Abstract

An electrical power supply for a hand portable cellular radio telephone having receiver and transmitter stages (3,4) operable at different voltage levels comprises a stack of series-connected rechargeable voltaic coils 5a-5f. In call mode both the receiver 3 and transmitter 4 are powered by the full cell stack developing maximum voltage, e.g. 7.2V. In stand-by the transmitter 4 is disabled by a switch S3 and the receiver 3 is powered by half, a group of, preferably the cells 5a-5c or 5d-5f providing only a portion of, preferably half, the full voltage e.g. 3.6V. Power consumption is thus reduced, e.g. by 10 - 15 mA, in stand-by mode thus increasing battery life. Switches S1 and S2 are operated in tandem in the stand-by mode to connect alternately the first half of the cell stack 5a-5c and then the second half of the cell stack 5d-5f on a periodic basis. <IMAGE>
