ABSTRACT:
An electrical circuit is provided which is operable in a first mode to deliver electrical energy to the load of an energy-using device and to a rechargeable battery for charging thereof. The circuit is operable in a second mode to deliver energy to the load of the energy-using device alternatively from either the rechargeable battery or a non-rechargeable battery. The circuit includes a pair of discharge terminals spaced apart by a first preselected distance so as to engage the power terminals of either the rechargeable or non-rechargeable battery. The circuit includes a charging terminal spaced apart from one of the discharge terminals by a distance greater than said first distance so as to engage a terminal extension carried by one of the power terminal contacts of the rechargeable battery whereby only the rechargeable battery may be charged in the circuit.
