ML9-12GEL is a 12V 9AH GEL rechargeable, maintenance free battery supplied as a pack of 4. These Mighty Max cells are designed to be direct replacements and provide dependable standby power. Reliable performance: The GEL construction exhibits a slower self-discharge rate compared to AGM batteries, so these units retain charge longer when not in use — a practical upgrade for extended storage between uses. Durable across temperatures: Mighty Max GEL batteries maintain steady output in a wide range of climates, showing strong resilience to temperature fluctuations and delivering consistent power in both hot and cold conditions. Built for rugged applications with added safety: A thick, non-spillable gel paste reduces the chance of leaks, minimizing the risk of acid spills and harmful fumes. The gel design also improves resistance to vibration and shock, making these batteries suitable for demanding environments. Trusted quality: Mighty Max has established a reputation for reliable battery products. With advanced GEL technology, these batteries offer improved discharge characteristics, enhanced safety, solid performance, and an extended service life.
