So screwdrivers are characterized by:
1. According to the battery type:

- Lithium-ion (Li-Ion) - it can be recharged an unlimited number of times.
2. According to the battery capacity: battery capacity prescribed numbers from 1.0 to 7.0, and is measured in amperes multiplied by the hours (Ah). Value interpreted as follows: the specified number of ampere drive can issue for an hour. But since no screwdriver consumes 1-5 A per hour, its usage time is extended from 2 to 8 hours.
