I'm new to the forum, so no one will recognize the name. I did some extensive research concerning batteries, and there is so much 'information' out there, some good, most is supposition rather than fact. I ended up going with a DEKA group, they make MANY,MANY different sizes and use a variety of materials. they specialize in deep cycle batteries, and they are indeed used for many, many things. the Interstate deepcycle/marine battery is actually a hybrid of a true deep cycle and a starting type battery. Expect cost to mirror quality, however, if you are buying 3,4, or 5 batteries (mine uses 6) then an industrial supplier normally would be more than happy to sell them to you at a large discount from retail.
