I bought a Gyrfalcon All-44 from IMR in October and until recently it has worked flawlessly. This past week I noticed that one slot (second from the left if that matters) didn't charge one of my VTC5As all the way. I put the battery in at around 3.8 volts along with a couple of others and the next morning two of the three cells were fully charged but one showed it was still charging at 4.0 volts. I thought maybe it was crooked or something so I took it out and put it back in. Later that day it was still at 4.0 volts. I examined the battery again and there is no visible damage. This cell is one of four that I bought in December and all have performed well. I put the cell in a different slot and it charged right up to 4.2 volts. I have since put different VTC5As and some 25Rs in that slot and am getting the same result the majority of the time. Usually the cells will get between 3.8 and 4.0 and stop. Any suggestions for someone who isn't the most technologically advanced person?
