Abstract
A method and apparatus for charging a rechargeable battery (110) that takes into account the use patterns of the particular battery. A user may only discharge the battery a little and recharge it frequently which is a low capacity high life cycle use pattern, or discharge the battery almost completely and place the battery on charge less frequently indicating a high capacity low life cycle use pattern. Herein, a battery is installed in an electronic device wherein a battery discharge determination circuit and a discharge determination algorithm determine the discharge level of the battery when a charging circuit is placed on the battery. The measurement algorithm determines from the rechargeable battery discharge level measurement how to recharge the rechargeable battery. The measurement algorithm may also determine how to recharge the rechargeable battery based on a plurality of previous measurements stored either in the electronic device or the battery.
