The ABS flame housing ensures durability and safety.
8. Troubleshooting
If you encounter issues with your charger, refer to the following common problems and solutions:
- Charger not turning on: Ensure the power cord is securely plugged into a live outlet and the battery clamps are correctly connected to the battery terminals.
- Display shows an error or protection indicator: The charger has multiple built-in protections (overvoltage, short circuit, reverse connection, overcurrent, overheat, low voltage). Disconnect the charger, check all connections, ensure the battery type is compatible, and allow the unit to cool if overheating is suspected. Reconnect and try again.
- Battery not charging: Verify that the correct charging mode is selected for your battery type. Check the battery's capacity to ensure it is within the 2Ah-150Ah range. If the battery is severely damaged or sulfated, try the Pulse Repair mode.
- LiFePO4 battery warning: If charging a LiFePO4 battery, ensure it has a functional Battery Management System (BMS). Charging without a BMS is prohibited and dangerous.
If the problem persists after following these steps, contact customer support.
