Mighty Max ML35-12GEL 12V 35AH GEL NB Replacement Battery — Compatible with Optiway Technology 1700FS (4-Pack)

ML35-12GEL is a 12V 35AH maintenance-free GEL rechargeable battery supplied as a pack of 4 and compatible with Optiway Technology 1700FS. Its GEL construction uses a thick, non-spillable gel paste to minimize leaks and harmful fumes, improving safety for demanding applications. The design also resists vibration and shock, making these batteries suitable for rugged environments. Compared with AGM batteries, these GEL units exhibit a slower self-discharge rate, so they retain charge longer when not in use — an attractive upgrade for standby and seasonal equipment. Built to perform reliably across a wide temperature range, they deliver steady power in both hot and cold conditions. Backed by Mighty Max’s reputation for quality, these batteries offer improved discharge characteristics, enhanced safety, dependable performance, and extended service life.
