Mighty Max ML9-12GEL 12V 9AH GEL F2 Replacement Battery — Compatible with APC Back-UPS XS1500 / RBC109 / PS-1290 — 8 Pack

Pack of 8 ML9-12GEL 12V 9AH GEL rechargeable, maintenance-free batteries designed as direct replacements for APC Back-UPS XS1500, RBC109 and PS-1290 (F2 terminal). These GEL cells have a slower self-discharge rate than AGM batteries, so they hold their charge longer during storage. Built to perform across a wide temperature range, they maintain reliable power in both hot and cold environments. The batteries use a thick, non-spillable gel electrolyte that minimizes leak risk and reduces harmful fumes, and their construction resists vibration and shock for demanding applications. Backed by Mighty Max’s reputation for dependable quality, these GEL batteries deliver improved discharge characteristics, enhanced safety, durable performance, and longer service life.
