ABSTRACT:
A constant voltage battery charger comprising a voltage regulator adapted to be supplied with D.C. voltage having a predetermined, constant level, means for establishing a regulator output voltage predetermined to define, at a selected temperature, a charging voltage equal to the charging voltage of a battery at that temperature including an operational amplifier means for supplying a predetermined voltage to the non-inverting input of the operational amplifier, and variable means for supplying voltage as a function of regulator output voltage to the inverting input of the operational amplifier, the variable means being selectively variable over a given range so that the predetermined output voltage can be defined at the selected temperature.
