Batteries for 75hp Honda

[Renny1]

I am looking to replace my batteries, I have a duel battery set up for a Honda 75hp. The current batteries are of two different CCA, 650 and 585. Can anyone point me in the right dirrection as to the CCA that will be adequate for this motor?

Has the 650 been doing the job???

Yes the 650 has been doing the job, but when alternating to the 585, it was starting just as well. They are both over 4 years old and getting a little lazy.

I was recently looking online at various batteries and came across these type of new AGM batteries for the Marine environment, this one below is used for starting only (Dark Grey Case) but does also come in Deep Cycle format (Light Grey Case)
