The alternator could function fine one day, and not the next due to a faulty voltage regulator. Some days all would be good, other days I'd have to restart the car numerous times to get the alternator kicking.
I don't think you gave bad info. The battery needed to be replaced regardless. It was the original battery from 2011. I replaced it yesterday with a Duralast H8-AGM from Autozone and I plan on getting it coded and registered today. I'll have the shop see if any other codes come up. The warning light was gone after I installed the new battery last night. Hopefully that solved it.
