Mighty Max ML35-12GEL 12V 35AH GEL NB Replacement Battery — Compatible with Optiway Technology 1704FS (2-Pack)

ML35-12GEL from Mighty Max is a maintenance-free, rechargeable 12V 35AH GEL battery supplied as a 2-pack. Its GEL construction results in a slower self-discharge rate compared to AGM batteries, so the units retain charge longer during storage—making them an excellent upgrade or NB replacement for Optiway Technology 1704FS-compatible equipment. Engineered to deliver reliable power across a wide temperature range, these batteries perform consistently in both hot and cold conditions. The cells use a thick, non-spillable gel paste that lowers the chance of leaks and harmful fumes while improving resistance to vibration and shock, so they stand up well in demanding environments. Backed by Mighty Max’s reputation for quality, these GEL batteries offer improved discharge characteristics, enhanced safety, dependable performance, and extended service life.
