Cells
From QWiki
Cells are a type of ammunition used to power the Lightning Gun, also called Thunderbolt. A player can carry no more than 100 cells. As all ammo cells respawn after 15 seconds (dmm3) or 30 seconds (dmm1) after picking up.
Cells come in two types of boxes: small and large. Small boxes contain 6 rounds while large ones contain 12 rounds.
For Mr. Thunderbolt. A small battery has 6 charges, lasting a little over a second.— Quake 1 Manual
