Mighty Max ML35-12GEL 12V 35AH GEL Battery — 2-Pack NB Replacement for R-4 Foldable Power Wheelchair

ML35-12GEL is a 12V 35AH GEL rechargeable, maintenance-free battery sold as a pack of 2. Designed as an NB replacement for the R-4 Foldable Power Wheelchair, these GEL cells hold charge longer than AGM batteries due to a slower self-discharge rate, making them an excellent upgrade for devices that sit idle for periods. Built to perform across a wide range of temperatures, Mighty Max GEL batteries maintain reliable output whether you’re using them in high heat or cold conditions. The battery uses a thick, non-spillable gel electrolyte that greatly reduces the chance of leaks and acidic fumes, improving safety during handling and operation. Rugged by design, the gel construction also helps the unit resist vibration and shocks, so it’s well suited to demanding applications and mobile equipment. Backed by Mighty Max’s reputation for dependable power solutions, these ML35-12GEL batteries offer improved discharge behavior, enhanced safety, consistent performance, and a longer service life.
