Just had one of my batteries flash just the 4th light green quickly while on the charger. I unpluged it and pushed the "test" button and the 4th light just flashed green again. I put it back on the charger and it seems to be charging normally now.
What does it mean when only the 4th light flashed rapidly green? (Similar to this video, not my actual battery)
