Note: The charger is designed with reverse polarity protection. If connected incorrectly, the unit will not operate and an error indicator may display.
Operating Instructions
The BM3B charger operates automatically once connected to a power source and battery:
- Automatic Charging: The charger automatically detects the battery's state and begins charging. It will stop charging automatically when the battery is fully charged.
- Float Mode Monitoring: Once fully charged, the charger switches to float mode, continuously monitoring the battery and providing a small maintenance charge to keep it topped off without overcharging.
- Charging Status Indicators: The unit features LEDs to indicate the charging status (e.g., charging, fully charged, fault).
Charging Time Reference
The charging time can vary based on the battery's Amp-hour (Ah) rating and its current state of discharge. The following chart provides approximate charging times for various battery types:

Troubleshooting
If you encounter issues with your BM3B charger, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger not turning on/no display. | No power from outlet, faulty connection, or damaged unit. | Check power outlet. Ensure secure connection to battery and power. If issues persist, contact support. |
| "Reverse Connection" error or fault indicator. | Battery clamps/terminals connected incorrectly (positive to negative, negative to positive). | Disconnect the charger and reconnect the red clamp to the positive (+) terminal and the black clamp to the negative (-) terminal. |
| Battery not charging or charging slowly. | Battery is deeply discharged, sulfated, or faulty. Incorrect voltage selection. | Ensure correct 6V/12V selection. For deeply discharged batteries, charging may take longer. If battery is severely damaged, it may need replacement. |
| Charger overheats. | Poor ventilation, prolonged use in high temperatures, or internal fault. | Disconnect immediately. Ensure adequate ventilation. If overheating persists, discontinue use and contact support. |
