A controller (10) controls the application of charge pulses and discharge (depolarization) pulses to a battery (26) via a charge pulse circuit (22) and a discharge pulse circuit (24). A feedback circuit (18) allows the controller to monitor and adjust the charging process. A wave shaper (12) shapes the waveform of the charge pulses so as to limit the rise time of the charge pulses and thereby reduce reflected voltages and currents. A limiter (14) disables the charging circuit in the event that the controller should specify a charge pulse having an excessive duration or a continuous duration. Another limiter (16) limits the duration of the discharge pulses in the event that the controller should specify a discharge pulse having an excessive duration or a continuous duration. The charge pulse circuit is disabled whenever the controller specifies the application of a discharge pulse, and the discharge circuit is disabled whenever the controller specifies the application of a charge pulse. This prevents the simultaneous application of a charge pulse and a discharge pulse.
