06 6.0 Voltage issue

Hello all,

I have a new to me 06 f350 which is my first diesel. The truck has an edge programmer and I have noticed during cranking the voltage can drop down into the 9's.

I took the truck in today and had the batteries tested at Les Schwab where the batteries were purchased (They are 4 years old with a 84 month warranty)
These are their premium extreme batteries rated for 850 CCA at 0 degress and 1000 at 32 degrees. Their machine stated one battery came back at 670CCA and the other 689CCA. The mechanic stated that is within spec for being 4 years old. He then stated that my alternator was the problem. While driving home I noticed my voltage was around 13.2-13.4 for about 5 minutes and then slowly picked up and was peaking at 13.8 after about 15 minutes on the road.

I am a bit confused here as I think the batteries need to be replaced but they were flat out saying i was wrong. I don't think they want to have to prorate new batteries.

Also according to my battery charger at home which I just put on they were at 80% charge.

Thank you for your help my friends.
