be seen in the table below.

The temperature of the OS, the battery gap with the initial degree of charge of 40%of the battery discharge with the initial degree of charge of 100% The temperature of the OS, the battery gap with the initial degree of charge of 40%of the battery discharge with the initial degree of charge of 100%
0 2 percent per year 6 percent per year
25 4 percent per year 20 percent per year
40 15 percent per year 35 percent per year
60 25 percent per year 40 percent per year

From the data obtained, we can conclude that the smartphone’s battery is best stored at a temperature of 15 grap and the degree of charge of about 50 percent. And what to do if there is no smartphone, and the battery needs to be charged? Read the material on how to charge a phone battery without a phone. Return

Why depends a successful acquisition of a battery?

First of all, from your intuition and selected characteristics. We will not be able to help with the first, but with the second we will try. Each screwdriver has its own set of characteristics. Which one is suitable for you? Solve the buyer, with an eye on their needs and financial capabilities.

The first and most important criterion is the maximum effort that a battery can give. The male hand is capable of “issue” 4.5. 5 nm, for a screw up to 6 mm this is enough (and the hand does not strain). When selecting the tool, you should build on this indicator. A screwdriver with less effort is torture to twist. There will certainly be not many joy from such an acquisition.

Next, look at the battery capacity. This characteristic is more important in the work than the type of battery. The higher the container (measured in Ach), the longer the screwdriver will turn the screws. It is advisable to take a tool with the minimum work time from one charge of 3 or more hours. The type of battery itself does not play such a big role. In everyday life, Li-Ion batteries only the largest advantage-a slightly smaller period of self-discharge, which is useful when the work of the tool is built on the principle: “Twisted-put on a shelf and forgot for a month”. And everything, everything else is comparable. But it costs more.

Type of charger: automatic or simple. In the latter version, you will have to remove from charging over a certain time interval (it is indicated in the instructions for the screwdriver). The automatic charger will turn off the charging itself and with the help of LED indication will notify you that “everything is ready”.

The handle in the hand is conveniently “sitting”? Turning and reverse button under the index finger? The main rule: the tool should be as convenient for your hand.

Additional nuances include the presence of the opportunity to regulate the amount of effort. It is not critical that it is very useful when working with delicate materials and sizes. This also includes the presence of LED backlight and indication of the battery charge state.

Spindle lock will be spinning in manual mode. Best automatic, released the start button and the spindle is blocked. Not always, but can come in handy.

The comfort and life of your battery will depend on the compliance of the selected model by the above minimum. Now you know how to choose a battery.
