We have rechargeable battery service center for battery drills, battery cordless screwdrivers and all equipment’s work with pack batteries. Is it wrong to admit that electric drill batteries has been made of only one battery. In 98% of the devices they are just one plastic box full with small "N" pcs batterie cells. Most of the time every single battery cell is 1.2V with different Amperes from 1,.2 to 2 A
Amperes is the value of measurement of current, it shows the power of Battery. As bigger value of amperes is the battery as much longer live and power has the battery.
Problems with cordless drills are most common because they are maybe most usable work devices.
