Re: CCA - Cold Cranking Amps question
By the OPs original post I am assuming we are talking in simple term, no conversions or temp sensors.
I am just posting for the benefit of the OP. I have cooked alts and destroyed brand new batteries by Willie nilly battery swapping. And I am not talking about huge banks. My experience has mostly been in diesel trucks and tractors.
But everybody can judge their own ability and research their application... or you can just follow the Manufacturer suggestions.
