Battery and method of power conservation for the same

A battery comprising:

• a bare cell including an electrode assembly in a case, the electrode assembly having a plurality of electrodes and a separator for preventing a short circuit between the plurality of electrodes;
• and
• a protective circuit coupled to the plurality of electrodes, wherein the protective circuit includes a remaining charge control circuit that internally detects a long-term nonuse state of the battery and blocks a current between the bare cell and the protective circuit when the long-term nonuse state is detected,
• wherein the remaining charge control circuit comprises:
• a state-recognition part adapted to determine and recognize the long-term nonuse state;
• and
• a conversion device part adapted to:
• block the current between the bare cell and the protective circuit in response to a determination result obtained through the state-recognition part;
• and
• convert the battery to a resting state,
• wherein the remaining charge control circuit comprises:
• a microprocessor, which includes:
• a timer adapted to measure an elapsed time;
• an accumulator adapted to accumulate the elapsed time as an accumulated time;
• a register adapted to receive at least one of a value of the accumulated time or a value of a voltage applied to the microprocessor;
• and
• a comparator adapted to compare at least one of the value of the accumulated time or the value of the voltage received in the register with a previously input value of a reference time or a reference voltage,
• wherein the remaining charge control circuit comprises:
• an inner current breaker coupled between the bare cell and the protective circuit, and
• wherein the inner current breaker includes a switch circuit including a first cutoff switch and a second cutoff switch coupled in parallel, the first cutoff switch being adapted to be turned on by a high-voltage signal from a charger and the second cutoff switch being adapted to be turned off by a predetermined signal of the microprocessor.
