A good mate of mine is an electrical contractor. He sourced the battery for me from one of his suppliers. I can't get him on the phone at the moment to find out which one it was, but if you need a battery let me know. The price was €85, but this was the price to him. He gets huge discounts when he wants something for himself due to the level of business he does, so it may have been a special price. I might see him later and will post again if I do. I will be away for two weeks from tomorrow lunchtime. If you need details then send me a mail before I go.
