ABSTRACT:
A universal battery charger and recharger for electric batteries having different charging characteristics. The battery charger includes a microprocessor receiving inputs from current, voltage and temperature sensors for controlling the battery charging profile. A replaceable memory may be included to provide an appropriate charging profile for the battery to be charged. The supply current is varied responsively to the voltage across the battery which is measured when the supply current reaches a predetermined level or after a predetermined time.
