 The term is also sometimes used as a misnomer when using a bigger battery for more runtime when branching out a power supply to wired electrical equipment using DC input.Early commercial battery eliminators were produced by the Edward S. Rogers, Sr. company in 1925 as a complement to his line of "batteryless" radio receivers.Another early producer of battery eliminators was the Galvin Manufacturing Corporation (later known as Motorola) which was opened on September 25, 1928 by Paul Galvin and his brother Joseph E. Galvin, to build battery eliminators for radio receivers installed in automobiles.
