2) SOMETHING is drawing the battery down while the car is off. Insert an ammeter in line with the battery (does not matter, positive or negative side) and see what current you have flowing.
You should see well under 1/2 amp of draw. In fact, it should be less than .1 amp draw - most cheap meters won't be able to even measure the draw! Tell you what, if you can insert a tail light bulb in series between the battery and the + or - cable, if the light lights up, you have considerable draw!
But my money is on the battery - and I don't care what the "Test" shows.
How old is this "good" battery?
Yea, Exactly what the Pizza Guy said. My original battery tested fine but my spoiler would go up when I started the car. The guys on here told me my battery was bad and I found that hard to believe but they were right. If you have an original battery it is due for replacement.
