1. A method for decreasing the internal resistance or impedance of a battery or electrochemical cell having a rated capacity, the method comprising the step of discharging the battery or electrochemical cell beyond its rated capacity wherein it reaches an overdischarge condition and continuing the discharge to maintain the battery or cell in the overdischarge condition until the battery or electrochemical cell reaches between 102% and 140% of its rated capacity to effect a diminution of the internal resistance or impedance of a battery or electrochemical cell.
