YES. In my opinion, one of the BEST AGM batteries on the market!
Not only do they have a high cold cranking amp but also high reserve capacity and amp hours. When cross checking other brands I found them to be higher than most (insterstate and optima included).
I put a set in my dad's boat last year and two of my buddies both have them. One of my TM batteries finally gave out this year in November. I'll be replacing them with Duracell batteries this spring from Sam's.
