Battery eliminator
From Wikipedia, the free encyclopedia
A battery eliminator is a device powered by an electrical source other than a battery, which then converts the source to a suitable DC voltage that may be used by a second device designed to be powered by batteries.
A battery eliminator does away with the need to replace batteries but may remove the advantage of portability. A battery eliminator is also effective in replacing obsolete battery designs.
Early commercial battery eliminators were produced by 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.
