Abstract
An electronic device which is capable of performing high-accuracy remaining battery capacity management. The electronic device has a plurality of battery pack compartments assigned specific addresses, respectively. A remaining capacity-detecting unit detects the remaining battery capacity of a battery pack mounted in a battery pack compartment. A control microcomputer receives information indicative of a remaining battery capacity sent from a battery pack accommodated in one of the battery pack compartments and address information on the battery pack compartment, and sends correction information concerning the remaining battery capacity to the battery pack.
