Troubleshooting
If you encounter issues with your charger, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger not turning on / No LED indication | No AC power; Faulty AC cable; Charger malfunction. | Check AC power outlet and cable connection. Try a different outlet. Ensure the charger is connected to the battery. |
| Charger not charging (Green light ON, but battery not full) | Battery not connected properly; Battery voltage too low (below 0V); Battery fault. | Ensure DC cables are securely connected to the battery with correct polarity. The 0V smart charge function should attempt to reactivate deeply discharged batteries. If the issue persists, the battery may be faulty. |
| Red light flashing, but charging seems slow or stops prematurely | Battery capacity is very high; Charger overheating; Internal protection activated. | Ensure adequate ventilation around the charger. Check for any obstructions to the cooling fan. If the charger is hot, disconnect it and allow it to cool. Verify battery health. |
| Charger LED indicates an error (e.g., rapid flashing, specific color not listed) | Reverse polarity; Short circuit; Overvoltage/Overcurrent; Battery fault. | Immediately disconnect the charger from both AC and DC. Check all connections for correct polarity and ensure no short circuits. Inspect the battery for damage. Reconnect carefully. If the error persists, contact support. |
If troubleshooting steps do not resolve the issue, please contact Enjoybot customer support.
