On my original going on it's 7th year, but only 45K. This weekend, I had all 10 lights on for a few minutes with the truck off and when I went to start it, the battery barely turned it over. So I'm thinking I'll replace it now rather than be stranded in December. From what I've read in CR, the Sears Die Hard Platinum scored the best at $180. Think an OEM would be better than that?
