Somewhere in my shop is my specific gravity tester, it has been a while. Now that you brought that up I forgot I even had one.

I kind of knew that there would be no going back but figured I would ask the question, what you said about the plates makes sense.

Al, you are correct, we got stiffed on the batteries. There are so many small things on that same list I'm getting used to saying it. Knowing all the players in this I suspect the PO had no idea what was going on, the mechanic probably charged him for OEM replacements and put in the smallest(cheapest) marine batteries he could find.
