I have a two Marine Starting Batteries that I would like to change next season with Deep Cycle ones. The issue is that the CCA for a Deep Cycle Battery is generally much lower than that of a Starting Battery of the same grouping. I'd like to use a Deep Cycle Battery having the same or higher rating as the starting batteries. The Starting Batteries that I'm currently using are each rated as follows:
27M - Group Size
1000A - Marine Cranking Amps (MCA)
800A - Cold Cranking Amps (CCA)
125 - Reserve Capacity (RC) Minutes
9.5 inches x12.75 inches x6.875 inches (HxLxW)
57 lbs
The Deep Cycle Batteries are DieHard Platinum Marine Batteries having the following ratings:
31M - Group Size
1150A - Cold Cranking Amps (CCA)
205- Reserve Capacity (RC) Minutes
9.5 inches x13 inches x6.8 inches (HxLxW)
75 lbs
Questions:
Do I need to stay with the same group size that I'm currently using?
Are there any downsides to going with a battery of a different grouping albeit slightly larger and much heavier?
Will the Deep Cycle Batteries perform at optimal levels given that they would be used as replacements for the smaller Starting Batteries?
Thanks in advance for any insight on this topic.
