5. Setup
Follow these steps to set up your MiBOXER Smart Battery Charger:
- Unpack the charger and all accessories from the box.
- Connect the provided power adapter to the DC 12V/3A input port on the back of the charger.
- Plug the power adapter into a standard wall outlet. The LCD display will illuminate.
- Carefully insert rechargeable batteries into the charging slots, ensuring correct polarity (positive (+) and negative (-) terminals align with the markings in the slots). The charger will automatically detect the battery type for Li-ion (4.2V) and Ni-MH/Ni-Cd (1.48V) batteries.

6. Operation
Operating the MiBOXER Smart Battery Charger is intuitive:
6.1. Automatic Battery Detection
For Li-ion (4.2V) and Ni-MH/Ni-Cd (1.48V) batteries, the charger will automatically detect the battery type and begin charging. The LCD will display relevant charging information.
6.2. Manual Battery Type Selection
For Li-ion (4.35V) and LiFePO4 (3.6V) batteries, you need to manually select the battery type:
- Insert the battery into the desired slot.
- Press the SLOT button to select the corresponding channel (C1-C8).
- Press and hold the MODE button to cycle through the battery types (Li-ion 4.35V, LiFePO4 3.6V). Release the button when the correct type is displayed.
- The charger will then begin charging with the selected parameters.
6.3. Understanding the LCD Display
The LCD provides detailed information for each charging slot:
- Voltage (V): Current voltage of the battery.
- Current (A/mA): Charging current being applied.
- Charging Time: Duration of the current charging cycle.
- Mode: Indicates the charging mode (e.g., CC for Constant Current, CV for Constant Voltage).
- Battery Type: Displays the detected or selected battery chemistry (e.g., Li-ion, Ni-MH, LiFePO4).
- Internal Resistance: Shows the internal resistance of the battery.
- Capacity (mAh): Displays the accumulated charged capacity.
- Percentage (%): Indicates the approximate charge level.

8. Troubleshooting
If you encounter issues with your MiBOXER Smart Battery Charger, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| LCD shows error symbol / Charging stops unexpectedly | Battery inserted with reversed polarity. Battery is short-circuited. Battery is damaged. | Ensure battery polarity is correct. Remove the battery and check for external damage or shorting. Replace the damaged battery. |
| Battery not charging (no display activity) | Charger not powered. Battery is severely over-discharged. Incorrect battery type selected (for manual types). | Check power adapter connection and wall outlet. The charger may attempt to activate over-discharged batteries; allow time. If activation fails, the battery may be unrecoverable. Ensure correct battery type is manually selected for Li-ion (4.35V) or LiFePO4. |
| LCD backlight dims quickly | Normal operation. | The LCD backlight is designed to dim after 1 minute of inactivity to save power. This is not a fault. |
