Operating Instructions

This section details how to use your BONAI Smart Battery Charger effectively.

1. Inserting Batteries

• Identify the correct battery type (AA, AAA, C, D, or 9V) you wish to charge.
• For AA, AAA, C, and D batteries, insert them into the adjustable charging slots, ensuring correct polarity (+ and - ends match the markings on the charger).
• For 9V batteries, insert them into the dedicated 9V battery slots at the back of the charger, ensuring proper contact with the terminals.
• Important: Only use Ni-MH or Ni-CD rechargeable batteries. Do not attempt to charge non-rechargeable batteries (e.g., Alkaline, Zinc-Carbon) as this can damage the charger and pose a safety risk.

2. Understanding the LCD Display and Indicators

The smart LCD display provides clear information about the charging process for AA/AAA/C/D batteries. For 9V batteries, an LED indicator is used.

• Charging (CHG): The battery icon on the LCD will animate or show segments filling up, indicating that the battery is currently charging.
• Fully Charged: A full battery icon will appear on the LCD, indicating that the battery has reached full capacity. For 9V batteries, the corresponding LED will turn off or change color (refer to charger's specific LED behavior).
• Discharging (DISCHG): When the discharge function is active, the LCD will display "DISCHG".
• Error: If "ERROR" is displayed, it indicates an issue such as an incorrectly installed battery, a non-rechargeable battery, or a defective battery.

3. Discharge Function

The discharge function is available for 1-4 AA, AAA, C, and D Ni-MH/Ni-CD batteries. This feature helps to eliminate memory effect and optimize battery life.

• To discharge a battery, insert it into a slot and press the dedicated discharge button. The LCD will show "DISCHG".
• Once the discharge cycle is complete, the charger will automatically switch to charging mode.
• Note: The discharge function is not available for 9V batteries.

4. Charging Time

Charging times vary depending on the battery type and capacity. As a general guide:

• AA, AAA, C, D batteries: Approximately 5 hours.
• 9V batteries: Approximately 15 hours.

Maintenance

Proper maintenance ensures the longevity and optimal performance of your BONAI Smart Battery Charger.

• Cleaning: Use a soft, dry cloth to clean the charger's exterior. Do not use liquid cleaners or abrasive materials.
• Storage: When not in use, store the charger in a cool, dry place away from direct sunlight and extreme temperatures.
• Unplugging: Always unplug the charger from the power source when it is not in use or when performing maintenance.
• Avoid Obstruction: Ensure that the ventilation openings on the charger are not blocked to prevent overheating.

Troubleshooting

If you encounter issues with your BONAI Smart Battery Charger, refer to the following common problems and solutions:

• Charger Not Powering On:
  • Ensure the power cable is securely connected to both the charger and a working 2.0A USB power adapter.
  • Verify the power adapter is plugged into a live electrical outlet.
• "ERROR" Displayed on LCD:
  • Check if the battery is inserted correctly with the positive (+) and negative (-) terminals aligned with the charger's markings.
  • Confirm that the battery is a rechargeable Ni-MH or Ni-CD type. Non-rechargeable batteries will trigger an error.
  • The battery might be defective. Try charging a different, known-good rechargeable battery.
• Batteries Not Charging / Slow Charging:
  • Ensure you are using a 2.0A power adapter. Lower amperage adapters may result in slower charging or insufficient power.
  • Clean the battery contacts on both the battery and the charger with a dry cloth to ensure good connection.
• Charger Feels Warm:
  • It is normal for the charger to become slightly warm during operation.
  • If the charger or batteries become excessively hot (exceeding 60℃), the built-in over-heat protection will automatically power off the unit. Allow it to cool down before resuming use.
