2010 Camry 99,000 miles 4cyl
Wife was sitting in parking lot idling with ac on for about 30 minutes waiting for soccer practice to end.
Turns off car for about 2 minutes and won’t turn back on.
I jumped it after the battery charged for about 5 minutes and it cranked on.
Battery is about 2 yo from Advance Auto Parts. They tested the battery and said it needs charged. They pull it charge inside for 30+ minutes. Run another diagnostic and claims excessive ripple and needs alternator.
Does this sound right? Not sure I’ve ever had a bad Toyota alternator this early
Here are the side x side print out before and after the charge.
