Mighty Max ML35-12GEL 12V 35AH GEL Battery — Replacement for Fortress 1600ACV

ML35-12GEL is a 12V 35AH GEL rechargeable, maintenance-free battery designed as a direct replacement for the Fortress 1600ACV. Longer charge retention: Gel construction gives this battery a slower self-discharge rate than AGM batteries, so it holds its charge longer when not in use — a practical upgrade for standby or intermittent applications. Reliable across temperatures: Mighty Max GEL cells sustain steady power delivery in a wide range of climates and remain dependable through both hot summers and cold winters. Built for tough conditions with improved safety: The thick, non-spillable gel paste minimizes the chance of leaks and acidic fumes. This sealed design also helps the battery resist vibration and shock, making it suitable for rugged environments. Proven reputation: Mighty Max is known for dependable products. The ML35-12GEL leverages GEL technology to offer improved discharge performance, enhanced safety, reliable operation, and an extended service life.
