Electrical problem
2002 Pontiac Grand Am 4 cyl Two Wheel Drive Automatic 55000 miles

My battery went dead I was told it was bad and I needed a new one. I bought a new battery and put it in and it also went dead in two days. I got my alternator tested and they said it was good and there was nothing draining on my battery, could this battery also be bad even though it is brand new?

Do you
have the same problem?

Possible, but not likely, it is most likely the alternator.

Measure voltage with DVOM at battery posts, with engine running it should be 13.5-15V.
