I'm going to get rid of my 2yo Kirkland group 65 batteries (850 cca) because they are already corroding things. Looking to do the $50 isolator and would like to know what you folks think I should go with. I have room for two group 65s but they are on opposite fender wells. I could pretty easily get the group 34ms to fit on one side cleaning up a few long cable runs. I was under the impression the marine battery was a deep cycle, but after looking at the specs, I can't see where they are any different than the auto group 65. Can anyone tell me different? Should I go with two 65s or one?
Here are the batteries I'm talking about. I'm not running anything out of the ordinary like a fridge yet, but I'd like to down the road.
