Very Slow Cranking

I have a 08 6.4 350. In the mornings when I start it up, it acts like it barely wants to crank. It cranks super slow, like the battery is low. If it sits for a while in the middle of the day it also acts like it barely wants to crank over. Checked both batteries, they are good, and they are less than 10 months old, motor craft batteries. Could it be the alternator, cables, or something else? Just had the dealership checking out the batteries and charging system, they say all is OK. They said they cannot take the batteries out separately and test them. It just seems like batteries, where else should i check?

Do you have anything that could be drawing a load on your batteries when you let it sit? Check your cable connections for tightness or corrosion same thing with your starter check to make sure the connections are tight. Just a few thoughts for you.

Thanks fro the help guys. I talked to a friend who retired from a Ford garage after 35 years as a Master mechanic. He told me it probably was the starter and said that I should have them do the replacement. $650 later the job is done and it seems to run great again. $429 for the part, the rest labor/ tax. I guess this is the going rate for the part and labor? Was it that hard to change? Opinions welcome.

right off the bat any mechanic who says he can't test the batteries separately I would run as fast as I could go away. and I would call him dumb f### to his face. generally if you have some basic skills or a buddy with a small metal lathe you can totally rebuild a starter for less than 50 bucks
