Thanks for all the replies on Monday about changing the Duramax batteries. When I got home I had to jump it cause it was pulled up tight to the garage wall and I couldn?t get in there to work. So it fired up and I drove it out to the barn where all my tools are and shut it off. Pulled the 1st battery by the grill out no problem. On the back one it was hissing like a tea kettle. I had to remove a bracket that is above it and it was so hot I had to wear heavy gloves to touch it. Pulled the battery and it was smoking hot. I sat it in the shade for a few hours hoping it might cool down a little. About 7 pm I needed to run the old batteries back up to the auto parts store to get the core charge back and it was no longer hissing but was way too hot to touch. I was half way scared the thing might blow up on me. When I took it into the store it was hissing again and I was sure to warn the counter guys to be careful with the crazy thing. They didn?t seem to worried. When I left it was sitting right up on the counter with a half dozen customers standing around. I have had them short out before but this one was hotter than any battery I have ever seen. Even the hood of the truck to too hot to touch with a bare hand over that battery and it had been sitting inside all day.
