The first manner displaying step includes the step of operating a battery charge level indicator in a first mode, and the second manner displaying step includes the step of operating the battery charge level indicator in a second mode which is different than the first mode. In addition, a battery charge level indicator is disclosed and includes a display for indicating a charge level of a battery, and a mechanism for operating the display so as to indicate whether the battery is in a charge state of operation or a discharge state of operation.
