To verify your RYOBI OP406 40V Lithium-Ion Rapid Charger is charging properly, observe the indicator on the charger. During charging, the LED flashes, signaling the battery is actively charging. As the battery nears full charge, the LED transitions to a solid green, indicating the final charging phase. A solid green LED signifies a fully charged battery, ready for use. If the LED flashes and indicates an error, it may be due to an issue with either the battery pack or the charger itself. Try removing and reinserting the battery. If the error persists, test with another battery. If the second battery charges, the original battery may be faulty. If multiple batteries fail to charge, the charger might need replacement. By understanding these LED behaviors, you can ensure the RYOBI OP406 is functioning correctly.
