Energy cell (Fallout 3)

The small energy cell (SEC, but simply called energy cell in-game) is a type of small, self-contained energy storage unit, manufactured by Wattz Electronics in Fallout 3.

Gameplay attributes
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 robots, but merchants also sell them in large amounts. Unfortunately, they sell them for at least 2 caps each, making them quite pricey. If you have a lot of these, you can sell them for large amounts of caps.
