Mighty Max ML9-12GEL 12V 9AH GEL F2 Replacement Battery — Compatible with APC Back-UPS RS BR800BLK (6-Pack)

ML9-12GEL is a 12V 9AH rechargeable, maintenance-free GEL battery with F2 terminals. This offering includes a pack of 6 batteries. The GEL design provides a slower self-discharge rate compared to AGM batteries, so these units retain charge longer when not in use—making them a smart upgrade for backup power systems. Built to perform across a wide range of temperatures, they maintain reliable output in both hot and cold conditions. Featuring a thick, non-spillable gel paste, these batteries reduce the risk of acid leaks and harmful fumes and are more resistant to vibration and shock—suitable for tougher environments and mobile applications. Backed by Mighty Max’s reputation for quality and dependability, these GEL batteries deliver improved discharge behavior, enhanced safety, reliable performance, and a longer service life. Compatible with APC Back-UPS RS BR800BLK.
