Mighty Max ML12-12GEL 12V 12AH GEL F2 Replacement Battery (Compatible with Simplex 4009) - 6 Pack

ML12-12GEL is a 12V 12AH GEL rechargeable, maintenance-free battery supplied as a pack of 6. Low self-discharge: These GEL cells retain charge longer than AGM batteries thanks to a slower self-discharge rate, making them an excellent upgrade when standby capacity matters. Reliable across temperatures: Designed to deliver steady power in a wide range of climates, the batteries tolerate temperature fluctuations and maintain dependable performance in both hot and cold conditions. Built for tough environments with safety in mind: The sealed, thick gel paste is non-spillable and far less likely to leak, reducing the chance of acid spills and harmful fumes. Robust construction also helps the batteries withstand vibration and shock, suitable for demanding applications. Trusted brand performance: Mighty Max has a reputation for dependable batteries—this model leverages GEL technology for improved discharge characteristics, greater safety, enhanced overall performance, and an extended service life.
