As some of you have read, my 2004 has 220k on it and had the original battery, until this morning. She seemed really cranky about turning over this morning. I had it tested a couple days ago. The original battery was rated 680CCA and according to the machine it was only putting out 410 (at 50 degrees). I was worried about the coming cold mornings. It barely started this morning and it was 25 degrees out.

Oh well, it would have been ten years old in July so I think I got my money's worth out of it. The new one has 800cca at 0 degrees so hopefully i will have no more issues.
