Common Boat Battery Types and Sizes: The common marine battery lingo that you will hear relates to the actual battery sizes and composition. You will hear terms like Group 24, 27, 31, and also the larger 4D or 8D sizes. The Group 24-27-31 batteries are very similar in size to the ones you find in your car.
How long do marine batteries last? I already know the answer is it depends. The type of battery, how it is used, climate, and other factors are at work I'm sure. I was thinking about replacing my 2 batteries at the end of the season after 3 years of use with no issues (I believe they are AGM, multi-purpose). My boat is in operation from April to October in the Upper Chesapeake Bay.
