Mighty Max ML9-12GEL 12V 9AH GEL F2 Replacement Battery Pack of 4 — Compatible with APC Smart-UPS Rack Mount XR SU24R2XLBP

ML9-12GEL is a 12V 9AH GEL rechargeable, maintenance-free battery sold as a pack of 4. Designed with a thick, non-spillable gel paste, these batteries reduce the risk of acid leaks and fumes while providing improved resistance to vibration and shock — suitable for heavy-duty or mobile installations. Compared with AGM cells, the GEL chemistry exhibits a slower self-discharge rate, so the batteries hold their charge longer during storage or infrequent use. Built to perform across a wide temperature range, they deliver reliable power in both hot and cold conditions. Trusted Mighty Max construction and advanced GEL technology offer enhanced safety, steady discharge characteristics, and extended service life when used as replacements for APC Smart-UPS Rack Mount XR SU24R2XLBP (F2 terminals).
