Mighty Max ML35-12GEL 12V 35AH GEL Battery — 2-Pack Replacement for Revolution Mobility Liberty 520 Power Chair

ML35-12GEL is a 12V 35AH GEL rechargeable, maintenance-free battery sold as a pack of 2 and designed as a replacement for the Revolution Mobility Liberty 520 power chair. Compared with AGM batteries, these GEL cells have a slower self-discharge rate, so they hold their charge longer during storage and provide steady, long-lasting power in regular use. Built to perform across a wide range of climates, the batteries maintain reliable output in both hot summers and cold winters thanks to their resistance to temperature fluctuations. The internal construction uses a thick, non-spillable gel paste that minimizes leaks and the chance of acid spills or harmful fumes, while also improving vibration and shock tolerance for rugged, mobile applications. Maintenance-free and rechargeable, these Mighty Max GEL batteries offer enhanced safety, better discharge characteristics, consistent performance, and an extended service life.
