Had to look this up...hopefully this maybe helpful to others:

"MARINE CRANKING AMPS (MCA)
Batteries designed for marine use may be rated at MCA instead of CCA. The MCA rating method measures battery output at 32o F., not 0o F. A battery's MCA rating will be one-third higher than its CCA rating would be.
To compare two batteries when one has an MCA rating and the other has a CCA rating. multiply the CCA rating by 1.3 for the equivalent MCA rating. Or, multiply the MCA rating by 0.77 for the equivalent CCA rating."
