Guess I don't have the magic touch for posting tables... My post on the above subject should read, left to right, line (a) for amp hours, 255, 225, 220 , on line (f) for costs, data should be 0.31, 0.33 and 0.57. Also, I should have mentioned in my post, that using the above cost figures, you can get a rough estimate of daily battery costs for providing dc current: at a typical 150 amp hours daily, the battery cost is about .32 cents (from line (f) or $.0032 times 150 or about $.50 daily. That assumes enough use that your battery doesn't sit around unused for years and die of "old age". Rob Brueckner Hatteras Yachtfisherman
