I seem to have pretty good luck with batteries:
I think I've only changed four or five in all of the cars I've driven.
My 1975 Buick Century got one as a PM replacement in it's first winter.
My 1979 Fairmont, and I did that the first cold winter day after I purchased the car for $100 in late summer. (Spent $80 on the battery, even thought I didn't know if the car needed it or not.)
I purchased two batteries for my 81 Rabbit Diesel. I replaced the one in the car, and wired a second in parallel for additional capacity for starting in the winter.
I put one in my wife's 1991 Sunbird. We had that car for seven years, so that wasn't too bad.
And I've installed one in my 1987 Buick. This is the third battery for the Buick.
I typically purchase Die-Hards.
Now my 2000 Mazda, (Built in the Fall of 99) still has the factory battery, and my 98 SVT, Built 4/97 still has the factory battery. I do have a spare battery for the SVT as when I had to replace the Buick battery, I just bought a Diehard Silver and took the bad battery back to Wal-Mart for a warranty replacement. They let me get the 41-4 (IIRC) that allegedly fits the Contour. So it has been sitting on the shelf for the past year, just in case. I periodically charge it to keep it good. But, if it goes bad in the next year, free replacement during the first 24 months.
However, with how little I drive the SVT, the battery may last forever, LOL.
