Mighty Max ML9-12GEL 12V 9AH GEL F2 Replacement Battery for CSB HR1234W - 8 Pack

ML9-12GEL is a 12V 9AH GEL rechargeable, maintenance-free battery sold as an 8-pack. These GEL cells feature a slower self-discharge rate than AGM batteries, so they hold their charge longer when left unused—making them an excellent upgrade option.

Designed to perform across a wide range of climates, Mighty Max GEL batteries maintain dependable output in extreme heat or cold and tolerate temperature swings. The batteries use a thick, non-spillable gel paste that reduces the chance of leaks and minimizes the risk of acid spills and harmful fumes.

That sealed gel construction also improves resistance to vibration and shock, making these units suitable for demanding or mobile applications. Backed by Mighty Max’s reputation for reliability, this model leverages GEL technology for superior discharge behavior, improved safety, consistent performance, and an extended service life.
