Mighty Max ML35-12GEL 12V 35AH GEL Rechargeable Battery — NB Replacement for Newton Computers 4300 (2-Pack)

ML35-12GEL is a 12V 35AH GEL rechargeable, maintenance-free battery sold as a pack of 2. Designed as an NB replacement compatible with Newton Computers 4300, this battery delivers reliable energy storage with the convenience of low-maintenance operation. Compared with AGM cells, the gel chemistry in these units exhibits a slower self-discharge rate, so they hold charge longer during periods of inactivity—making them an excellent upgrade option. Built to operate across a wide temperature range, Mighty Max GEL batteries maintain steady performance in both hot summers and cold winters, resisting the effects of temperature swings. Safety and durability are engineered into the design: a thick, non-spillable gel paste minimizes the risk of leaks and corrosive fumes, and the robust construction helps absorb vibration and shock in demanding applications. Backed by Mighty Max’s reputation for dependable products, this ML35-12GEL offering combines improved discharge characteristics, enhanced safety, consistent performance, and extended service life.
