Strange voltages indeed. Especially 13.6V with the engine off.
Did you try it across the battery terminals with the positive cable removed? I know that will reset some adaptations.....but it should at least give a true reading of the battery itself.
I'm suspecting an iffy alternator as well. You could put your meter across it's output wire and the casing as the engine is grounded, which is a bit easier and quicker. You could also try it on the bodyshell ground point as well just to make sure there's no strange voltage drops through the engine's ground strap.
