So after a few various things of trying to find what was draining the battery i finally found the tracker battery and surprise surprise it was grounding out, had to physically remove, taped wires and removed fuse.

The Mrs took the battery back and guy said he had to charge for 24hrs then leave for a day and check to see the charge, i had a bit of a go on the phone as battery was only 2 months old, anyways home from work on Friday phoned shop and the guy says you were correct battery has a faulty cell come and get a new 1, so went and got it put it on and so far its still alive, the other battery died after 2 days so hopefully all is ok

Just want to say a big thank you to all who put suggestions my way
