Mighty Max ML9-12GEL 12V 9AH GEL F2 Replacement Battery — Compatible with Ion Block Rocker UPS Audio (8 Pack)

ML9-12GEL is a 12V 9AH GEL, rechargeable, maintenance free battery from Mighty Max. This listing is for an 8 pack. Long shelf life: the GEL construction gives these cells a slower self-discharge rate than AGM types, so they hold charge longer when stored and make a reliable upgrade choice. Wide temperature reliability: engineered to perform consistently across extreme climates, these batteries tolerate temperature swings while maintaining stable power output. Built for tough use and safer operation: a thick, non-spillable gel paste reduces the risk of leaks, acid spills, and harmful fumes, and the design resists vibration and shock for demanding applications. Trusted quality: Mighty Max is known for dependable production—benefit from GEL technology’s superior discharge characteristics, improved safety, consistent performance, and extended service life.
