6. Operating Instructions
The YUANRI charger features a 7-stage smart charging process and intuitive LED indicators for easy monitoring.
6.1. Charging Process
The charger automatically detects the battery's state and applies the appropriate charging stage:
- Stage 1-6 (Bulk to Absorption): The charger delivers a high current (up to 25A) and then gradually reduces it as the battery voltage rises.
- Stage 7 (Float/Trickle): Once the battery is fully charged, the charger automatically switches to a low-current trickle mode to maintain the charge without overcharging.
6.2. LED Indicator Status
Monitor the 3-color LED indicator on the charger for real-time status:
- Red Flash: Low Charging (Battery charge less than 80%)
- Yellow Flash: Normal Charging (Battery charge between 80% and 99%)
- Green Flash: Trickle Mode (Battery is nearly full, maintaining charge)
- Green On: Fully Charged (Battery is 100% charged)
- Red/Green Flash: No-Load (Charger is powered on but not connected to a battery or battery is faulty)

7. Maintenance
- Cleaning: Regularly wipe the charger's exterior with a dry, soft cloth. Do not use harsh chemicals or abrasive cleaners.
- Ventilation: Ensure the cooling fan and vents are free from dust and debris to maintain optimal heat dissipation.
- Cable Inspection: Periodically check the AC and DC cables for any signs of damage, fraying, or exposed wires. Replace damaged cables immediately.
- Storage: When not in use, store the charger in a cool, dry place, away from direct sunlight and extreme temperatures.
- Connector Care: Keep the Anderson connector clean and free of corrosion to ensure a reliable connection.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger not turning on (no LED activity) | No power from AC outlet; faulty AC cable; internal fault. | Check AC outlet with another device. Inspect AC cable for damage. Contact support if problem persists. |
| Red/Green LED flashes (No-Load) | Battery not connected; poor connection; battery voltage too low or too high; incompatible battery type. | Ensure DC connector is firmly attached. Verify battery is 24V lead-acid. Check battery voltage. |
| Charger gets excessively hot | Poor ventilation; blocked cooling fan; prolonged high-current charging in hot environment. | Ensure adequate ventilation. Clear any obstructions from the fan. Allow charger to cool down. If overheating persists, contact support. |
| Battery not charging or charging slowly | Poor connection; battery fault; charger fault. | Check all connections. Test battery with a multimeter. Contact support if battery is confirmed good and charger is not performing. |
