Mighty Max ML35-12GEL 12V 35AH GEL Rechargeable Maintenance-Free Battery — 4-Pack (Replacement for R-4 Foldable Power Wheelchair)

ML35-12GEL is a 12V 35AH GEL rechargeable, maintenance-free battery supplied as a pack of 4. Designed as a direct replacement option for R-4 foldable power wheelchairs, these GEL batteries offer improved standby behavior thanks to a slower self-discharge rate compared to AGM batteries, so they hold their charge longer when idle and make a strong upgrade choice. Built to perform across a wide temperature range, Mighty Max GEL batteries maintain reliable output in both hot and cold conditions and tolerate temperature swings without significant loss of power. Safety and ruggedness are engineered into the design: a thick, non-spillable gel electrolyte minimizes the risk of leaks, acid spills, and harmful fumes, while the sealed gel construction resists vibration and shock for use in demanding environments. Backed by Mighty Max’s reputation for dependable batteries, these ML35-12GEL units deliver improved discharge characteristics, enhanced safety, consistent performance, and an extended service life.
