A battery charging system is provided which is comprised of a battery pack (30) and a charging system (20). The battery pack (30) includes a battery (10) and a battery capacity detect circuit (32). The battery capacity detect circuit (32) is interfaced with the charging system (20) through a single line to output a CHG-Bar signal. The battery capacity detect circuit (32) is operable to perform numerous monitoring operations on the battery by detecting the charge input to the battery and detecting charge taken away from the battery in a discharge operation. This operation is performed independent of the charging operation by the charging system (20). However, the charging operation of the charger (22) can be affected with the CHG-Bar signal.
