6. Operating Instructions
- Automatic Detection: Once connected to the battery and power, the charger will automatically detect the battery type and voltage. The display will show the current battery voltage, ambient temperature, and charging status.
- Mode Selection: Press the "MODE SELECTION" button to cycle through the available charging modes:
- CAR: For standard 12V car batteries (Lead-Acid, AGM, Gel).
- AGM: Specifically for AGM batteries.
- MOTO: For 12V motorcycle batteries.
- LiFePO4: For 12V Lithium Iron Phosphate batteries.
- REPAIR: For desulfation and repair of lead-acid batteries only. Do NOT use this mode for LiFePO4 batteries.
- Charging Process: The charger will begin charging automatically after mode selection. The display will show the charging progress, voltage, and current. The built-in fan will cycle on and off during active charging to dissipate heat. The presence of fan noise indicates active charging.
- Completion: The charger will automatically stop charging when the battery is fully charged and switch to maintenance mode. The display will indicate "FUL" or 100% charge.
- Disconnecting: First, unplug the AC power cord from the outlet. Then, disconnect the negative (-) black clamp, followed by the positive (+) red clamp.

8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger does not turn on. | No AC power; faulty outlet; damaged power cord. | Check AC power connection and outlet. Inspect power cord for damage. |
| Charger connected but not charging (no fan noise). | Incorrect battery connection; battery too deeply discharged; incorrect mode selected. | Verify correct polarity of clamps. For very low batteries, try a different charger or consult a professional. Ensure correct mode is selected for battery type. |
| Display shows error code or abnormal readings. | Internal fault; battery fault. | Disconnect charger, wait a few minutes, then reconnect. If error persists, the battery may be faulty or the charger requires service. |
| Pulse repair mode not working for LiFePO4. | Pulse repair is not compatible with LiFePO4 batteries. | This is normal operation. The repair function is only for lead-acid batteries. |
