Mighty Max ML10-12GEL 12V 10AH GEL (F2) Replacement Battery for Simplex 4009 - 2 Pack

ML10-12GEL is a 12V 10AH GEL rechargeable, maintenance-free battery sold as a pack of two. These GEL units have a slower self-discharge rate compared to AGM batteries, so they hold their charge longer when not in use — making them an excellent upgrade option. Designed to perform reliably across a wide range of climates, Mighty Max GEL batteries tolerate temperature extremes and maintain steady power whether you’re using them in hot or cold conditions. The battery uses a thick, non-spillable gel paste that reduces the chance of leaks and the release of harmful fumes, improving safety during handling and operation. Built to withstand vibration and shock, this rugged design is suitable for demanding environments. Backed by Mighty Max’s reputation for quality and dependability, these GEL batteries offer superior discharge characteristics, improved safety, better overall performance, and a longer service life.
