Battery size

[seafish]

That's my opinion. The drivers side is the one to keep.



You can move to single battery, but my suggestion is to get one that has at least the same CCA as the sum of the factory batteries. That would be 1300 amp, I believe.



But it will vary by user. Users in perpetually warm areas may only need one 750 CCA battery. Users running thinner oil won't need as big a battery.



I have always thought that oil viscosity is the main factor in determining your battery size. If you're cranking 15w-40, particularly in cold weather, you need a TON of energy. If you're running 5w-40 synthetic, you don't need as much energy.



Having said that, my opinion has always been "run the biggest battery that will fit". But then, I run 15w-40 and I live in a cold climate.

Well, 1150 CCA with a 2 hour reserve for the Diehard Platinum Marine 31 is pretty damn close to the 1300 of both stock batteries. I also live in a temperate climate, it rarely goes below freezing, and never below 26*F. I am not eager to drop a battery and porobaby won't, BUT it is an interesting idea to free up all that nice space for an engine compartment mounted compressor and or extra cooloant/fuel filters (more toys in other words... :-laf)
