Abstract
Abstract Apparatus and method for conditioning batteries such as those of the nickel-cadmium type for which deep discharge prior to recharge is desirable. Mechanical programming plates having different patterns of apertures for batteries of different characteristics are provided. When a battery is to be conditioned, one of the programming plates having an aperture pattern representing the characteristics of that battery is attached to the battery and the combined battery/programming plate is positioned on the battery conditioner. A surface of the conditioner contains programming pins that sense the aperture pattern on the programming plate and automatically program the discharging/charging circuits to provide a discharge/charge sequence that is tailored to the particular characteristics of the battery being conditioned.
