Battery voltage

Rated battery voltage for which the cordless tool is designed (see "Power Source").

Manufacturers select the battery voltage taking into account the performance characteristics of the tool and the power supply required to achieve these characteristics. In fact, this means that most often this parameter can be ignored at all when choosing. The only exceptions are some specific situations — for example, if the "household" already has a battery of the same company and you want to evaluate its compatibility with the selected model, if the selected tool is supplied without a battery and you want to immediately order a power source for it, or for accurate comparison of batteries by capacity (see below for more details). But after the purchase, the voltage data can also be useful for finding chargers in addition to or to replace the "native" charger.

As for specific values, in many models the voltage does not exceed 10 V — this is often quite enough. However, much more popular options are 11 to 15 V and 16 to 20 V. There are also higher voltages, but much less frequently.
