Morning Tim
What Voltage are you measuring at the battery when it's fully charged not connected to the car? It should be minimum 12.5v measure then wait a couple of hours and measure again if still 12.5v minimum then the batter should be OK
If the battery is good then you have a parasitic draw now the fun begins tracing it. If charging the battery on the car only ever use the charge points in the engine bay or remove the battery from the car. Obviously easier to charge on the car. Check the car is going to sleep there is a light beside the Gear Shift that should go out after about 5 mins or so.
I would start in the Boot/Trunk at the fuse board on the righthand side, put a clamp ammeter on the Positive lead from the battery you should see the draw in Milliamps as already stated around 50/70 milliamps or below is OK anything above is Bad. So using a fuse layout chart pull 1 fuse at a time always pull a fuse check the ammeter then replace the fuse. When you pull a fuse and the Draw drops that is the circuit behind the problem, don't forget the 30g relay. Hopefully you find the culprit then the fun is finding the cause. If not then you need to go through the same process on both front Fuse boards in the front of the car in the Footwell and under the Bonnet/Hood
Hope this helps
Dave
