I replaced my battery with a 48/H6 I believe from Sams Club. A bit bigger and a bit more powerful than the one I replaced because they don't sell the straight group 48 any more. As far as I can remember is almost the exact size as the original Varta. The last battery I had to use small piece of rubber hose to space out the battery bracket. I was cleaning around the battery area and found the original red plastic cover for the positive terminal on the battery. It even fits the new Duracell.
