ML9-12GEL 12V 9AH GEL F2 Replacement Battery for APC Back-UPS Pro 1300/1500 — 6 Pack

ML9-12GEL is a rechargeable, maintenance-free 12V 9AH GEL battery supplied as a pack of 6, designed as a drop-in replacement for APC Back-UPS Pro 1300 and 1500 models. Compared with AGM cells, these GEL batteries have a slower self-discharge rate, so they hold their charge longer during storage or infrequent use. Built to withstand wide temperature ranges, Mighty Max GEL batteries deliver dependable power in both hot and cold conditions. The internal gel electrolyte is thick and non-spillable, minimizing the chance of acid leaks and fumes while improving resistance to vibration and shock — a good choice for demanding or mobile installations. Backed by the Mighty Max reputation, this GEL design offers improved discharge behavior, enhanced safety, consistent performance, and extended service life.
