Possibly a hard one to call, without someone looking at it, and physically checking it with a meter. I think you could be looking at a duff cell in the battery. How old is the battery? Is it still under guarantee? If it's under guarantee, you can get it checked out free of charge, and replaced for nothing. If the guarantee has run out, they will still check it free of charge, and ask you to buy a new battery from them. Fair's fair I suppose. Running it without any electrics on, is not a real good guide to the state of the battery. The tool that you need is called a Heavy Dischartge Tester. This is placed across the whole of the twelve volts, and held in position for a few seconds. If it takes the load that the Heavy Discharge Tester is subjecting it to, then you can look somewhere else. I hope this helps you a bit.

got the problem sorted turned to to be a short coming from the switch that operates the roof unbeknown to me the the roof motor was running and that was what flattend the battery lucky that it didnt burst into flames
