Vigilant Recycler

Vigilant Recycler is a perk

Effects
The Vigilant Recycler perk makes you twice as likely to recover drained cells when you use Energy weapons and improves the conversion ratio when recycling drained cells from 4:1 to 3:1. If Gun Runners' Arsenal is also installed, it unlocks the "optimized" variant for every energy weapons ammo type (ECP, MFC, Energy cell, and Flamer fuel). All optimized cells share the same basic effects of increasing damage output by 30%, reducing the enemy DT by -5 and increase weapon degradation rate by 10%.

Behind the scenes
The perk description "Waste not, want not" refers to the original quote attributed to Benjamin Franklin, who was noted for his frugality.

Bugs
Taking this perk will sometimes permanently alter the workbench crafting list, and will prevent new schematics from appearing at the workbench.
