During the early spring here in NYC my car sat unused for most of the time due to quarantine. I was able to jump start it with my portable battery, but for the first couple of weeks I had to keep jump starting it. Currently it is starting without any problems. Thinking I needed a new battery I stopped by autozone to have the battery checked out. The guy there said I need a new alternator.
So I did some readings with a multimeter (please keep in mind I am a beginner when working on cars.)
The car sat for about 3 days and before starting it the battery read 12.5
Once started and idling it read 14
Revving the engine moved it up above 14 by a few points.
There is no battery warning light or anything like that coming on.
Is there anything else I should do to determine if I need a new alternator or battery?
It's a 2005.5 VW Jetta TDI with about 114,000 miles.
Thanks
