Anyone ever ran an Odyssey AGM? Just curious how good they are. Looking at a 31M-PC2150ST-M. It has 1,150 CCA, 1,370 MCA, and 205 minutes RC at 25 amps. Design life is 12 years and Typical service life is 6 to 8 years. Thats what they advertise anyway. They cost about $400 but if the service life is true, it will be worth it. Im running a 2014 250 Pro XS and currently run a 31 Optima Yellow top. 900 CCA and 155 RC. Its fine for now but it dont turn over very fast first thing in the morning on a crisp morning.
