ML15-12GEL 12V 15AH GEL F2 Replacement Battery — Compatible with UPS APC RBC4 PC12-12 — 2 Pack

ML15-12GEL is a rechargeable, maintenance-free 12V 15AH GEL battery sold as a pack of 2. This F2-terminal replacement is compatible with UPS models including APC RBC4 and PC12-12. Compared to AGM batteries, these GEL cells have a slower self-discharge rate, so they retain charge longer when idle — an ideal upgrade for standby power. Built to perform across a wide range of temperatures, Mighty Max GEL batteries deliver dependable power in both hot and cold environments. The internal thick, non-spillable gel paste reduces the chance of leaks, limits harmful fumes and lowers the risk of acid spills, while the robust construction resists vibration and shock for use in demanding conditions. Backed by Mighty Max’s reputation for reliability, this advanced GEL technology provides superior discharge characteristics, improved safety, better overall performance and a longer service life.
