Mighty Max ML9-12GEL 12V 9AH GEL F2 Replacement Battery for Celestron Power Tank - 2 Pack

ML9-12GEL is a 12V 9AH GEL rechargeable, maintenance-free battery (F2) supplied as a pack of 2 and designed to be compatible with Celestron Power Tank units. Engineered with GEL chemistry, these cells have a slower self-discharge rate than AGM batteries, so they retain their charge longer during storage — an ideal upgrade when longer standby life is needed. Built to perform across a wide temperature range, Mighty Max GEL batteries maintain reliable output in both hot and cold climates and resist performance loss from temperature swings. The thick, non-spillable gel paste construction reduces the chance of leaks and minimizes hazardous fumes, improving onsite safety. Rugged by design, these gel batteries tolerate vibration and shock better than liquid-electrolyte types, making them suitable for demanding environments. Backed by Mighty Max’s reputation for dependable power solutions, the ML9-12GEL offers the benefits of advanced GEL technology: improved discharge characteristics, enhanced safety, consistent performance, and extended service life.
