A fission battery is a miscellaneous item in Fallout 3 and Fallout: New Vegas.


The term "fission battery" seems to imply that the device's functionality is somehow linked to the process of Nuclear fission, probably some form of alpha//betavoltaic cell or direct charging generator, which is used to generate electrical energy. Even though the exact workings of this item are never undergone, it demonstrates the obsession of the pre-War American society of the Fallout universe with nuclear technologies replacing normal tech, as a means of evolution (see also: Divergence). As the batteries can often be found in robots, they seem to be their primary energy source, along with powering cars alongside Fusion cores.[1] After more than 200 years of inaction, some of the robots can be reactivated, demonstrating that the batteries are a very reliable form of energy storage. Nuclear energy has the potential to maintain a form for excessive amounts of time.

In post-war society, 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, while being easily scavenged from the common Robot or appliance store, making it invaluable to the common wastelander in the absence of a reliable power grid, if any.

Fallout 3

Fission Batteries are located throughout the Capital Wasteland, The Pitt, Point Lookout and Adams Air Force Base, usually in toolboxes or destroyed robots.

Fallout: New Vegas


  • Fission batteries are unusually heavy for an item of their size. This can most likely be attributed to the presence of heavy elements such as uranium or any other atomic isotopes and elements, that are necessary for a chain nuclear fission reaction to take place, and presumably to the thick shielding which would be required to protect humans from any harmful radiation released during the cell's operation on machinery use during daily activity.
  • Numerous oversized fission batteries can be found hooked up to streetlights in Fallout: New Vegas. These are apparently used to power their respective streetlights, and cannot be picked up or used for anything else, only as a component of appearance.
  • Another oversized battery can be seen in front of Doc Mitchell's House. It seems that one is enough to give power to the entire house.
  • The base price for fission batteries is 75 caps so they can be sold for a large profit to vendors both in Fallout: New Vegas and Fallout 3.
  • Fission battery is a reference to the real world atomic batteries which are used to power artificial pacemakers and space satellites.
