Mighty Max ML9-12GEL 12V 9AH GEL F2 Replacement Battery for APC Back-UPS Pro 1500 — 8 Pack

ML9-12GEL is a 12V 9AH GEL, rechargeable, maintenance-free battery with F2 terminals. This listing is for an 8-pack replacement set compatible with APC Back-UPS Pro 1500. Built on GEL technology, these batteries exhibit a slower self-discharge rate than AGM cells, so they hold charge longer during storage and make a reliable upgrade for standby power applications. Designed to perform across a wide temperature range, the cells maintain consistent output in both hot and cold environments and resist performance loss from temperature swings. The internal gel compound is thick and non-spillable, minimizing leak risk and reducing corrosive fumes while improving resistance to vibration and shock—ideal for demanding or mobile installations. Backed by Mighty Max’s reputation for dependable batteries, these GEL units offer improved discharge characteristics, enhanced safety, robust performance, and extended service life.
