  • Voltage. The higher the value, the less effort it takes to get the job done. At the same time, a high power rating requires more energy, which means the battery needs to be stronger as well.
  • Torque. The maximum torque is directly related to the intended use of the tool. In fact, it is responsible for the “strength” of the device. The higher this indicator, the easier it is for the screwdriver to screw large screws.
  • Rotation speed. This is the number of revolutions made by the spindle around its own axis in a unit of time. It is measured in revolutions per minute (rpm). The higher the speed of the drill, the higher its productivity.
  • Battery. The most commonly used types of batteries for an impact driver:
    • Li-Ion – more expensive than nickel batteries, but behind this price are weighty advantages, such as light weight, no “memory effect”, no self-discharge (presence in the smallest possible amount), good performance properties.
    • Ni-Cd – the most popular type of battery for a screwdriver, primarily due to its price. When choosing this type of battery, it is important to follow the instructions on how to charge it.
    • Ni-MH – released to replace the Ni-Cd type, its characteristics are not much inferior to its “big brother”, but it does not contain harmful cadmium, which means easier battery disposal.

Nickel batteries, compared to lithium-ion batteries, are more sensitive to the cold, which means that in winter it will be easier to work with them on the street.
