Produced amongst others by Wattz Electronics, the fission battery has taken on the role of an on-hand generator. Throughout the Mojave Wasteland, fission batteries can be found in New Vegas streets, remote shacks in the wastes, and reoccupied suburban homes. They are used for powering a wide range of devices, like street lamps, electronic signs, light-bulbs, and other household appliances and are easily scavenged from the common robot or appliance store, making it invaluable to the common wastelander in the absence of a reliable power grid.
