Mighty Max ML9-12GEL 12V 9AH GEL F2 Replacement Battery for APC RBC17 / UPS — 6 Pack

ML9-12GEL is a 12V 9AH GEL rechargeable, maintenance free battery sold as a pack of 6. Compared with AGM batteries, these GEL cells have a slower self-discharge rate, so they hold charge longer during storage — an easy upgrade for extended standby readiness. Built to perform across a wide range of climates, Mighty Max GEL batteries maintain reliable power through extreme temperature swings, delivering consistent output in both hot summers and cold winters. The design uses a thick, non-spillable gel paste that reduces the chance of leaks, minimizes risk of acid spills and fumes, and improves safety. That gel construction also helps the battery resist vibration and shock, making it suitable for demanding or mobile installations. Backed by Mighty Max’s reputation for dependable products, this GEL technology offers improved discharge characteristics, enhanced safety, solid performance and a longer service life.
