What do the LED lights on the charger mean?
The red LED indicates the charger is in fast charging mode. The green LED indicates the battery pack is fully charged and in trickle charge mode. If both yellow and green LEDs come on simultaneously, this indicates a deeply discharged or defective battery pack. No LED at all indicates a defective charger or battery pack. (Page 9)
