we are finally starting to get ice in PA so I went to charge my showdown and it is not charging. I followed the manual for long term storage, checked the fuse, and the wiring is correct. I wonder if the battery itself needs replaced since it's about 5 years old. I was also wondering if I need a battery does anyone know if I can get one at a local auto store or radioshack, or do I need to purchase one through Marcum. I want to fish this weekend but if I don't have the showdown I'm not going to waste my time
