Mighty Max ML15-12GEL 12V 15AH GEL F2 Replacement Battery Compatible with APC Smart UPS 620NET, 650 - 2 Pack

ML15-12GEL is a Mighty Max 12V 15AH GEL rechargeable, maintenance-free battery sold as a pack of 2. Its GEL design features a slower self-discharge rate than AGM batteries, so these cells hold their charge longer when left unused — a reliable upgrade choice. Built to operate across a wide range of temperatures, these batteries maintain steady power in both hot and cold environments. The thick, non-spillable gel paste reduces the risk of leaks and acid fumes and provides strong resistance to vibration and shock, making the units suitable for rugged or mobile applications. Backed by Mighty Max’s reputation for dependable products, this GEL technology offers superior discharge characteristics, improved safety, consistent performance, and an extended service life.
