Mighty Max ML35-12GEL 12V 35AH GEL Replacement Battery for U1 Wheelchair / Werker WKDC12-33J — 2 Pack

ML35-12GEL is a 12V 35AH GEL rechargeable, maintenance-free battery sold as a pack of 2. Designed as a direct replacement compatible with U1 wheelchairs and Werker WKDC12-33J models, this GEL battery provides reliable power for mobility applications. Compared with AGM batteries, these GEL cells have a slower self-discharge rate, so they hold their charge longer when left unused—making them an excellent upgrade option. Built to perform across a wide temperature range, Mighty Max GEL batteries maintain steady output in both hot and cold conditions and tolerate temperature fluctuation without significant loss of performance. Safety and durability are enhanced by a thick, non-spillable gel paste that minimizes the risk of leaks, acid spills, and harmful fumes. The gel construction also helps the battery resist vibration and shock, making it suitable for rugged or demanding environments. Backed by Mighty Max’s reputation for quality, these GEL batteries offer improved discharge characteristics, greater safety, dependable performance, and extended service life.
