4. Setup and Connection
Follow these steps to safely connect the charger to your battery:
- Prepare the Battery: Ensure the battery terminals are clean and free of corrosion.
- Connect Battery Clamps:
- Connect the red positive (+) clamp to the positive (+) terminal of the battery.
- Connect the black negative (-) clamp to the negative (-) terminal of the battery. If charging a battery installed in a vehicle, connect the black clamp to a metal part of the vehicle chassis away from the battery and fuel line.
- Connect to Power: Plug the charger's power cord into a standard AC (100-240V) power outlet. The charger will power on and display the current battery status.

5. Operating Modes
The VEVOR Smart Battery Charger offers four distinct operating modes to suit various battery needs:
Image: A visual representation of the four selectable modes: Charging, Maintain, Desulfation (Restoring Aging Batteries), and Force Mode (Manually begin charging batteries below 1V).
5.1 Charging Mode
This is the primary mode for charging depleted batteries. The charger automatically detects 6V, 12V, or 24V batteries and employs a 7-level intelligent charging process. Once the battery is fully charged, it automatically switches to trickle charging.
- Automatic Detection: Automatically identifies 6V, 12V, or 24V battery systems.
- Manual Selection: Allows manual selection of battery type (AGM/Lead, LiFePO4, Lithium) and charging current (AUTO, 5A, 10A, 20A).
- 7-Level Intelligent Charging: Optimizes the charging process for efficiency and battery longevity.
5.2 Maintain Mode
Designed for long-term battery maintenance, this mode sustains the charge with a lower current, preventing self-discharge and keeping the battery at optimal capacity without overcharging.
5.3 Desulfation Mode (Repair)
This mode uses pulse repair functionality to help restore sulfated or deeply discharged lead-acid batteries, potentially extending their lifespan and improving performance.
5.4 Supply Mode (Force Mode)
This mode allows manual initiation of charging for batteries with very low voltages (as low as 1V) that might not be detected by the automatic charging mode. Use with caution and monitor the battery.

6. Charging Process
After connecting the charger as described in Section 4:
- Select Battery Type: Use the "BATTERY TYPE" button to cycle through AGM/Lead, LiFePO4, and Lithium options until the correct type for your battery is selected.
- Select Voltage: Use the "VOLTS" button to select the appropriate voltage (AUTO, 6V, 12V, 24V). For most applications, "AUTO" is sufficient.
- Select Current: Use the "AMPS" button to select the desired charging current (AUTO, 5A, 10A, 20A). Refer to your battery's specifications for recommended charging rates.
- Start Charging: Press the "START/PAUSE" button to begin the charging process. The LCD display will show real-time charging status.
- Monitor Progress: The charger will automatically stop charging when the battery is full and switch to a maintenance charge if applicable.
- Disconnect: Once charging is complete, first unplug the charger from the AC power outlet, then disconnect the negative (black) clamp, followed by the positive (red) clamp.
6.1 Reference for Charging Time
The following table provides theoretical charging times for various battery capacities. Actual times may vary based on battery condition and ambient temperature.

7. Maintenance
To ensure the longevity and optimal performance of your VEVOR Smart Battery Charger:
- Cleaning: Wipe the charger casing with a dry, soft cloth. Do not use abrasive cleaners or solvents.
- Storage: Store the charger in a cool, dry place when not in use. Keep cables neatly coiled.
- Inspection: Periodically inspect the cables and clamps for any signs of damage, wear, or corrosion. Replace if necessary.
- Ventilation: Ensure the charger's ventilation openings are clear of obstructions during operation to prevent overheating.
8. Troubleshooting
If you encounter issues with your charger, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger does not power on. | No AC power; faulty power cord. | Check power outlet and connections. Ensure power cord is not damaged. |
| Charger displays an error code or does not start charging. | Incorrect battery connection (reverse polarity); battery voltage too low; incorrect mode selected. | Verify correct polarity of clamps. Use "Supply Mode" for very low voltage batteries. Ensure correct battery type and voltage are selected. |
| Charger gets hot during operation. | Normal operation; obstructed ventilation. | Some heat is normal. Ensure ventilation openings are clear. If excessively hot, disconnect and allow to cool. |
| Charging takes too long. | Battery capacity is large; low charging current selected; battery is deeply discharged. | Increase charging current if battery allows. Refer to charging time table. |
