ML9-12GEL 12V 9AH GEL F2 Replacement Battery for APC Back-UPS RS BR800BLK — 8 Pack

ML9-12GEL is a 12V 9AH GEL rechargeable, maintenance-free battery supplied as an 8-pack and designed as a direct replacement for APC Back-UPS RS BR800BLK. Engineered with GEL chemistry, these cells exhibit a slower self-discharge rate than AGM batteries, so they hold charge longer during storage and represent an effective upgrade option. Built to perform across a wide temperature range, Mighty Max GEL batteries resist the effects of temperature swings and deliver reliable power in both hot and cold environments. The internal construction uses a thick, non-spillable gel paste that minimizes the chance of leaks or corrosive fumes and enhances safety. That gel construction also helps the battery withstand vibration and shock, making it suitable for demanding or mobile applications. Backed by Mighty Max’s reputation for dependable products, this ML9-12GEL 8-pack offers improved discharge behavior, enhanced safety, consistent performance, and a longer service life compared to standard options.
