My bettery recently went dead. I couldn't believe it. I had to get a friend to jump it to start. At the dealership, for a check engine light one week later, the tech just looked at the window on top and said, "looks okay now."
From what I remember a good battery will read 13.4V (or so). A battery that needs replacing will measure 11.8V.( or so)
Never heard of an Optima Yellow Top before. </div></BLOCKQUOTE>
That tech should be fired for incompetence. Just because the "eye" shows green (they don't anymore, ACDelco took it out it was so misleading) doesn't mean the battery would pass a load test. The proper procedure would be a Midtronics battery tester sequence. Insist upon a load test and ask to see the results, it comes as a printout showing the various readings under load.

I had them run the battery load test at the dealership, because my poor car will be there for a few days. The battery was low and they are replacing it. I wonder if running my off road lights for a few miles finished it off.
They require 35A and I'm not sure about the electrical system of the H2. What is Current output of the stock alternator? I would think that running at 1500 RPM it would provide enough charge for a few miles.
Anyway, thanks for the tips.
