I have a promariner dual bank prosport 8, just over a year and a half old. When I plug it in, the red charging light comes on , however the green power light no longer comes on at all. It seems to be charging, however I am concerned and want to make sure it is working right. On my other promariner, both the red and green light come on when plugged in. Then the red light goes out after a few hours of charging, while the green continues to stay on. I normally plug them in right after coming if from the lake, then unplug them the next day. I never leave them on more than overnight. If I am not fishing for a few weeks, I will plug them in for a few hours about once a week, to keep them topped off. I will call promariner tomorrow, they were already closed when I tried this evening. Anyone have any thoughts on it?
