The 7 year old Bosch battery in my E 300 D just went bad. Lost a cell. I carried it back to Pep Boys and said, I need another just like this. The warranty was 8 years, so I got $14 credit, BUT the battery was $179. I bought the old one 7 years ago for $99.

I think I have it figured out. The parts stores SAY they install batteries free, but if you go to Walmart or a battery outlet, the prices will be 25 to 40 percent cheaper, so in fact they are charging for the free installation.
