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


The name "fission battery" seems to imply that the device's functionality is somehow linked to the process of nuclear fission, which is used to generate electrical energy. Even though the exact workings of this item are never explained, it demonstrates the obsession of the pre-War American society of the Fallout universe with nuclear technologies replacing normal tech (see also: Divergence). However, it is worth noting that even at the level of pre-war technology in the Fallout Universe it would still be incredibly difficult to harness full blown fission at such a small scale. As such, it is likely that the fission battery is simply a form of RTG instead of a tiny nuclear reactor. As the batteries can often be found in robots, they seem to be their primary energy source. 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.

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 3Edit

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 VegasEdit


Fallout 3Edit

  • Reilly's Rangers
    • A fission battery is required for fixing an access elevator during the quest, at the top of the Statesman Hotel. One can be found inside the hotel, but it is much easier to keep one extra in your inventory and bring it along for the quest.
  • A fission battery is used in the construction of the railway rifle.
  • A Spoonful of Whiskey
    • 6 fission batteries are required for the Point Lookout repeatable quest.

Fallout: New VegasEdit


  • 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.
  • Many oversized batteries can be found attached to portable lamps in various dungeons, such as Vault 22. These may not be taken and only serves as a cosmetic effect.
  • 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.
