Mighty Max ML35-12GEL 12V 35AH GEL Battery — Replacement for NPower Flex XL 6-In-1 Powerpack

The ML35-12GEL is a 12V 35AH GEL rechargeable, maintenance-free battery from Mighty Max. Designed as a direct replacement for the NPower Flex XL 6-In-1 Powerpack, it offers dependable energy storage with the convenience of a sealed, maintenance-free design. GEL chemistry provides a lower self-discharge rate than AGM batteries, so the unit holds its charge longer when left unused. Built to perform across a wide range of temperatures, this GEL battery maintains reliable output in both hot and cold environments. Safety and durability are central to the design: a thick, non-spillable gel paste minimizes the chance of leaks, reduces the risk of acid spills and harmful fumes, and increases resistance to vibration and shock—making it appropriate for rugged or demanding applications. Backed by Mighty Max’s reputation for quality, the ML35-12GEL delivers improved discharge characteristics, enhanced safety features, consistent performance, and an extended service life.
