Mighty Max ML35-12GEL 12V 35AH GEL Replacement Battery — Compatible with Fortress 1600ACV

ML35-12GEL is a rechargeable, maintenance-free 12V 35AH GEL battery from Mighty Max. Designed for dependable, long-term use, this GEL battery exhibits a slower self-discharge rate than AGM batteries, so it holds charge longer during storage and is an excellent upgrade choice. Built to perform across a broad temperature range, the ML35-12GEL maintains consistent output in both hot and cold conditions. Its thick, non-spillable gel paste reduces the risk of acid leakage and harmful fumes, and the sealed construction increases resistance to vibration and shock—making it suitable for rugged or demanding applications. Backed by Mighty Max’s reputation for quality, this GEL design delivers improved discharge characteristics, enhanced safety, reliable performance, and an extended service life while remaining fully maintenance-free.
