Mighty Max ML12-12GEL 12V 12AH GEL F2 Replacement Battery — Compatible with APC SMC1500 / SMT1000 / UPS1000 (4-Pack)

ML12-12GEL from Mighty Max is a maintenance-free 12V 12AH GEL battery sold as a 4-pack and engineered as a drop-in replacement for APC SMC1500, SMT1000 and UPS1000 units. Its gel electrolyte gives it a slower self-discharge rate than AGM batteries, so it holds charge longer while idle — an easy upgrade for extended standby periods. Built to tolerate a wide range of climates, these GEL cells maintain reliable output through temperature extremes and rapid fluctuations, providing steady power in both hot and cold environments. The thick, non-spillable gel paste minimizes the risk of leaks and hazardous fumes and improves resistance to vibration and shock, making the batteries suitable for rugged or mobile installations. Backed by Mighty Max’s reputation, this advanced GEL design delivers improved discharge characteristics, greater safety, dependable performance and a longer service life.
