Mighty Max ML9-12GEL 12V 9AH GEL F2 Battery — Replacement for Dell 500W (H900N), 2-Pack

ML9-12GEL is a 12V 9AH GEL rechargeable, maintenance-free battery sold as a pack of 2 and compatible with Dell 500W (H900N). Reliable charge retention: The GEL construction exhibits a slower self-discharge rate versus AGM batteries, so these cells hold their charge longer when not in use — a practical upgrade for standby and intermittent applications. All-weather durability: Mighty Max GEL batteries are engineered to perform consistently across a wide range of temperatures, delivering steady power in both hot and cold conditions. Built for rugged environments: Each unit uses a thick, non-spillable gel paste that reduces the risk of leaks, acid spills and harmful fumes. That gelified electrolyte also helps the battery withstand vibrations and shocks, making it suitable for demanding installations. Safety and longevity: Designed as maintenance-free rechargeable batteries, they combine advanced GEL technology with enhanced safety features for improved discharge behavior, dependable performance and an extended service life. Backed by Mighty Max: From a brand known for reliability, these ML9-12GEL batteries offer the safety, performance and lifespan benefits of GEL chemistry in a convenient 2-pack.
