CHARGING A COOL BATTERY PACK If battery pack is within normal temperature range, the red LED on charger will come on. NOTE: If the charger does not charge the battery pack under normal circumstances, return both the battery pack and charger to your nearest Ryobi Authorized Service Center for electrical check. n Charge the battery pack only with a recommended charger. n Make sure the power supply is normal household voltage, 120 volts, 60 Hz, AC only. n Connect the charger to the power supply. n Place the battery pack in the charger aligning raised rib on the battery pack with the groove in the charger. n Press down on the battery pack to be sure contacts on the battery pack engage properly with contacts in the charger. n Normally the red LED on charger will come on. This indicates the charger is in fast charging mode. n 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. n 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. n After normal usage, a minimum of 1 hour of charging time is required to fully recharge battery pack. n The battery pack will become slightly warm to the touch while charging.
