7. Troubleshooting

Problem: The LED indicator does not light up when batteries are inserted.

• Ensure the Micro USB cable is securely connected to both the charger and the power source.
• Verify that the USB power source is active and providing 5V/1A output.
• Check if the batteries are inserted with correct polarity (+/-).
• Confirm that the batteries are Ni-MH or Ni-CD rechargeable types. Non-rechargeable batteries will not charge.
• The batteries might be completely discharged or damaged. Try charging different batteries.

Problem: Batteries are charging slowly.

• Ensure your USB power source can provide at least 1A output. Lower current USB ports (e.g., some computer USB 2.0 ports) may result in slower charging.
• Charging time varies based on battery capacity. Higher capacity batteries will take longer to charge.

Problem: LED indicator remains red after extended charging time.

• The battery might be faulty or at the end of its lifespan. Try charging a different battery.
• Ensure the battery capacity matches the expected charging time.
