Hi Garry, good comment. Car now running perfectly again, but old battery completely flat for a week or so and would not hold charge. However, I put a solar trickle charger on the old battery for a few days, which seems to have jolted it's memory! It now charges and holds charge again, so will keep it to use for bits and bobs around the workshop, electroplating etc, and possibly as a spare during the winter. I am told that it is easy to refurbish banners at home?
