Operating Instructions: Charging the Battery
The P117 charger is designed to charge Ryobi One+ 18V Lithium Ion and NiCad batteries. The IntelliPort Technology optimizes charging for battery longevity.
- Insert Battery: Slide the Ryobi 18V battery into the charging port on the P117 charger. Ensure it clicks securely into place.
- Monitor Indicator Lights: The charger features several indicator lights to communicate the battery's status:
- Power On (Red): Indicates the charger is plugged in and receiving power.
- Temp Delay (Red Flashing): Battery temperature is too hot or too cold. Charging will begin automatically once the temperature is within an acceptable range.
- Testing (Green Flashing): The charger is analyzing the battery condition.
- Defective (Red Solid): The battery is defective and cannot be charged.
- Charging (Green Flashing): The battery is actively charging.
- Maintenance Charge (Green Solid): The battery is fully charged and the charger is maintaining its charge.
- Charged / Energy Save (Green Solid): The battery is fully charged and the charger has entered energy-saving mode.
- Charging Time: A fully depleted 4.0AH Lithium Ion battery (P108) typically charges in approximately 30 minutes. Actual charging time may vary based on battery condition and ambient temperature.
- Remove Battery: Once the "Charged / Energy Save" indicator light is solid green, the battery is fully charged. Press the release latches on the battery and slide it out of the charger.

Maintenance
- Cleaning: Keep the charger and battery clean and free of debris. Use a dry cloth to wipe surfaces. Do not use water or chemical cleaners.
- Storage: Store the charger and batteries in a cool, dry place, away from direct sunlight and extreme temperatures. For long-term storage, ensure batteries are partially charged (not fully depleted or fully charged).
- Cord Inspection: Regularly inspect the charger cord for any signs of damage. If damaged, do not use the charger.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger not powering on (no lights) | Not plugged in; faulty outlet; damaged cord. | Ensure charger is securely plugged into a working outlet. Check for cord damage. |
| Temp Delay light flashing (Red) | Battery temperature is outside optimal range. | Move battery and charger to a location with moderate temperature (e.g., 60-80°F or 15-27°C). Charging will resume automatically. |
| Defective light solid (Red) | Battery is damaged or faulty. | Remove the battery. If the light remains solid, the battery is likely defective and should be replaced. |
| Battery not charging (no green lights) | Battery not properly seated; charger malfunction. | Re-insert the battery, ensuring a secure connection. If issues persist, contact customer support. |
