摘要： A secondary battery that provides a usage voltage lower than a charged voltage. The secondary battery includes a chargeable/dischargeable battery cell, an external terminal electrically connected to the cell unit to charge and discharge the cell unit, and a protective circuit module including a current providing circuit. The protective circuit module electrically connects the cell unit to the external terminal. The current providing circuit includes a charge path and a discharge path that are separated from each other, a voltage drop unit dropping an output voltage of the cell unit to a usage voltage on the discharge path, and a reverse current preventing unit preventing reverse currents from flowing into the charge path and the discharge path.
