More Battery Questions

[Raf]

I am replacing my cranking battery. This battery serves two purposes, it starts my motor (40hp) and also runs the rear graph, bilge and nav lights. I have a separate deep cycle (that's tired as well) for the trolling motor (55pd 12v) and graph up front.

 

Should I be looking at a marine cranking battery, a combo cranking/deep cycle or just deep cycle.

 

A small 24 series deep cycle is what was in there before.

 

For the front, Deep Cycle only. 27 or 31 series? I am guessing the difference is how much reserve power I have.

You are fine with another Group 24 CRANKING battery. If you were running a trolling motor then you go with a Deep Cycle. Hopefully your TM battery lasts this year for you.
