The LaserMax Replacement Battery Kit (brand part no. LMS319C) is a sleeved 4-pack of 1.5V silver oxide button-cell batteries sized for LaserMax factory-replacement guide rod lasers, not a laser itself. Swapping in a fresh set at least once a year keeps the laser performing consistently across temperature swings, and the sleeve keeps installation quick and mess-free.
