The present invention is an electrical circuit for regulating the average current through and the voltage across a load, such as a rechargeable battery. The circuit includes at least one semiconductor switching device connected in series with the load for controlling the current through the load. A current control loop is provided in the circuit to maintain the average current through the load at a constant level despite changes in the resistance of the load. Also provided is a voltage control loop which acts to limit the voltage across the load to a value below a predetermined voltage level.
