Maintenance

Proper maintenance ensures the longevity and optimal performance of your charger:

• Cleaning: Disconnect the charger from power before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or solvents.
• Storage: Store the charger in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
• Battery Care: Always use high-quality rechargeable batteries. Avoid mixing old and new batteries or different types of batteries in the same charging cycle if possible, although the charger supports mixed types.

Troubleshooting

If you encounter issues with your charger, refer to the following common problems and solutions:

• Charger not turning on: Ensure the USB cable is securely connected to both the charger and a working power source. Verify the power source is active (e.g., wall adapter is plugged in).
• Batteries not charging / Error symbol on LCD:
  • Check if the batteries are inserted correctly with the correct polarity (+/-).
  • Ensure the batteries are rechargeable (NiMH, NiCD, or Li-ion). Non-rechargeable batteries will cause an error.
  • The battery might be faulty or severely discharged. Try a different battery.
  • Clean the battery contacts and charger terminals with a dry cloth.
• Slow charging: Ensure your USB power adapter provides sufficient output (recommended 5V-2A). Lower current adapters may result in slower charging.
