Abstract
A battering charging system is controlled by a microprocessor to charge and discharge batteries while periodically effecting monitoring and control operations in which battery current data are registered to accumulate capacity data in a memory and to thereafter display such data which includes both charge and discharge capacity data. The system has different modes of operation which may be selected by a user, including a charge mode, a discharge mode and an autocycle mode. In the autocycle mode, efficiency rate data is computed and displayed.
