Mighty Max ML15-12GEL 12V 15AH GEL F2 Replacement Battery — Compatible with Guardian Trek G3 & G4, 2-Pack

ML15-12GEL is a 12V 15AH GEL rechargeable, maintenance-free battery supplied as a 2 pack. Designed with an F2 terminal, this Mighty Max GEL battery is a direct replacement option for Guardian Trek G3 and Guardian Trek G4 units. Compared with AGM batteries, these GEL cells exhibit a slower self-discharge rate, so they hold charge longer when left unused—making them an excellent upgrade choice.

Built to perform across a wide temperature range, the ML15-12GEL sustains reliable output in both hot and cold conditions and tolerates temperature swings without significant loss of performance. The battery uses a thick, non-spillable gel electrolyte that minimizes the risk of leaks, acid spills, and harmful fumes; this construction also improves resistance to shock and vibration for demanding applications.

Backed by Mighty Max’s reputation for dependable products, this GEL battery delivers improved discharge behavior, enhanced safety, consistent performance, and extended service life.
