batteries
Most folks use the marine deep cycle batteries which is the best. it allows the battery to be drained and recharged many times. A standard car battery cannot take this and will not last long as one post indicated as it is designed to have a full constant charge. Yes there are differneces in batteries. Selection of standard versus gel batteries is you choice but gel batteries have a tendancy to last longer and cost more.If you take your batteries out to store during the winter, put them on a board and not directly on the ground particulay concrete as it will drain a batterey. I am not a scientist but I have experienced this so often that I thought this needed to be past on.Crazy Dave Condon
