Q: How to determine a defective battery or charger?

If the charger detects a problem, LED Indicator 2 will flash red. Reinsert the battery pack. If LED Indicator 2 flashes red again, try a different battery pack. If the second battery pack charges normally, dispose of the faulty battery pack (please refer to the instructions in the battery pack manual). If a different battery pack cannot solve the problem, unplug the charger and wait for LED Indicator 2 to go out. Then reconnect the plug to the power supply. If the LED on the charger still displays defective, the charger may be defective. Was this helpful?
