My battery keeps going dead if I leave the car unstarted for more than 1 day.
First of all I thought the battery was fiished but I had it tested and was told that the tester showed everything OK , it just needed charging.
My second thoughts were the alternator however I do not think this is the case as if I charge the battery then do nothing apart from leave the car standing the battery still goes dead.
Last of all I thought that I would measure the drain on the battery with everything switched off, I could not seem to measure anything more significant than on any other car.
Someone told me that this could be caused by a bad earth, what is the likelyhood of this? And if it is a factor where should I be looking for this "bad connection"?

Replace the battery, one of the cells is probably dead.

I agree with dinsen, its most probably a bad cell in the battery.
However, I have once experienced something similar (not just a day, but say 3-4 days would more or less drain it)
This was (I think) caused by power-drain in the connector for the towbar.
The connectors appeared to be totally corroded - which is a common sign of leaking voltage, - and after cleaning the connector-plug , I haven't had any batteryproblems.
months before, I know the plug was in much better shape, so the accellerated speed of corrosion build-up was the tell-tale sign.
