I guess I'll give OnStar another call and see if I can get hold of a tech person to find a part no for the battery and also where is it located. I read that on several other GM vehicles the battery is under the driver's seat...don't see it there on the H2. If it's inside the actual OnStar unit it will mean pulling at least the center console to get to it... ARGH. Too durn cold outside to mess with it now and I really hate to pay the Chev dealer the big bucks to replace it. They get big bucks just to do a scan and my old scanner only checks engine and tranny codes. As long as I run the truck every day or two...which I usually do...it seems to be OK....for now anyway.
Thanks for the info
