Abstract
A battery charger system is provided in which a microprocessor is used to discontinue application of a high charge current when the battery voltage drops below a peak value by a value greater than a threshold value corresponding to stored digital data. The microprocessor is also used to obtain a discharge mode of operation and an autocycle mode of operation in which a charge operation is performed after a discharge operation, the microprocessor being responsive to actuation of keys of a keyboard. In performing various operations, the microprocessor is used in performing analog-to-digital conversions and it is additionally used in computing energy capacity and efficiency.
