Mighty Max ML9-12GEL 12V 9AH GEL F2 Replacement Battery for APC BackUps ES 8 Outlet 550VA (BE550R) - 6 Pack

ML9-12GEL from Mighty Max is a 12V 9AH GEL rechargeable, maintenance-free battery sold as a pack of 6. Compatible with APC BackUps ES 8 Outlet 550VA (BE550R) and equipped with F2 terminals, these units are built for dependable replacement use. The thick, non-spillable gel paste construction reduces the chance of leaks, acid spills and harmful fumes while improving resistance to vibration and shock—making them suitable for tougher environments. Compared to AGM batteries, the GEL chemistry exhibits a slower self-discharge rate so the batteries retain their charge longer when idle, providing more reliable standby power. Designed to perform across a wide range of temperatures, these batteries deliver consistent output in extreme conditions. Backed by Mighty Max’s reputation for quality, the ML9-12GEL line offers improved discharge performance, enhanced safety, better overall reliability and a longer service life.
