5. Operating Instructions
The charger offers four distinct charging modes to suit various battery types and conditions.
Mode Selection:
After connecting the battery and power, use the mode selection buttons on the charger to choose the appropriate mode:
- LITHIUM Mode: For charging 12.6V / 25.2V Lithium-ion batteries.
- ORDINARY Mode: For charging 12V/24V SLA batteries including Wet, MF, Gel, Flooded, deep cycle, and VRLA maintenance-free lead-acid batteries.
- AGM Mode: For charging 14.8V / 29.6V AGM/EFB batteries.
- MAINTENANCE Mode (Pulse Repair): Used to recover and repair deeply discharged or sulfated batteries. This process typically takes about 1 hour before transitioning to automatic charging.
Figure 5.1: Four Modes Selection. This image shows the four distinct buttons for selecting Lithium, Ordinary, AGM, and Maintenance modes, along with a brief explanation of how to use the Maintenance (Repair) mode.
Figure 5.2: Three Battery Types State of Charge. This image illustrates how the charger displays the state of charge for Lead-Acid/GEL/Flooded (Ordinary), 12.6V Lithium, and AGM/EFB batteries on its LCD screen.
Figure 5.3: Battery Compatibility. This image shows the charger's compatibility with various battery types, including Lithium, Gel, AGM, and Lead-Acid batteries, emphasizing its ability to charge and repair 12V or 24V SLA batteries and 12.6V Lithium batteries.
Once the mode is selected, the charger will automatically begin the charging process. It employs a 7-step charging sequence to detect, charge, desulfate, and maintain your vehicle battery automatically. The charger will automatically adjust the charge current based on ambient temperature.
When the battery is fully charged, the charger will automatically switch to float charge mode, extending battery service life. The LCD display will indicate full charge (current drops below 0.5A and the indicator stops flashing).
6. Maintenance
Proper maintenance ensures the longevity and optimal performance of your battery charger and batteries.
- Cleaning: Disconnect the charger from power and battery. Wipe the casing with a soft, dry cloth. Do not use harsh chemicals or abrasives.
- Storage: Store the charger in a cool, dry place when not in use. Ensure cables are neatly coiled and not kinked.
- Battery Maintenance: Regularly check battery terminals for corrosion and clean as necessary. Ensure battery fluid levels are adequate for non-sealed batteries.
- Pulse Repair (Maintenance Mode): Utilize the MAINTENANCE mode periodically to help desulfate and recover older or underperforming batteries, which can extend their lifespan.
7. Troubleshooting
If you encounter issues with your charger, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger not turning on / LCD blank | No AC power; loose connection; faulty outlet. | Check power cord connection; try a different outlet; ensure power is supplied to the outlet. |
| Charger not charging battery | Incorrect mode selected; poor clamp connection; battery too deeply discharged or damaged; reverse polarity. | Select correct mode for battery type; ensure clamps are securely connected to correct terminals; try MAINTENANCE mode for deeply discharged batteries; check for reverse polarity (charger has protection). |
| "Error" message on LCD | Internal fault; battery fault; short circuit. | Disconnect charger, wait a few minutes, then reconnect. If error persists, the battery may be faulty or contact customer support. |
| Charger gets hot during operation | Normal operation (especially during high current charging); poor ventilation. | Ensure adequate ventilation around the charger. The built-in fan should manage heat. If excessively hot, disconnect and contact support. |
The charger's pulse repair function can help diagnose and rescue batteries that have lost capacity due to sulfation. If a battery does not respond to charging or repair, it may need replacement.
