A battery charging circuit is described connected to a voltage source and the terminals of a battery for maintaining a charge on the battery comprising: input means connected to the voltage source; current regulating means connected to the input means for providing a constant current output to the battery; resistive means connected to the regulating means for selectively setting charging rate currents provided to the battery by the regulating means; switching means connected to the resistive means for controlling the operation of the resistive means; means for sensing the state of charge of the battery connected across the terminals of the battery; and integrated buffer circuit means connected between sensing means and the switching means to control the operation of the switching means in response to the state of battery charge sensed by the sensing means.
