Mighty Max ML9-12GEL 12V 9AH GEL F2 Replacement Battery for Humminbird GCBK - 8 Pack

ML9-12GEL is a 12V 9AH GEL rechargeable, maintenance-free battery sold in an 8-pack. Compared with AGM batteries, these GEL cells exhibit a slower self-discharge rate, so they retain charge longer in storage and make a reliable upgrade choice. They are engineered to provide steady power across a broad range of temperatures, maintaining performance in both high heat and cold conditions.

The design uses a thick, non-spillable gel paste that reduces the chance of acid leaks and harmful fumes, and the construction resists vibration and shock for demanding applications. Backed by Mighty Max’s reputation for dependable products, this GEL technology delivers superior discharge characteristics, improved safety, better performance, and a longer service life.
