Abstract
A system for detecting information about rechargeable batteries having standard form factors, e.g. AA, C, D, etc., is disclosed. In one preferred embodiment, the invention includes a battery having a layer of insulating material with selective apertures. A charger is provided that senses the number and placement of the apertures to determine the particular battery configuration. Once the battery configuration is determined, the charger then charges the battery to apply a charging algorithm in accordance with the particular configuration. If a recognized battery configuration is not detectable, the charger does not charge, so as not to compromise the reliability of the battery.
