The more I read, sometimes the more confused I get....
I'm looking to get 3 new batteries this spring: 1 starter battery, and 2 batteries for a 24v setup for trolling. I think I've finally been educated regarding what kind of batteries to get, however now I need to know what size.
Starter: From what I understand, for the starter battery cranking amps are the important factor. However, is it possible to get a battery with too much power? For example, is a group 27 with 900 amps too large for my motor which is a 1996 Johnson 115 V4? Is larger always better? Is a marine battery required for a starting battery, or any (i.e. automotive) battery with suitable cranking amps ok? Are there specs listed for my motor somewhere? Is the group size an important factor, or only the cranking amps?
Accessory/ Trolling: Similarily, I have been advised to get deep cycle trolling batteries with a large reserve capacity of 190-200. Does size/ group matter? Do cranking amps matter for a trolling/ accessory battery?
Any advice or direction to a previous forum thread or website would be greatly appreciated.
