Mighty Max ML9-12GEL 12V 9AH GEL F2 Replacement Battery (2-Pack) — Compatible with Black Decker CST1000 Cordless Trimmer

ML9-12GEL is a 12V 9AH GEL rechargeable, maintenance free battery. This listing includes a Pack of 2 units. Reliable power retention: GEL construction offers a slower self-discharge rate compared to AGM batteries, so these batteries hold their charge longer when not in use — an excellent upgrade choice for longer shelf life. Built to handle temperature extremes: Mighty Max GEL batteries deliver steady performance across a wide range of climates, maintaining dependable output whether operating in summer heat or winter cold thanks to their resilience to temperature fluctuations. Designed for tough environments with added safety: the thick, non-spillable gel paste reduces the chance of leaks and lowers the risk of acid spills and harmful fumes. The gel design also helps the batteries resist vibrations and shocks, making them suitable for rugged applications. Trusted quality: Mighty Max has developed a strong reputation for reliability. Benefit from advanced GEL technology for superior discharge characteristics, improved safety, better overall performance, and a longer lifespan.
