I just bought the black and decker string trimmer 20V Max this morning. Went to charge the battery, and the red light on the charger flashed and did this for an hour. What does this mean?
When the light is solid red, the batteries are charging. A flashing red LED light indicates that the charger detects abnormal batteries or the battery temperature is abnormal. When the light is a solid green, the batteries have completed their charge.
