Based upon my interaction with a AAA battery guy, I would agree.
I had a AAA battery in my daily driver. It lasted 2 years. I got it replaced under warranty. The replacement battery also died in short order. In the meantime, I had already gone through the car looking for parasitic draw, etc.
So at the 2nd battery failure, I once again called AAA as the battery should still have been under warranty. He hooked his equipment up to the car (while idling) and told me the alternator wasn't working, so all he was willing to do was give me a jump start. No replacement battery.
However, like you I had also checked the car while running, and it was putting out 14+ volts at idle. So I decided to go buy a Costco battery instead as a replacement. That was about 4 years ago. Still running with the same Interstate battery from Costco. Still haven't touched the alternator.
