Please remember that I am a first time boater and boat owner before you laugh too hard. This past weekend Misfit was nice enough to put my fish finder on for me. I just stood back and watched the master at work. Well anyways we (I really mean he but we sounds better ) got it all set up and we hooked it up to his battery and boy does it look purdy. I looked at his battery so now I know the one I think I will buy. My question is. Is a marine battery just like a car battery? Will it be ok if it is not charged or used for an extended amount of time? Like over the winter, or over the course of a couple of weeks? I know I won't get to fish as much as I want to so it won't be charged and ran down all that often. Do I need to keep it charging all the time? Do I need to completely drain the battery before I charge it or can I just use it and charge it when I get back? By the way my boat is stored in a garage that is detatched with no electric hook ups or heat. Do I need to store my battery and fish finder in the house over the winter or will they be ok to be out in the garage? Thanks everyone.
