Abstract
An electronic device includes a battery capacity computing unit configured to compute a current full-charge capacity of a currently inserted battery apparatus having secondary cells. The battery capacity computing unit acquires at least information on a full-charge capacity of the battery apparatus in a brand-new state and information on the battery charge/discharge cycle count from the battery apparatus, retains a correction coefficient used when computing the current full-charge capacity of the battery apparatus, and calculates the current full-charge capacity of the battery apparatus using the information on the full-charge capacity of the battery apparatus in a brand-new state, the information on the battery charge/discharge cycle count, and the correction coefficient.
