Nowadays, you won’t surprise anyone with battery-powered tools. The very name of this tool already says a lot: that it is battery-powered and that it is mobile.
Let’s talk about the benefits
With a modern long-lasting battery, this tool will give you a long and reliable service, provided it has been used correctly.
The mobility of such a tool allows it to be used wherever it is required.
Therefore, it is battery-powered tools that most special services and most of the population have, knowing that it can work offline for a certain time. Especially in the trend now are reciprocating saws with great functionality.
Such tools are used in the construction of buildings, renovation of apartments, installation of electrical wiring and other similar works.
Cordless, electric or petrol tool
If you compare cordless and gasoline tools, the former will win, as it makes less noise during operation, and gasoline is not cheap now.
When compared with a power tool, the obvious advantage of a battery-powered tool is its mobility.
But still, the battery charge is not eternal, so it needs recharging from the mains.
Autonomous time when using one battery is several hours, which is quite a bit, but manufacturers calmly solve this problem by adding an additional battery to the box.
The most popular types of such tools are screwdrivers, drills and screwdrivers.
Disc plates, wrenches, grinders, electric jigsaws, routers, circular saws and garden shears are much less common.
Cordless punchers became available after the advent of Li-ion batteries.
The most important element is the battery.
Let’s take a closer look at one of the most important parts of the tool – the battery.
Most often, an external type model is used, but sometimes people buy with a built-in battery.
There are also models of tools that have the ability to place the battery remotely by connecting it with a wire to the tool. This reduces the weight of the tool.
There were models with a battery weight half the weight of the tool itself.
There are three types of batteries: NiMh (nickel metal hydride), Li-ion (lithium ion) and NiCd (nickel cadmium).

Power affects the duration of work in time, and voltage affects the power level of the tool itself.
At the moment, the largest battery capacity does not exceed 2,5 Ah, since with a larger capacity, its weight will increase greatly.
The power level, in terms of voltage, in the latest type of power tool is at least 7,2 V, as a rule, these are household electric screwdrivers.
The maximum voltage is 36V in the most powerful types of tools – perforators.
Features of the operation of power tools
In order for the battery to last as long as possible, you just need to be guided by the rules of use: the battery must be periodically used, otherwise it may deteriorate.
There are companies that sell tools with batteries that must be replaced with the same battery and no other.
Such tools are used from 2 batteries in the kit, thereby avoiding long-term stagnation of the battery under the conditions of use that are recommended by the developers themselves.
Thus, the price of such a set is reduced, because you will not need to immediately buy additional batteries.
The battery is very easy to move, no special efforts are required. At this time, you can put an additional battery for recharging.
Устройство
The device of the tool, which uses the battery as a generator, is similar to the design of analogues that operate from the network.
The main parts of the tool are:
- Frequency controller;
- Chuck for clamping;
- Control device with adjustment and others;
- And of course, the body itself.
The battery is usually inserted into the handle of the mechanism. It is either fully inserted inside the handle, or made in the form of a handle.
In angle grinders, the battery is located behind the handle to improve grip and protect yourself from accidental loss of the tool.
operating rules
If you want to use the tool correctly, you need to follow certain rules of operation:
- It is required to prevent overheating of the device in operation. If you do not follow this rule, you can burn yourself and damage the device.
- No need to leave the tool in the sun and under precipitation (rain, snow).
- It is required to store the tool in a dry place, the temperature of which does not exceed 50 degrees Celsius.
- It is necessary to charge the battery only in a proprietary charger. If this rule is violated, the device may break down without subsequent warranty repair.
The price of cordless tools can range from 4 to 120 thousand rubles, depending on the power and build quality, and the weight can reach 6 kg with the battery, which is not very much.

Such devices, due to their mobility and convenience, are an order of magnitude more expensive than those tools that work only from the mains.
But the opportunities that they give will justify themselves, and you can do any work while being far from the outlet. Also read about other electrician tools.
