So, I took it in again and the head mechanic said it's nothing to worry about, that it was probably always happening and I just never noticed it. He said that the battery is 12V, and the alternator adds the voltage on top of that. He said it is normal for the voltage to fluctuate between 13-14V when the car needs a little more electrical power. He said that the engine idles a little higher now and then to give the alternator some extra juice.

He did say that it is a problem if it goes lower than 13V; usually, mine only drops to about 13.5V.

Any comments on his verdict?
