Mighty Max ML35-12GEL 12V 35AH GEL Replacement Battery for APC Smart-UPS SU1400NET

ML35-12GEL is a 12V 35AH GEL rechargeable, maintenance-free battery designed as a replacement for APC Smart-UPS SU1400NET. Its GEL formulation offers a lower self-discharge rate than AGM batteries, so it holds charge longer when stored and makes an effective upgrade in standby applications. Built to withstand wide temperature swings, this battery maintains reliable output in both hot and cold environments. The sealed gel paste is non-spillable, minimizing the chance of leaks and corrosive fumes while improving resistance to vibration and shock for use in demanding or mobile installations. Manufactured by Mighty Max, this model delivers improved discharge behavior, enhanced safety, dependable performance, and a longer usable life compared with older lead‑acid designs.
