Just came back from a week in Canada. I went up with a new everlast deep cycle marine battery. I used it hard all day and charged it every night when we got back. It worked just fine.
My buddies came up with new car batteries they got from NAPA. They also used them hard all day and came home and charged them in the evening. They worked just fine, too.
It may be because they were all new batteries, and the story may change as the batteries get older, but the bottom line for our trip was that all of the batteries we had worked just fine and they all lasted plenty long enough to suit our purposes. Maybe we were just lucky :-)
