Safety Precautions

To ensure safe operation and prevent damage, please observe the following precautions:

• Before use, inspect the charger for any damage or loose internal parts. Do not use if damaged.
• This charger is designed exclusively for lead-acid batteries (12V/24V, 3Ah-200Ah). Do not attempt to charge lithium batteries.
• Avoid over-discharging lead-acid batteries or leaving them unused for extended periods, as this can cause significant damage and prevent charging.
• Operate the charger in a well-ventilated area. Avoid humid, high-temperature, or flammable/explosive gas environments.
• Ensure cooling holes are not blocked during charging. If the cooling fan does not operate after power-on, disconnect power immediately and do not use the charger.
• Do not leave the charger unattended during operation.
• Do not use the battery while it is being charged by this unit.

Product Features

• Pulse Repair Charger: Equipped with an intelligent microcomputer chip and broadband pulse technology for automatic 5-stage charging and battery repair.
• Automatic Voltage Identification: Automatically detects and adapts to 12V (8-14.5V) or 24V (18-29V) lead-acid batteries.
• Two Charging Modes: "MOTOR" mode for 3AH to 20AH batteries and "AUTO" mode for 20AH to 200AH batteries, selectable via a button.
• Automatic Stop at Full Power: Input current automatically drops to 0A when the battery is fully charged, preventing overcharging.
• Intuitive Interface: LED display shows power percentage, charging status, and progress.
• Multi-Protection System: Includes overheat, short circuit, reverse polarity, over-current, and over-voltage protection.
• Efficient Cooling: Built-in cooling fan and good cooling structure for effective heat dissipation.

Setup

Follow these steps to set up your Etrogo battery charger:

1. Connect Battery Clamps:
   • Connect the red (+) clamp to the positive terminal of the battery.
   • Connect the black (-) clamp to the negative terminal of the battery.

   Ensure a secure connection. Incorrect polarity connection will trigger reverse polarity protection.
2. Plug into Power Outlet: Insert the charger's AC power plug into a standard AC 110V-250V, 50-60Hz electrical outlet.
3. Automatic Voltage Detection: The charger will automatically detect whether it is connected to a 12V or 24V battery. The corresponding indicator light (12V or 24V) on the display will illuminate.

Operating Instructions

Once connected, the charger will begin its operation sequence:

1. Voltage Recognition: The charger automatically identifies the battery voltage (12V or 24V) upon connection. The corresponding LED will light up.

2. Select Charging Mode: Use the "Charging Mode" switch (AUTO/MOTOR) on the charger's front panel to select the appropriate mode:
   • MOTOR Mode: Suitable for smaller batteries, typically 3AH to 20AH. This is often the smart/default mode.
   • AUTO Mode: Recommended for larger batteries, typically 20AH to 200AH, or when the MOTOR mode cannot initiate charging.

5. Disconnecting: Once charging is complete, first unplug the charger from the AC power outlet, then disconnect the black (-) clamp, followed by the red (+) clamp from the battery terminals.

Maintenance

Proper maintenance ensures the longevity and optimal performance of your charger:

• Cleaning: Keep the charger clean and free from dust and debris. Use a dry, soft cloth for cleaning. Do not use liquids or abrasive cleaners.
• Storage: Store the charger in a cool, dry, and well-ventilated place when not in use. Avoid extreme temperatures and direct sunlight.
• Cable Inspection: Regularly inspect the power cord and battery clamps for any signs of damage, fraying, or corrosion. Replace if necessary.
• Ventilation: Always ensure the charger's cooling vents are unobstructed during operation to prevent overheating.

Troubleshooting

If you encounter issues with your charger, refer to the following common troubleshooting steps:

• Charger Not Turning On:
  • Check if the AC power cord is securely plugged into a live outlet.
  • Ensure the battery clamps are correctly and securely connected to the battery terminals.
  • Verify that the battery voltage is within the charger's operating range (12V or 24V).
• Charging Indicator Not Lighting Up:
  • Confirm the battery is not already fully charged. The indicator turns off when full.
  • Check for proper connection of battery clamps.
  • Ensure the battery is a compatible lead-acid type and not a lithium battery.
• Charger Overheating:
  • Ensure the charger is in a well-ventilated area.
  • Check that the cooling fan is operating and vents are not blocked.
  • If overheating persists, disconnect immediately and contact support.
• Error Displayed:
  • Refer to the display for specific error codes or messages.
  • Common errors might relate to reverse polarity (recheck clamp connections), short circuit (inspect cables), or over-voltage/low-voltage (check battery condition).
