Well, it is time for a battery change on the '06 340 Sundancer, and no complaints - got 7 years out of the last ones. When I changed out the originals I just took one from the boat with me and went to Interstate and said "I need 4, just like this one", and this turned out to be their 27M-XMD.
Checked the Owners Manual and it says the Recommended is Group 31; CCA:800, Reserve:200. So am thinking of upgrading from Group 27's to Group 31's. Mostly what I have found is that Group 31's are AGM instead of Flooded/wet cell.
Just wondering if my Charger will notice any difference or if I need to change the setting? I don't know what charger I have and it looks like a pain to get to - I can see it through the little window in the "cave". Or just go back with Group 27's?
