Energy cell (Fallout: New Vegas)

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: New Vegas.

Gameplay attributes
Energy cells are the standard ammunition used by the majority of pistol energy weapons, and as such are widely available across the Mojave Wasteland.

Crafting
In Honest Hearts, a recipe for recharging drained energy cells was unlocked with 45 science added that required the use of a fission battery. With 5 drained energy cells and a fission battery, the player could convert them into 25 new energy cells.

Recycling
After firing, there is a chance that spent energy cells will turn into drained energy cells. These are automatically placed in the player character's inventory. Drained energy cells can then be recycled back into usable energy cells at a workbench.
 * See: comparison table for chances of drained energy cells being produced for each variant of energy cell.

Conversion
Energy cells can be converted into, and from, other energy weapon ammunition types (i.e. electron charge packs and microfusion cells) at a workbench, with the appropriate Science skill.
 * Conversion (type)

The player can also pool charges from good cells together to make more powerful variants, which improve damage and bypass more enemy DT but burn out weapon components faster.
 * Conversion (variant)

Notable locations

 * Hidden Valley bunker. If you gain accepted status or higher with the Brotherhood of Steel, you will be approached by a BoS initiate telling you they have placed recycled ammunition in a box at the bottom of the entrance stairs to the L1 area. The box will be replenished randomly with energy cells, microfusion cells and electron charge packs whenever you enter L1, giving a continuous supply of energy weapons ammunition.
 * Muggy can provide 50 a day.
 * Both ED-Es, with the right upgrade, can provide a small amount of small energy cells a day. ED-E can also make microfusion cells and flamer fuel.
 * When killed, Mister Gutsys will have about 3 to 6 rounds on them
 * Occasionally sold by Cliff Briscoe.
 * Regular and variants sold by Chet.
