Drained microfusion cell

The drained microfusion cell is a miscellaneous item in Fallout: New Vegas.

Characteristics
A drained microfusion cell is the byproduct of a spent microfusion cell. Identical in appearance to the charged version, they are microfusion cells with very little charge left in them. Not enough to power a shot from an energy weapon, but enough that, if a player gathers more of them, the remaining charge can be pooled together to make fresh, usable cells.

Recipes
Recycling; microfusion cells - With a Science skill of 25, a player can pool the leftover charge from 4 drained microfusion cells to make a fully-charged and usable microfusion cell.
 * Requires: Science 25, 4 drained microfusion cells
 * Creates: 1 microfusion cell

Efficient recycling; microfusion cells - With a Science skill of 50 and the Vigilant Recycler perk, a player can wring a little extra charge out of each drained cell, reducing the number of drained microfusion cells needed to make new ones.
 * Requires: Science 50; Vigilant Recycler; 3 drained microfusion cells
 * Creates: 1 microfusion cell
