Mighty Max ML9-12GEL 12V 9AH GEL F2 Replacement Battery for APC BackUps LS 500 BP500UC - 2 Pack

ML9-12GEL is a 12V 9AH GEL rechargeable, maintenance-free battery sold as a pack of 2. Designed to hold its charge longer than AGM types, these GEL cells have a slower self-discharge rate, making them an excellent upgrade if you need stored power that remains ready after periods of inactivity. Built to perform across a wide temperature range, Mighty Max GEL batteries deliver stable output in both hot and cold conditions thanks to their resistance to temperature swings. The internal electrolyte is a thick, non-spillable gel paste that minimizes leak risk and reduces the chance of acid spills and noxious fumes. That gel construction also improves resistance to vibration and shock, so these batteries stand up well in demanding or mobile applications. Backed by Mighty Max’s reputation for dependable products, this advanced GEL design provides improved discharge behavior, enhanced safety, dependable performance, and a longer service life.
