changing the battery wont cause it to run rough.

Need more info. car wont start isn't enough.

does it crank over?
does the tach move?
did you check for codes? If so are there any?

I wouldnt rely on the tool telling you charging volt, I would check the battery with volt meter while the car is running. 10 minutes isn't enough to drain the battery down so there is still something else going on with the car besides the battery.
