Default deep cycle batteries cca's vs mca's

I have a 02 496 ho engine , was told that battery should have at least 1000 mca's . looked at the sears die hard platinum deep cycle that had 850 cca's . is there a conversion from cca's to mca's ?

From Oddyssey batteries:

Define the difference between MCA and CCA.
The marine cranking ampere (MCA) rating of a battery is very similar to the CCA rating; the only difference is that while the CCA is measured at a temperature of 0F, the MCA is measured at 32F. All other requirements are the same — the ampere draw is for 30 seconds and the end of discharge voltage in both cases is 1.20 volts per cell.


I don't think there is an exact conversion but 850 would be fine.

I would think also 850 would be plenty
