ML9-12GEL 12V 9AH GEL F2 Replacement Battery for APC Smart-UPS SC 420VA 4-Outlet UPS - 6 Pack

ML9-12GEL is a maintenance-free, rechargeable 12V 9AH GEL battery sold as a 6-pack. Manufactured by Mighty Max, these gel batteries use an immobilized electrolyte (non-spillable gel) that reduces the risk of acid leaks and harmful fumes while improving resistance to vibration and shock.

Compared with AGM cells, GEL chemistry offers a slower self-discharge rate, so these units retain charge longer during storage and are a strong upgrade choice for standby power. Engineered to deliver reliable performance across a wide range of temperatures, they provide consistent output in both hot and cold conditions.

Equipped with F2 terminals, this pack is compatible as a replacement for APC Smart-UPS SC 420VA 4-Outlet UPS models, offering enhanced safety, stable discharge characteristics, and a longer service life backed by Mighty Max’s reputation for dependable batteries.
