I have a denix based DL 44 that I had built for me last year. The battery steadily seemed to lose its ability to hold a charge and now I get no activity out of the board. I disassembled it and I can get 6.2 V on the battery using a multimeter. I think there is power at the board, and there is continuity from the recharge port to the board. I am kind of stumped at this point as to what might be happening I’m thinking it could be a bad recharge porch as it has always been a tight fit. Does anyone know does anyone have any other things I should be checking?
