Mighty Max ML35-12GEL 12V 35AH GEL NB Replacement Battery — Compatible with Swish-Err 1850H

ML35-12GEL is a rechargeable, maintenance-free 12V 35AH GEL battery from Mighty Max. Designed to hold its charge longer than AGM batteries thanks to a slower self-discharge rate, it’s an excellent upgrade for applications that sit idle for extended periods. Built to perform across a wide temperature range, this GEL battery maintains reliable power delivery whether you’re operating in hot summer conditions or cold winter environments, and it tolerates temperature swings without significant performance loss. Safety and ruggedness are core to its design: the thick, non-spillable gel paste greatly reduces the chance of leaks, acid spills, or harmful fumes, while also improving resistance to vibration and shock for demanding installations. Backed by Mighty Max’s reputation for dependable batteries, the ML35-12GEL leverages advanced GEL technology to provide superior discharge characteristics, improved safety, reliable performance, and an extended service life.
