I purchased two green ncr 18650a protected batteries and a xtar wp2 charger. I might have changed out the batteries a couple of times, but for the most part I have been using the same battery and the other one sat parked in the charger. Did I ruin it by leaving it in the charger? It was not plugged in. I might have used the battery once for a USB charge. The voltage now reads .6 and the light goes green on the charger instead of red. Is there anything I can do besides go out and by another one?
Thanks,
Glen
