Do i really need a deep cycle or marine battery?
Because of the type and frequency of use of a battery in such a situation, a deep-cycle marine battery is preferable. It goes through repeated deep discharges and re-charges, and that’s murder on batteries. An automobile battery is maintained at a high rate, unlike a marine battery – or batteries for riding mowers and such machines. But put an automotive battery in service elsewhere, and the thing may not last an entire season, let alone two or three. Deep-cycle batteries are designed precisely for frequent discharge-recharges. Plus, you don’t need a great big, heavy automotive battery. As you surely know, a 14-footer does not have an unlimited amount of space or load capacity…the smaller, lighter marine battery is all you need.
