4. Operation Instructions
4.1 Preparation Before Use
- Check the battery: Confirm that the battery is a lead-acid battery (Calcium, GEL, AGM, Wet, EFB, etc.) with voltage 12V and capacity between 4-100Ah. Ensure the battery is not leaking, swollen, or damaged.
- Check the charger: Inspect the charger's power cord, plug, and interface for damage. Ensure the fan is working normally (no blockage).
- Choose a suitable location: Place the charger in a dry, well-ventilated area, away from high temperatures, open flames, direct sunlight, and water sources. Keep it away from children and pets.
4.2 Charging/Repair Steps
- Connect the charger to the battery: Correctly connect the charger's positive (red) clip to the battery's positive terminal (+), and the negative (black) clip to the battery's negative terminal (-). Ensure the connection is firm to avoid poor contact.
Image: Step 1 shows connecting the red clamp to the positive battery terminal and the black clamp to the negative terminal.
- Plug in the power cord: Insert the charger's power plug into an AC 110-220V, 50-60Hz power outlet. The charger will start self-checking, and the LCD display will light up.
Image: Step 2 illustrates plugging the charger into a power outlet.
- Choose the right mode: According to your battery type (AGM, GEL, Wet, etc.) and needs (charging or pulse repair), press the 'MODE' button to select the corresponding mode. The LCD display will show the selected mode and battery voltage.

- Completion of work: When the battery is fully charged or the pulse repair is completed, the charger will automatically switch to trickle charge mode (to maintain battery power) or stop working. The LCD display will show "FUL" or corresponding prompt. Keep the charged status for 1-2 hours is highly recommended.
- Disconnect the charger: First, unplug the power cord from the power outlet, then disconnect the clips from the battery terminals (remove the negative clip first, then the positive clip) to avoid electric sparks.

5. Maintenance and Care
- Keep the charger clean: After use, wipe the charger's surface and clips with a dry, soft cloth to remove dust, dirt, and battery electrolyte (if any) to prevent corrosion.
- Regular inspection: Periodically check the power cord, plug, and clips for damage, aging, or loose connections. If any problem is found, stop using it immediately and replace with original accessories.
- Storage: When not in use for a long time, store the charger in a dry, cool, and well-ventilated place, away from dust and humidity. Do not store it together with flammable, explosive, or corrosive items.
- Fan maintenance: Ensure the charger's fan is not blocked by dust or other objects. If the fan is blocked, clean it with a soft brush to ensure normal cooling.
6. Troubleshooting
| Problem | Possible Causes | Solution |
|---|---|---|
| LCD display does not light up | 1. Power cord is not plugged in properly; 2. Power outlet is faulty; 3. Power cord or plug is damaged. | 1. Replug the power cord; 2. Replace the power outlet; 3. Replace the power cord/plug with original ones. |
| Charging does not start | 1. Battery connection is loose/incorrect; 2. Battery voltage is lower than 8.0V; 3. Wrong mode selected. | 1. Reconnect the battery clips correctly; 2. Replace the battery or use a booster charger first; 3. Select the correct mode. |
| Charger overheats | 1. Poor ventilation; 2. Fan is blocked; 3. Ambient temperature is too high. | 1. Move to a well-ventilated place; 2. Clean the fan; 3. Reduce ambient temperature. |
| Pulse repair fails | 1. Battery is severely damaged/swollen; 2. Wrong battery type; 3. Battery voltage is too low. | 1. Replace the battery; 2. Select the correct battery type; 3. Boost the battery first. |
| LCD displays "FUL" but battery is not fully charged | Battery internal resistance is too large, or capacity is reduced (e.g., feeder battery, vulcanized battery, low voltage/long-idle time battery). Voltage soars, causing premature "FUL" status. | Press the "repair" button to activate the battery. |
| Unable to reach "FUL" status after long charging time | Battery is vulcanized, feeder, or has water depletion. Battery voltage remains low. | Stop charging if the battery is heating. Check for liquid shortage. Perform 1-2 discharge-charge cycles. |
7. User Tips
- Always ensure the charger's input voltage matches your power source (AC 110-220V).
- For optimal battery health, consider using the pulse repair function periodically for older or underperforming batteries.
- The temperature displayed on the LCD is for reference only; always ensure the charger is in a well-ventilated area.
- If the charger displays "El-I-" or an anomaly, double-check your battery connections for correct polarity.
- After charging, it is recommended to keep the battery in a charged state for 1-2 hours before disconnecting for optimal performance.
