Boat battery question from a rookie. I have a 17 ft boat with a 40 hp Evinrude 2 stroke. I am about as new to boating as one can be, but am trying to learn. I saw that the battery near the stern is a deep cycle. Shouldn't this be a cranking battery? It's use is for the outboard and nothing else that I'm aware of. When I got the boat, the battery for the auxiliary equipment froze and cracked. The previous owner left both batteries in the boat over the winter. I bought a new deep cycle and mounted it in its place near the bow and all the auxiliary equipment then worked correctly. Now.....I've seen that some have recommended that a dual purpose cranking/ deep cycle battery be used to start the outboard. Is there a reason for this? When I saw that the battery hooked up to the outboard was a deep cycle, I was happy because I could move it to the bow and wire it into the system and use it to power my 12/24v trolling motor. I was just going to replace it with a cranking battery. Were those suggestions for a one battery boat that would use the single battery to power the outboard and accessories or should a dual purpose battery be used, even if it is only going to be used to start the outboard? Or.....should I leave well enough alone and leave the deep cycle in the stern starting the engine????? Thanks in advance and sorry for the long story, but I wanted to give as much I do as I could.
