Abstract
A cellular telephone utilises a plurality of batteries with each battery having an associated charging circuit. Power is applied to the charging circuit from a charging device which device may be a mechanical rotating member. A control module is associated with each one of the charging circuits and selects the battery or cells of the battery to which the power is to be provided. If one battery or cell is being discharged, the charge is applied to the other non-used battery or cell. If one battery or cell is discharged and the phone is not being used, the power is applied to the lowest voltage battery or cell.
