All of my tests indicated it was OK, their test showed the cranking amps were only 150 and should have been 750 amps, I got a new battery as this one was under warranty.
As for a possible drain, I have never heard of one draining a battery this quickly, but if you can use a digital ammeter you can disconnect typically the negative lead on the battery and insert the meter and see if you have current flow. If you have a significant flow (above 200 ma ?) then you may need to start pulling fuses one at a time to see what is staying on.
IMHO, I really think you have a bad battery.
Great advise from villagetinker. My sister's car had this problem once. The trunk light was staying on. You can look for obvious things like that. Check your done lights, etc. If you can't tell if trunk light stays on, you could remove the bulbs and see if there is any improvement. Another idea, you could put you iphone video camera on and close it in the trunk.
