test cca with dmm?
I think I may have gotten tricked at autozone. I bought a 34/78 optima battery. The optima website says 750 CCA, the autozone website says 750 CCA, but the products says 650 CCA. The CA is correct with all other posted values. Can I test CCA with a DMM or should I just return it? I wanted roughly 700 CCA and this was a good fit at a good price. Any ideas?
