6. Operating Instructions
6.1. Starting the Charging Process
Once the charger is properly connected to both the battery and the power outlet, it will automatically begin the charging process. The 1.3-inch OLED display will activate, showing real-time charging status.
6.2. 4-Stage Smart Charging
The charger employs a sophisticated 4-stage charging process to optimize battery performance and prevent overcharging:
- Constant Current Mode: Charges the battery quickly by delivering a steady, high current.
- Constant Voltage Mode: Maintains stable charging efficiency by applying a constant voltage as the battery approaches full charge.
- Trickle Mode: Provides a low current to fully top off the battery and maintain its charge without overcharging.
- Power-Off Mode: Automatically stops charging when the battery is fully charged to avoid overcharging and extend battery life.
6.3. Monitoring Charging Status
The integrated 1.3-inch OLED display provides comprehensive real-time information:
- VOL: Displays the current battery voltage.
- CUR: Shows the charging current in Amperes.
- CAP: Indicates the battery capacity charged (OAH - Ampere-hours).
- TIME: Shows the elapsed charging time.
- Abnormal Status: The display will also indicate any abnormal conditions, providing clear visual indicators to monitor the charging process at a glance.
6.4. Completing the Charge
The charger will automatically enter Power-Off Mode once the battery is fully charged. You can then safely disconnect the charger from the power outlet first, and then from the battery.
7. Maintenance
- Cleaning: Keep the charger clean and free from dust and debris. Use a dry, soft cloth for cleaning. Do not use liquid cleaners.
- Storage: Store the charger in a cool, dry place when not in use.
- Cable Inspection: Regularly inspect the input and output cables for any signs of damage, fraying, or loose connections. Replace damaged cables immediately.
- Ventilation: Ensure the charger's ventilation openings are not blocked to allow for proper heat dissipation.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger not turning on / No display | No power from outlet; Loose power connection; Faulty power cable. | Check power outlet with another device; Ensure power cable is securely plugged in; Inspect power cable for damage. |
| Battery not charging | Loose battery connection; Incorrect battery voltage; Deeply discharged battery; Faulty battery. | Ensure battery connections are secure; Verify battery is 24V lead-acid; Allow more time for deeply discharged batteries; Test battery with a different charger or consult a professional. |
| Charger gets excessively hot | Poor ventilation; Overload; Internal fault. | Ensure charger is in a well-ventilated area; Reduce load if possible; Disconnect and contact support if problem persists. |
| OLED display shows "Abnormal Status" | Battery fault; Connection issue; Internal charger fault. | Check battery and connections; Disconnect and reconnect; If error persists, contact support. |
9. User Tips
- Proper Ventilation: Always ensure the charger has ample space for airflow, especially during prolonged charging cycles, to prevent overheating.
- Check Connections: Before each use, quickly verify that all cables are securely connected to both the battery and the power source to ensure efficient charging and prevent sparks.
- Monitor Display: Utilize the clear OLED display to keep an eye on charging progress (voltage, current, capacity) and quickly identify any abnormal conditions.
- Portability: The charger's widened handle makes it easy to carry. Take advantage of its portable design for charging in various locations as needed.
