This indicates the charger is in fast charging mode.  Red LED should remain on for approximately 1 hour then the green LED will come on. Green LED on indicates battery pack is fully charged and charger is in maintenance charge mode. Note: The green LED will remain on until the battery pack is removed from the charger or charger is disconnected from the power supply.  If both yellow and green LEDs come on, this indicates a deeply discharged or defective battery pack. Allow the battery pack to remain in the charger for 15 to 30 minutes. When the battery pack reaches normal voltage range, the red LED should come on. If the red LED does not come on after 30 minutes, this may indicate a defective battery pack and should be replaced.  After normal usage, a minimum of 1 hour of charging time is required to fully recharge battery pack.  The battery pack will become slightly warm to the touch while charging. This is normal and does not indicate a problem.  Do not place the charger and battery pack in an area of extreme heat or cold. They will work best at normal room temperature.
