Abstract:
A rechargeable battery having a user-selected charge capacity, comprising:a. a rigid casing, the casing having an exterior surface; b. an electrochemical cell within the casing; c. a plurality of charge contacts accessible at the exterior surface of the casing, the charge contacts further in conductive contact with the electrochemical cell to allow charging of the electrochemical cell when a voltage is placed across the charge contacts; d. a charge control circuit within the casing, the control circuit in conductive contact with at least the charge contacts and the electrochemical cell, the control circuit including a voltage regulator that regulates the charge voltage from the charge contacts to the electrochemical cell; and e. a charge selector accessible at the exterior surface of the casing, the charge selector selectively alters the charging of the electrochemical cell.
