Mighty Max ML9-12GEL 12V 9AH GEL F2 Replacement Battery — Compatible with Minuteman Entrust ETR1500 (10 Pack)

ML9-12GEL is a 12V 9AH rechargeable, maintenance-free GEL battery from Mighty Max. Sold as a pack of 10, these GEL cells offer a slower self-discharge rate than AGM batteries, so they hold charge longer when left unused — a practical upgrade for standby and backup applications. Engineered to perform across a wide temperature range, they deliver reliable power in both hot and cold conditions thanks to strong tolerance for temperature swings. The thick, non-spillable gel electrolyte reduces the chance of leaks and corrosive fumes, improving safety and making the batteries less prone to acid spills. Their construction also helps absorb vibration and shock, making them suitable for tougher operating environments. Trusted by customers for consistent quality, Mighty Max GEL batteries provide improved discharge characteristics, enhanced safety, dependable performance, and a longer service life. Compatible with Minuteman Entrust ETR1500.
