This section is transcluded from Fission battery. To change it, please edit the transcluded page.

Fission batteries are a pre-War portable power source, often found in robots and vehicles.[1][2] Throughout the Mojave Wasteland, fission batteries can be found in New Vegas streets, remote shacks in the wastes, and reoccupied suburban homes. Additionally, fission battery acid can be used in the distillation of certain alcohols.[3][4]




  • Numerous oversized fission batteries can be found hooked up to streetlights. 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 locations, such as Vault 22. These may not be taken and only serve as a cosmetic effect.


  1. Pioneer Scout camp terminal entries; Pioneer badge exam terminal, Chemist: "Before our vehicles ran on the fission battery, we used a totally different source of power. What chemical did we used to use to power our vehicles?"
  2. Multiple required to reprogram Primm Slim during My Kind of Town
  3. Used as ingredients in Cass' moonshine and during A Spoonful of Whiskey
  4. The Lone Wanderer: "I'm ready. Let me know what you need for your tonic."
    Marguerite: "There aren't too many ingredients, but I brew large batches, so we need a good bit of each. We'll need Punga Fruit, Yeast, and some Fission Batteries - for that extra little kick."
    The Lone Wanderer: "Batteries? For extra "kick"?"
    Marguerite: "You best keep this one to yourself, sweetie. The family tonic gets real kick from our secret ingredient. We just need a lil' bit of battery acid. Oh, don't look like that, now. You reckon I'd be around to tell you about it if it weren't safe enough? Bring me six fission batteries and I'll scrape 'em into the mix."
