Its about time for new batteries in my boat and would like to put in AGMs. Has anyone used the Duracell Platinum from Batteries + Bulbs? They are running 15% off right now so can get a pretty good deal. This is going to be used as a dual purpose battery, cranking for 200hp ProXs and for electronics, Helix 10 and an 858 HD and occasional live well use. Looking at the group 31. Is that overkill or should I go for the group 27? Thanks for any help!
