1. A method of charging a battery, the method comprising:

  • charging the battery cell with a first constant current in a first constant current mode;

    charging the battery cell with a first constant voltage in a first constant voltage mode;

    idle period of charging the battery cell after charging the battery cell in the first constant voltage mode;

    charging the battery cell with a second constant current different from the first constant current in a second constant current mode after idling the charging of the battery cell;

    charging the battery cell with a second constant voltage higher than the first constant voltage in a second constant voltage mode; and

    the charging capacity of the battery cell is calculated, wherein the idle period increases as the charging capacity of the battery cell increases.
