7.2. Understanding the LCD Display

The large digital display provides real-time information about the charging process:

Hiyiton C45A LCD Display.

• Battery Voltage Indicator: Shows the current voltage of the battery during charging.
• Winter Mode Indicator (Snowflake): Lights up if the external temperature is below 10°C, adjusting charging for cold weather.
• Summer Mode Indicator (Sun): Lights up if the external temperature is higher than 28°C, adjusting charging for hot weather.
• Current Charging Mode Indicators (LOW, MEDIUM, HIGH): Shows the selected charging current level.
• Repair Mode Indicator (Wrench): Lights up when Repair Mode is active.
• Charging Saturation State: Displays the approximate charge level of the battery (20%, 50%, 80%, 100%).
• Mode Selection Button: Used to cycle through charging current modes and activate Repair Mode.

7.3. Selecting Charging Mode

1. The charger will automatically detect the battery voltage (6V, 12V, or 24V).
2. Press the Mode Selection Button (labeled '9' on the display diagram) to cycle through the available charging current modes: LOW, MEDIUM, HIGH. Select the appropriate mode based on your battery's capacity and desired charging speed. Refer to the 'Selectable Charging Current Modes' table in the Specifications section for current values.
3. To activate Repair Mode (labeled '7' on the display diagram), press the mode button until the 'REPAIR' indicator lights up. This mode is used to improve battery health or activate dormant batteries.

7.4. Monitoring the Charging Process

The charger will automatically proceed through its 9-stage smart charging process. Monitor the LCD display for real-time information. The charger will automatically stop charging once the battery reaches full saturation (100%).

7.5. Disconnecting the Charger

1. Once charging is complete and the charger has automatically stopped, unplug the charger from the AC power outlet.
2. Disconnect the black (-) clamp from the battery's negative (-) terminal.
3. Disconnect the red (+) clamp from the battery's positive (+) terminal.

8. Maintenance

• Keep the charger clean and dry. Use a soft, dry cloth to wipe down the exterior.
• Store the charger in a cool, dry place away from direct sunlight and moisture when not in use.
• Regularly inspect the battery clamps and cables for any signs of damage, fraying, or corrosion. Replace if necessary.
• Ensure battery terminals are clean and free of corrosion for optimal connection and charging efficiency.

9. Troubleshooting

• Charger not turning on:
  • Check if the AC power cable is securely plugged into both the charger and the wall outlet.
  • Verify that the wall outlet is functional by plugging in another device.
• Charger not charging the battery:
  • Ensure the battery clamps are correctly connected: red (+) to positive (+), black (-) to negative (-). The charger has reverse connection protection, which will prevent charging if connected incorrectly.
  • The battery might be severely discharged or damaged. Try using the 'Repair Mode' if applicable.
  • Check if the battery voltage is within the charger's supported range (6V, 12V, 24V).
• Error message on display:
  • If an unfamiliar error code or message appears, disconnect the charger, wait a few minutes, and reconnect. If the issue persists, contact customer support.
• Battery not holding charge after charging:
  • The battery may be old, sulfated, or internally damaged and might need replacement. The charger's 'Repair Mode' can help with some battery issues, but not all.

10. User Tips

• Voltage Maintenance: The Hiyiton C45A charger is designed with intelligent control and a 9-stage charging process, including float and maintenance charging. This functionality helps to actively maintain battery voltage and can detect potential voltage dips or spikes during the charging cycle, optimizing battery health over time.
• Not a Jump Starter: It is important to understand that this device is a battery charger and maintainer, not a jump starter. Its primary function is to charge a weak battery over time, allowing the vehicle to start once the battery is sufficiently charged. It is not designed to provide immediate high current to start a vehicle with a completely dead battery.
• Portable Convenience: Take advantage of the portable design with integrated cable management. Wrap the power cords and clip the clamps to the sides for neat storage and easy transport.
• Optimal Charging in Extreme Weather: Trust the automatic Winter and Summer modes to adjust charging parameters based on ambient temperature, ensuring your battery receives the correct charge regardless of the season.

The charger's repair mode can help restore battery performance.
