Re: How many MCA reccomended for my Merc?
Thanks Fun Times, that's exactly what I needed to know. My 810 MCA batteries will be just fine.
1nebelO....I had an Optima in my previous boat, it was in the boat when I bought it, had sat there all winter encased in ice. When I got the boat home I pulled it out, cleaned it up and threw it on charge just to check the condition of it, and needed almost no charge at all. I used that battery for the next 5 years and it never ever gave me one single problem and in winter when I would periodically throw it on the charger it wouldn't need any charge at all, even after sitting for 3 weeks to a month at a time.
I went to price them out and they are $260 a piece!!! The reserve on them is low at 50 amp hrs. I got 2 Deka Group 27's 810 MCA and 175 amp hrs each for $120 a piece. I didn't want to drop $500+ and have that little of a reserve. I need the bigger batteries with more reserve capacity. But those Optimas are tough, strong, good batteries.
