ML35-12GEL 12V 35AH GEL NB Replacement Battery Pack of 4 — Compatible with IMC Heartway Rumba HP3HD

ML35-12GEL is a 12V 35AH GEL rechargeable, maintenance-free battery sold as a 4-pack and designed as an NB replacement compatible with IMC Heartway Rumba HP3HD. These GEL cells provide steady, long-lasting power and feature a much slower self-discharge rate than AGM batteries, so they hold charge longer during storage. Built to perform across a wide range of climates, the batteries maintain reliable output in both hot and cold conditions. The internal construction uses a thick, non-spillable gel paste to minimize leaks and corrosive fumes, improving safety and reducing maintenance needs. That gel composition also helps the units withstand shocks and vibration, making them suitable for rugged or high-vibration applications. Customers rely on Mighty Max for quality and dependability; this model delivers enhanced discharge characteristics, improved safety, robust performance, and an extended service life.
