Used to power the (very few) electronic devices you use that require them, namely the X-ray Detector.
"NeverReady double 'A' batteries."
- Most often found in the drawers and cupboards of houses, both in the countryside and in towns.
- Can be bought from Keith Hemps' general store, Jake Cameron's junk shop and Franz Hinkle's electronics store.
Pretty rare in the game, so stock up when you find them.
