    I read somewhere it does because of more space between the Plates. I'm not sure if this is true or not. Any thoughts?

    My thoughts are, I don't know what you're talking about? What's a "Batter CA" and for that matter, what are these "plates" that have more space between them?

    I really dont see any connection between Cranking Amps and Battery Life.

    Sorry I meant battery and cranking amps. It was a typo.

    I just don't understand why 2 batteries of the same group size have different CA ratings. Bigger plates? More space? I googled it and didn't come up with much.

    Only thing I found was that higher CA batteries don't last as long...but that may be bunk...which is why I posted this thread.

    IMO it all depends on where you live. If you live up North, you want the battery with the highest CCA. In the South or out West where it is hot, buying a battery that is 2x or x the factory required CCA is throwing your money away as it not needed, and batteries last about 2/3 of the life of batteries up north, due to the heat. Personally, I have always bought the middle of the road battery from Walmart. They replace them for free in the first 2 years. Unless you have a booming stereo or other special need, no reason to buy a $150 red top IMO.

    Here is a good primer I found about 20 years ago
