Mighty Max ML9-12GEL 12V 9AH GEL F2 Replacement Battery Compatible with APC Back-UPS BX1500, UPSXS — 8 Pack

ML9-12GEL is a maintenance-free, rechargeable 12V 9AH GEL battery with F2 terminals, offered here as a pack of 8. Intended as a direct replacement compatible with APC Back-UPS BX1500 and UPSXS units, this gel battery is built for dependable backup power. Compared with AGM cells, these GEL batteries have a slower self-discharge rate, so they hold charge longer when idle—making them an excellent upgrade choice. They deliver reliable output across a wide temperature range, maintaining steady performance in both hot and cold conditions thanks to strong resilience against temperature fluctuations. Constructed with a thick, non-spillable gel paste, the design minimizes the chance of leaks and reduces the risk of acid spills and harmful fumes. The gel construction also improves resistance to vibration and shock, making these units suitable for tougher operating environments. Backed by Mighty Max’s reputation for quality and reliability, these batteries leverage advanced GEL technology for improved discharge characteristics, enhanced safety, better overall performance, and an extended service life.
