Mighty Max ML9-12GEL 12V 9AH GEL F2 Replacement Battery — Compatible with Sola SDU 850 / SDU 850-5 (8-Pack)

ML9-12GEL is a 12V 9AH rechargeable, maintenance-free GEL battery supplied as an 8-pack and fitted with F2 terminals. Designed as a drop-in replacement for Sola SDU 850 and SDU 850-5 units, it combines steady power delivery with a compact, service-free design. Performance: GEL construction gives these batteries a slower self-discharge rate than AGM types, so they hold charge longer when idle and make a reliable upgrade for longer standby life and consistent discharge characteristics. Durability & temperature tolerance: Built to operate across a wide range of climates, these GEL cells maintain dependable output in both hot and cold conditions and resist performance loss from temperature swings. Rugged safety design: A thick, non-spillable gel paste minimizes the chance of leaks and harmful fumes while improving resistance to vibration and shock—qualities that suit demanding or mobile installations. Trusted quality: Manufactured under the Mighty Max name, these ML9-12GEL batteries offer enhanced safety, robust discharge performance, and extended service life compared to conventional wet-cell alternatives.
