Mighty Max ML10-12GEL 12V 10AH GEL F2 Replacement Battery for APC Smart-UPS SC 420VA (SC420) — 2 Pack

ML10-12GEL is a 12V 10AH GEL rechargeable, maintenance-free battery sold as a pack of 2. Designed as an F2 replacement compatible with APC Smart-UPS SC 420VA (SC420), this Mighty Max battery is built for dependable backup power. Its GEL construction uses a thick, non-spillable gel paste to minimize the risk of leaks and corrosive fumes while providing greater resistance to vibration and shock. Compared with AGM batteries, these GEL cells exhibit a slower self-discharge rate, so they hold charge longer when idle—making them an excellent upgrade choice. Engineered to deliver steady performance across a wide temperature range, they maintain reliable output in both hot and cold conditions. Customers rely on Mighty Max for proven quality; these batteries offer improved discharge characteristics, enhanced safety, solid overall performance, and an extended service life.
