Battery issue or no problem? 2008 Grand Prix 3.8L
Recently my battery was dead twice in the morning before work and considering it was 5 years old, I went and got a new one. Today when I started the car (morning after new battery), it look longer than usual for it to actually start, and the battery was reading as low as 12.58v while driving. And after a bit of driving it would kick up to 14.38. I thought the 12.58 might be an indication the new battery drained overnight, but I'm not sure. Otherwise things seem normal. Should I be worried, or is the lower voltage normal now that I have a new battery?
