CCA to AH conversion?

[saburai]

Hi Gang!
Just getting my feet wet with 12v systems... Is there a way to convert CCA to AH? Rough estimate? I've got two 880CCA Sears Diehard Platinum AGM batteries in the XJ and I'm attempting to do some power system planning...
TIA!

There's a correlation, but not necessarily a conversion. CCA is like horsepower, and AH is like the size of your gas tank.

Thanks. How do I go about figuring amp hours?

Look on Odyssey's website. Find the battery which most closely resembles your die hards. There is no formula for CCA to A/h. It would be different for each make and model of battery.
