I hope someone can give me some advice on this issue. I have had my battery plugged into the Optimate 3 over the winter but when I tried to start it a few weeks ago the battery was flat (pretty new Banner). The green light was displayed on the Optimate so nothing amiss as far as the optimate was concerned (assuming it was functioning correctly). I used jump leads on the 7 went for a blat to charge the battery , put it away for a few more weeks but when I went to start it today whilst the battery was not flat it did not have enough juice to start so back to the jump leads. The optimate again was showing the green light. Something is clearly not right here, is the optimate (also pretty new like the battery) failing in its task? Any thoughts would be appreciated.
Thanks
Jan
