Abstract
A lockout circuit is provided in a battery pack (10) which blocks charging by incompatible chargers while allowing charging by a compatible charger (12). The battery comprises a battery cell or cells (22), and a switch circuit (24). The switch circuit blocks charge current until a switch disable signal is provided to a switch disable contact (18). The switch circuit provides a one way bypass so that the battery may provide power to a device. To eliminate voltage drop while powering a device, a current sense circuit is provided to detect discharge current, and disable the switch circuit.
