I noticed that one of my 14.8 volt Li-on batteries seems to have lost is power. It was powering a 12 volt bilge fan that I have rigged up on a flat car to blow leaves off of the track. Yesterday, while operating said device, the fan suddenly stopped. I figured that the battery ran out of juice. So I placed it on the charger, but the green light of the charger stayed green, instead of going red for the charging mode. I checked the voltage this morning with a meter, and it read 16.8 volts. Somewhat higher than the batteries original rating. Then I hooked it up to the fan and nothing happened. Only a slight turn of the blades each time I switched on the fan, then nothing. These batteries have the PCB protection circuit board to gaurd against over discharging. Or that's what I thought it was supposed to do.
Can anyone enlighten me here?
