Mighty Max ML9-12GEL 12V 9AH GEL F2 Replacement Batteries for Tas 3000 Telephone Entry System - 4 Pack

ML9-12GEL is a 12V 9AH GEL rechargeable, maintenance-free battery sold here as a 4-pack. Designed as a direct replacement compatible with the Tas 3000 telephone entry system and fitted with F2 terminals for easy installation, these GEL batteries hold charge longer than AGM types thanks to a slower self-discharge rate, making them an excellent upgrade choice. Built to perform across a wide range of climates, Mighty Max GEL cells deliver dependable power in both hot and cold conditions. The thick, non-spillable gel paste reduces the risk of leaks, acid spills and harmful fumes, and the sealed construction helps the batteries withstand vibration and shock in demanding environments. Backed by Mighty Max’s strong reputation for reliability, these GEL batteries offer improved discharge characteristics, enhanced safety, consistent performance and an extended service life.
