Mighty Max ML35-12GEL 12V 35AH GEL Replacement Battery for John Deere STX30

ML35-12GEL is a 12V 35AH GEL rechargeable, maintenance-free battery designed as a replacement for the John Deere STX30. Its gel electrolyte architecture gives it a lower self-discharge rate than AGM batteries, so it retains charge longer during storage and is a practical upgrade for seasonal equipment. Built to perform across a wide range of temperatures, this GEL battery maintains reliable output in both hot summers and cold winters. The dense, non-spillable gel paste reduces the chance of leaks or acid spills and limits harmful fumes, while the construction is engineered to resist vibration and shock for rugged, off-road use. Because it is maintenance-free, there’s no need to add water or check electrolyte levels. Backed by the Mighty Max name, the ML35-12GEL delivers consistent discharge performance, improved safety, dependable operation, and an extended service life compared with conventional designs.
