ML12-12GEL 12V 12AH GEL F2 Replacement Battery for Simplex 4004R — 10 Pack

ML12-12GEL is a 12V 12AH GEL rechargeable, maintenance free battery sold as a pack of 10. Designed as an F2 terminal replacement compatible with Simplex 4004R, this gel cell offers reliable, long-lasting power. Compared with AGM batteries, these GEL units have a slower self-discharge rate, so they retain charge longer while idle and make an excellent upgrade choice. Built to handle a wide range of climates, they maintain consistent output in extreme temperatures and resist performance loss from temperature swings. The thick, non-spillable gel paste reduces the chance of leaks and corrosive fumes, and the construction is more resistant to vibration and shock—well-suited for rugged or demanding applications. Backed by Mighty Max’s reputation for quality, these GEL batteries deliver improved discharge characteristics, enhanced safety, better overall performance, and extended service life.
