The battery on my 4x4 Sapphire Cosworth is only holding charge for about a week. I have had the battery drop tested (no jokes) out of the car and then in the car to see if it is being charged by the alternator. The results were that the battery is showing 13.94v when the car is off, 12.43v when running with all the screens, blowers, radio on at idle and 13.39v when at 3000rpm. If you lock the car with everything off the battery has 0.6 amps being drained from it and im told the usual is about 0.1-0.3 amps for memories etc.

I have checked that the interior lights are out and they are, any other suggestions??

Please help
