Abstract

An apparatus and method for conditioning batteries incorporates a programming device having different signatures for batteries of different characteristics. When a battery is to be conditioned, one of the programming devices representing the characteristics of that battery is attached to the battery and the combined battery/programming device is positioned on the battery conditioner. A surface of the conditioner contains a reading device that reads the signature of the programming device and automatically programs the discharging/charging circuits to provide a discharge/charge sequence that is tailored to the particular characteristics of the battery being conditioned. Programming devices can include mechanical complementary protrusions and apertures, bar codes, magnetic strips, magnetic spots with Hall-Effect readers, electrical parameters, built-in wire coding, and other suitable complementary signatures and readers.
