ML10-12GEL 12V 10AH GEL F2 Replacement Battery Compatible with APC Back-UPS420, 420Pro - 2 Pack

ML10-12GEL (Mighty Max) is a 12V 10AH GEL rechargeable, maintenance free battery — Pack of 2. This battery is a direct replacement compatible with APC Back-UPS420, 420Pro. Its GEL chemistry features a slower self-discharge rate compared to AGM batteries, so it retains charge longer when idle and makes a superior upgrade for standby use. Designed to perform reliably across a wide temperature range, these batteries sustain consistent power in both hot and cold conditions. A thick, non-spillable gel paste minimizes leaks, reduces the risk of acid spills and harmful fumes, and increases resistance to vibration and shock—ideal for demanding or mobile environments. Backed by Mighty Max’s reputation for quality and reliability, these GEL batteries deliver improved discharge characteristics, enhanced safety, better overall performance, and a longer lifespan.
