ABSTRACT:
A circuit is disclosed which extends the useful life of a battery by regulating the power supplied from the battery to a load, such as a highway warning lamp, as the battery voltage decreases from age and use. The circuit supplies current from the battery to the load over periods of time which are automatically varied in length according to the battery terminal voltage, thereby maintaining the average power consumption at a fixed level throughout the useful life of the battery.
