I was having starting problems about 2 week ago and I had a friend who owns a shop check the battery with his Interstate checker. It turns out that my battery was reading just below the good range and only putting out 400 cca's. I took it to the dealership to get it checked out and replaced and they said that it read good on their checker. Yesterday as I was leaving work the truck would not start at all. I had my friend replace the battery with an Interstate Mega-Tron Plus rated @ 800 cca actually reading 1050 cca's. I'll head to the dealership on Thursday with the bad battery to try to get them to pay for the battery. I know they probably wont pay for anything but its worth a try.
