Abstract

Method and system for communication between a battery power receiving device and a battery pack are disclosed. The battery power receiving device has a battery information circuit that is carried with the battery power receiving device as a single unit. Battery information such as battery identification and capacity are stored in the battery power receiving device and the battery information circuit. The battery power receiving device uses the battery information if the battery identification stored therein coincides with the battery identification stored in the battery information circuit.
