  "textContent": "A secondary battery (100, 200, 300) that provides a usage voltage lower than a charged voltage. The secondary battery includes a chargeable/dischargeable battery cell (110), an external terminal (150, 250) electrically connected to the cell unit to charge and discharge the cell unit, and a protective circuit module (120, 320) including a current providing circuit (140, 340). The protective circuit module electrically connects the cell unit (110) to the external terminal (150). The current providing circuit includes a charge path (141) and a discharge path (142) that are separated from each other, a voltage drop unit (144, 344) dropping an output voltage of the cell unit to a usage voltage on the discharge path, and a reverse current preventing unit (143, 343) preventing reverse currents from flowing into the charge path and the discharge path.",
