Mighty Max ML9-12GEL 12V 9AH GEL F2 Rechargeable Replacement Battery for Skytron 3500B/6001/6500 — 8 Pack

ML9-12GEL is a 12V 9AH GEL rechargeable, maintenance-free battery with F2 terminals. Sold as an 8-pack, these batteries are designed as direct replacements compatible with Skytron 3500B, 6001, and 6500 models. Reliable power retention: GEL chemistry gives these batteries a slower self-discharge rate than AGM types, so they hold charge longer when idle — a practical upgrade for devices that sit unused between uses. Built to withstand temperature extremes: Mighty Max GEL batteries deliver stable output across a wide temperature range and tolerate temperature swings, providing dependable performance in both hot and cold environments. Rugged construction and improved safety: a thick, non-spillable gel paste reduces the chance of leaks and lowers the risk of acid spills and harmful fumes. The gel design also improves resistance to vibration and shock, making these units suitable for demanding applications. Trusted brand quality: Mighty Max is known for dependable battery products. These ML9-12GEL GEL batteries offer advanced gel technology for better discharge behavior, improved safety, enhanced performance, and a longer service life.
