Something is draining your battery thats for sure.. disconnect 1 battery terminal and use a multimeter to get a current reading with the ignition off. This will tell you how much current you are using with the ignition off.. not sure on what a 'good' reading would be but suspect under 3 amps
 If that checks out fine then chances are its your alternator Have you measured battery terminal voltage with the engine running? If it reads 12.5v then check the alternator output terminal 'b' (+ve); measure the brown insulated terminal with 10mm nut to earth.. Should be 13.0 - 15.9v if not, its shagged

You can try disconnecting the fusible links, in the little black box near the battery.
This will prob stop the battery dying. Then use the multimeter on the terminals to see where the current is being drawn from. One thing for sure is... Its only a simple thing thats causing the problem. Its finding it thats the pain.

I'd suggest obtaining the current being drawn from the battery while the car isn't running. Put a meter between the battery + and the terminal connector.
The reading should be pretty low, almost nothing really. Take out each fuse one by one and see if the reading changes. If it does, see what the fuse is for and there you have your fault? If you have any audio amps, maybe one of those is running all the time? I had that problem on a car once, battery lasted a few hours then dead. Just a thought.

Thanks for everyone's help, found the problem, apparently it's something to do with the starter motor, luckily I got a spare one from eBay a few months ago so I'll change it over and see what happens.

How did you narrow it down to that. That seems like an odd problem to have as a battery drain fault. Hope the new motor cures your problem
