Mighty Max ML9-12GEL 12V 9AH GEL F2 Replacement Battery for APC Back-UPS XS1500 / RBC109 / PS-1290 — 6 Pack

ML9-12GEL is a 12V 9AH F2 terminal GEL rechargeable, maintenance-free battery sold as a 6-pack. These units are designed as a direct replacement compatible with APC Back-UPS XS1500, RBC109 and PS-1290. Compared with AGM batteries, this GEL chemistry exhibits a slower self-discharge rate, so the batteries retain charge longer when not in use — making them an effective upgrade for standby applications. Built to perform across a wide temperature range, these batteries deliver dependable power in both hot and cold environments and tolerate temperature fluctuations without sacrificing performance. Safety and ruggedness are engineered into the design: a thick, non-spillable gel paste minimizes the risk of leaks and corrosive fumes, while the sealed construction helps resist vibration and shock for use in demanding conditions. Backed by Mighty Max’s reputation for reliability, these ML9-12GEL batteries provide the advantages of GEL technology — improved discharge characteristics, enhanced safety, strong performance and extended service life.
