Abstract :
Effective amp hour (Ah) discharge capacity is an exponential function of discharge rate (current). Discharge and charge reversibly oxidize/reduce the active materials of the electrodes. Charging also produces water electrolysis. Terminal voltage shows hysteresis between charge and discharge. Tests of a previously reported voltage equalizing system showed the battery sensitivity to circuit impedance
