ABSTRACT:
An improved arrangement for powering a two-way portable radio or the like comprises rechargable battery cells and sets of power input and output contacts interconnected to each other and the battery cells in such a way that the output contacts may be electrically connected to the battery cells for powering the radio, or to the input contacts for receiving power directly from a battery charger for dead battery operation while simultaneously recharging the battery cells, all battery pack contacts being electrically isolated from the battery cells in the latter mode of operation.
