The energy cell is a type of ammunition in Fallout 3.


Energy cells in Fallout 3 bear a striking resemblance to 3 regular AA batteries attached to each other.

Energy cells are most commonly found on destroyed robots, but merchants also sell them in large amounts. They are sold for at least 2 caps each.
