Mighty Max ML9-12GEL 12V 9AH GEL F2 Replacement Battery — Compatible with APC Back-UPS BX1500, UPSXS (6-Pack)

ML9-12GEL is a 12V 9AH GEL rechargeable, maintenance-free battery sold as a pack of 6. These GEL cells hold charge longer than AGM batteries thanks to a slower self-discharge rate, making them an excellent upgrade for longer standby retention. Built to perform across a wide temperature range, Mighty Max GEL batteries maintain reliable output in both hot and cold conditions and tolerate temperature swings without compromising power delivery. The internal construction uses a thick, non-spillable gel paste that minimizes the chance of leaks and corrosive fumes while improving resistance to vibration and shock—ideal for demanding or mobile installations. Backed by Mighty Max’s reputation for dependability, this ML9-12GEL 6-pack delivers improved discharge behavior, enhanced safety, consistent performance, and extended service life.
