6. Operation
The Blue Smart IP65 charger utilizes an intelligent 7-stage charging algorithm to optimize battery health and longevity. It also offers Bluetooth connectivity for enhanced control and monitoring.
7-Stage Charging Algorithm
The charger automatically progresses through the following stages to ensure optimal charging for various battery types:
- Test/Charge: Initial assessment and gentle charging for deeply discharged batteries.
- Bulk: Charges the battery at maximum current until it reaches approximately 80% capacity.
- Absorption: Charges at a decreasing current to bring the battery to 100% capacity.
- Float: Maintains the battery at a constant voltage, compensating for self-discharge.
- Storage: Reduces voltage to minimize gassing and corrosion for long-term storage.
- Refresh: Periodically increases voltage to prevent stratification and sulfation.
- Recondition: A special mode to recover deeply discharged or sulfated batteries.

8. Troubleshooting
If you encounter issues with your Blue Smart IP65 charger, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger not starting/no LEDs | No AC power; Incorrect battery connection; Battery voltage too low. | Check AC power supply; Verify correct positive/negative battery connections; If battery is deeply discharged, the charger may take time to initiate. |
| Charger stuck in a specific stage | Battery fault; Incorrect mode selected for battery type. | Check battery health; Ensure the correct charging mode is selected via the mode button or Victron Connect app. |
| Bluetooth connection issues | Out of range; App not updated; Interference. | Move closer to the charger; Update Victron Connect app; Restart phone/tablet and charger. |
| Charger feels warm | Normal operation; Overheating (less common due to high efficiency). | Some warmth is normal during charging. The charger has built-in overheating protection. If it feels excessively hot, ensure adequate ventilation. |
If the problem persists after attempting these solutions, please contact Victron Energy support.
