Mighty Max ML12-12GEL 12V 12AH GEL F2 Replacement for Teledyne Big Beam S1210 — Pack of 3

ML12-12GEL is a 12V 12AH GEL rechargeable, maintenance-free battery — sold as a pack of 3. Equipped with F2 terminals and designed as a replacement for the Teledyne Big Beam S1210, this Mighty Max battery delivers dependable, long-lasting power.

Its GEL construction features a thick, non-spillable gel paste that reduces the chance of leaks and harmful fumes while improving safety for demanding installations. Compared with AGM batteries, the ML12-12GEL exhibits a slower self-discharge rate, so it retains charge longer during periods of non-use.

It’s engineered to withstand temperature extremes and perform reliably across a wide climate range, maintaining stable output in both hot summers and cold winters. The robust gel design also resists vibration and shock, making it suitable for rugged environments.

Backed by Mighty Max’s reputation for quality, this model leverages advanced GEL technology for superior discharge characteristics, enhanced safety, improved performance, and extended service life.
