I was fishing today and my unit quit because of low voltage. Only about 6 hours. I seldom fish that long, and have never had it completely drain the battery before (except when the original battery failed). It seems to charge OK, the light turns from red to green overnight, and the battery is on its 2nd full season.
What's your experience? I know guys say they are supposed to go 12 hours or so on a charge. I don't use backlight, and not sure what I could be doing to be drawing the battery down so fast, unless this battery is starting to fail too.
