A rechargeable battery pack includes a rechargeable battery having a predetermined charge voltage, and a circuit for generating a control voltage depending on a battery voltage of the rechargeable battery so that the control voltage reaches a predetermined control voltage when the battery voltage reaches a predetermined charge voltage of the rechargeable battery. A battery charger for the rechargeable battery changes the charging control from constant-current to constant-voltage depending on whether the control voltage reaches the predetermined control voltage. |
