Mighty Max ML35-12GEL 12V 35AH GEL NB Replacement Battery for Apollo 1650 ETL Opener - 2 Pack

ML35-12GEL is a 12V, 35AH rechargeable, maintenance-free GEL battery sold as a 2-pack and intended as a replacement compatible with the Apollo 1650 ETL opener. These batteries use GEL NB construction to provide reliable standby and cycle performance. Longer charge retention: The GEL chemistry features a slower self-discharge rate than AGM batteries, so the cells hold their charge longer when left unused—making them an excellent upgrade for devices that spend time in storage. Built for temperature extremes: Mighty Max GEL batteries deliver steady output across a wide range of climates, maintaining dependable power whether operating in hot summers or cold winters. Rugged, safer design: A thick, non-spillable gel paste minimizes the risk of leaks and corrosive fumes. The sealed GEL format also resists vibration and shock, making these units suitable for demanding or mobile applications. Trusted performance: Manufactured by Mighty Max, these GEL batteries offer improved discharge characteristics, enhanced safety, consistent performance, and an extended useful life compared to conventional options.
