Mighty Max ML35-12GEL 12V 35AH GEL NB Replacement — Compatible with Helios FB12-35 (2 Pack)

ML35-12GEL is a rechargeable, maintenance-free 12V 35AH GEL battery sold as a 2 pack and designed as an NB replacement compatible with Helios FB12-35. These GEL cells have a slower self-discharge rate than AGM batteries, so they hold charge longer when stored and are a smart upgrade for applications that sit idle between uses. Built to perform across a wide temperature range, Mighty Max GEL batteries deliver steady power in both hot summers and cold winters, thanks to their resilience to temperature fluctuations. The internal construction uses a thick, non-spillable gel paste that minimizes the chance of leaks, reducing the risk of acid spills and harmful fumes. That gel design also helps the batteries withstand vibration and shock, making them suitable for demanding or mobile environments. Customers rely on Mighty Max for dependable quality. Advanced GEL technology in the ML35-12GEL offers improved discharge behavior, greater safety, better overall performance, and an extended service life.
