I have the smaller interstate batter in my car. It was installed January 2000, but it just won't turn over the engine if it is below 25F out. But if I use the block heater, I don't have any probs.

Maybe that is why when I ran the radio in the yard for about 20 mins this summer, I couldn't get the car to start! Not enough capacity, but plenty of CCA's (new it was 850, I had it tested a month ago and it tested at 750, not bad for a almost six year old battery. It was only warranteed for 72 months.)
