7. Discharge Function
The BONAI charger is equipped with a unique discharge function. To activate:
- Insert the rechargeable batteries into the desired slots.
- Press the discharge button located on the left side of the charger. The charger will enter discharge mode.
This function is beneficial for Ni-MH/Ni-CD batteries as it can help eliminate the "memory effect," which can reduce battery capacity over time. Discharging batteries periodically before recharging can help prolong their overall lifespan.
8. Maintenance
- Cleaning: Disconnect the charger from power before cleaning. Use a soft, dry cloth to wipe the surface. Do not use abrasive cleaners or solvents.
- Storage: Store the charger in a cool, dry place away from direct sunlight and extreme temperatures.

9. Troubleshooting
- Batteries not charging:
- Ensure the power adapter is securely connected to both the charger and the wall outlet.
- Verify that batteries are inserted with correct polarity (+/-).
- Check if the batteries are rechargeable Ni-MH/Ni-CD/Li-ion. Non-rechargeable batteries will not charge.
- Some batteries may be too old or damaged to accept a charge. Try different batteries.
- LCD screen not displaying:
- Ensure the charger is properly connected to a power source.
- If the issue persists, contact customer support.
- Charger feels warm during operation:
