ML10-12GEL 12V 10AH GEL F2 Replacement Batteries for Opti-UPS 650E - 2 Pack

ML10-12GEL by Mighty Max is a 12V 10AH GEL rechargeable, maintenance-free battery with F2 terminals. This listing is for a pack of 2 batteries and is compatible with Opti-UPS 650E units. Built with gel-electrolyte construction, these batteries have a lower self-discharge rate than AGM types, so they hold charge longer during storage and idle periods. Designed to operate reliably across a wide range of temperatures, they deliver consistent power whether used in hot or cold environments. The thick, non-spillable gel paste reduces the chance of leaks and corrosive fumes, improving safety in everyday use. That gel construction also helps the cells resist vibration and shock, making these batteries suitable for tougher, demanding applications. Backed by Mighty Max’s reputation for dependable products, the ML10-12GEL offers the advantages of GEL technology: improved discharge behavior, enhanced safety, dependable performance, and extended service life.
