ABSTRACT:
An automatic apparatus and method for charging a storage battery from a source of electrical current. The charger includes a current control circuit for conducting regulated charging current through the battery in steps. A voltage monitoring circuit determines when the steps occur by monitoring battery voltage conditions. The steps are sequenced by a ring counter that varies the bias conditions on the current control circuit and voltage monitoring circuit as the steps occur.
