Mighty Max ML35-12GEL 12V 35AH GEL Battery — Replacement for Neptune Sport Power Chair

ML35-12GEL is a 12V 35AH rechargeable, maintenance-free GEL battery from Mighty Max, designed as a direct replacement for the Neptune Sport power chair. Its GEL construction gives it a lower self-discharge rate than AGM batteries, so it holds charge longer during storage and is an excellent upgrade option for longer standby periods. Built to perform across a wide range of climates, this battery tolerates temperature fluctuations and delivers reliable power in both hot and cold conditions. The cell uses a thick, non-spillable gel paste that minimizes leaks and the risk of acid spills or harmful fumes, and the robust design resists vibration and shock—features that make it well suited for demanding, mobile applications. Backed by Mighty Max’s reputation for dependable batteries, the ML35-12GEL offers improved discharge characteristics, enhanced safety, solid performance, and an extended service life.
