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


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 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.


Fallout 3Edit

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 serve 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.
