8-Pack 12V 9AH GEL F2 Replacement Battery (ML9-12GEL) — Compatible with APC BackUPS Pro 280PNP / 500CLR

ML9-12GEL is a 12V 9AH GEL rechargeable, maintenance-free battery with F2 terminals — sold here as an 8-pack and designed as a replacement compatible with APC BackUPS Pro 280PNP and 500CLR models. Longer standby life: These GEL cells exhibit a slower self-discharge rate than AGM batteries, so they hold their charge longer when unused — an ideal upgrade for extended storage or infrequent use. Reliable across temperatures: Engineered to deliver stable power in a wide range of climates, the ML9-12GEL maintains dependable performance whether operating in hot summer heat or cold winter conditions. Rugged, safe construction: The batteries use a thick, non-spillable gel electrolyte that reduces the risk of acid leaks and harmful fumes. That gel construction also improves resistance to vibration and shock, making these packs suitable for demanding applications. Trusted brand and benefits: Manufactured by Mighty Max, these GEL batteries offer improved discharge characteristics, enhanced safety features, robust performance, and a longer service life compared with conventional designs.
