The BA-53635/PLMD the a United Nations Space Command integrated non-replaceable battery for the Weapon/Anti-Vehicle Model 6 Grindell/Galileian Nonlinear Rifle (W/AV M6 G/GNR) "Spartan Laser" weapon.
It powers the Spartan Laser's blood red laser beams, which are incredibly vast in power and can destroy any enemy, infantry or vehicle, typically upon a single impact (except for heavy vehicles such as Wraiths, unless the exposed vehicle operator is directly shot[1] or the vulnerable circular vent on the rear is hit). However, the energy consumption for the M6 G/GNR is expectedly extreme, and the BA-53635/PLMD battery is drained in five laser shots.
The generator used to recharge the battery is the PP-16979/AM-Sh, however, the cost of the generator is to high for the generator to be used in the frontlines with most SPARTAN Laser units.
