1. A method for regenerating charge capacity of a battery, the method comprising:

  • discharging the battery using a discharge circuit;

    detecting that a charge level of the battery is below a first and threshold, comprising;

    measuring the charge level of the battery; and

    comparing the measured charge level to the first threshold; and

    after the detecting, applying a bias voltage across the battery using a bias circuit, the bias voltage being smaller than a minimum voltage necessary to charge the battery.
