PP-16979/AM-Sh

From Halopedia, the Halo wiki

The PP-16979/AM-Sh is the United Nations Space Command recharger for the Weapon/Anti-Vehicle Model 6 Grindell/Galileian Nonlinear Rifle (W/AV M6 G/GNR) "Spartan Laser" weapon.

It recharges the integrated non-replaceable BA-53635/PLMD battery of the Spartan Laser, also UNSC logistics are sufficiently ineffecient that most field Spartan Laser units are not accompanied with a PP-16979/AM-Sh recharger, and therefore have a limited use before discardment.
