Rotary hammers with 1 battery
1 battery
— removable battery tools that come with one battery.This option allows you to use the tool right away, “out of the box”, but is poorly suited for long continuous work: breaks will certainly be required to charge the battery. Therefore, 1 battery in a set is less common than 2 batteries (see the relevant paragraph); on the other hand, this option is cheaper. With this in mind, it is worth paying attention to such a complete set mainly in two cases: if the breaks for charging are not important for you, or if the household already has a suitable second battery.
