Ok so Friday I decided to head out to Hoover for maybe some eye action or maybe even some summer time crappie action. I got out on the water and of course the outboard motor wouldn't start. That's a whole different story. When I first got out on the water I checked the batter power and it said that it was 2/3's full. That can't be because I had charged the battery and left it sitting in the house until Friday morning when I went to leave. My question is could I have done something to the battery to where it won't fully charge now? When I charge it the battery charger says that it is done charging. I wonder if the charger is messed up. The only thing I have done to the battery was the first couple of times that I used it I didn't let it drain completely. I would use it to cruise around a little and then I would charge it. Could this have caused it to not fully charge now? The battery I have is an Everstart Deep cycle Marine trolling battery from Walmart. Thanks everyone.
