3. Safety Information
Read and understand all safety instructions before using the Weego BCM1. Failure to follow these instructions may result in electric shock, fire, or serious injury.
- Battery Acid: Batteries contain sulfuric acid. Avoid contact with skin, eyes, or clothing. In case of contact, flush with water immediately.
- Explosive Gases: Batteries generate explosive hydrogen gas during normal operation. Ensure adequate ventilation and avoid open flames or sparks near the battery.
- Proper Connection: Always connect the positive (+) charger lead to the positive (+) battery terminal and the negative (-) charger lead to the negative (-) battery terminal. Ensure a secure connection.
- Indoor Use: This charger is intended for household use and should be used in a well-ventilated area.
- Damage: Do not operate the charger if it has been damaged in any way. Contact customer support for assistance.
4. Setup
Follow these steps to properly set up your Weego BCM1 Battery Charger and Maintainer:
- Choose Connection Method: Decide whether to use the mini clamp wire set for temporary connections or the terminal wire set for semi-permanent installation.
- Connect to Battery:
- For mini clamps: Attach the red (+) clamp to the positive (+) battery terminal and the black (-) clamp to the negative (-) battery terminal.
- For terminal wire set: Securely attach the red (+) ring terminal to the positive (+) battery post and the black (-) ring terminal to the negative (-) battery post. Ensure the fuse holder is easily accessible.
- Connect Charger to Wire Set: Plug the charger's output cable into the chosen wire set (mini clamps or terminal rings) using the SAE connectors.
- Plug into AC Outlet: Plug the charger's AC power cord into a standard 110-120V AC wall outlet.

5. Operating Instructions
The Weego BCM1 is designed for automatic operation. Once connected, it will automatically detect the battery voltage (6V or 12V) and begin the charging process.
- Automatic Voltage Detection: The charger will automatically identify if the connected battery is 6V or 12V.
- Charging Cycle: The charger employs a multi-stage charging process to optimize battery health and charge efficiency.
- Overcharge Protection (Float Mode): Once the battery reaches full charge, the BCM1 automatically switches to a maintenance (float) mode. This prevents overcharging and keeps the battery at an optimal level without damage.
- Reconditioning Desulfator: The charger includes a reconditioning desulfator feature that uses high-frequency pulse current technology to dissolve unwanted sulfates, helping to restore and maintain battery health.

6. Modes and Indicators
The Weego BCM1 features a clear LED indicator to communicate the charging status:
- Slow Flashing Green Light: Indicates that the battery is currently charging.
- Solid Green Light: Indicates that the battery is fully charged and the charger has entered maintenance (float) mode.
- Fault Indicator: If a fault is detected (e.g., incorrect connection, damaged battery), the indicator may display a specific pattern or color. Refer to the owner's manual for detailed fault code explanations.

7. Maintenance
To ensure the longevity and optimal performance of your Weego BCM1, follow these maintenance guidelines:
- Cleaning: Disconnect the charger from the AC outlet and the battery before cleaning. Use a dry, soft cloth to wipe the exterior. Do not use harsh chemicals or abrasive materials.
- Storage: Store the charger in a cool, dry place when not in use. Ensure cables are neatly coiled to prevent damage.
- IP65 Rating: The BCM1 is IP65-rated, meaning it is resistant to water, dust, and dirt. This makes it suitable for use in garages, sheds, and outdoor environments. However, it is not designed for submersion.
- Cable Inspection: Regularly inspect the charger cables and connectors for any signs of damage, fraying, or corrosion. Replace damaged components immediately.

8. Troubleshooting
If you encounter issues with your Weego BCM1, refer to the following common troubleshooting steps. For more detailed information, consult the full owner's manual.
- Charger Not Turning On: Ensure the AC power cord is securely plugged into a live outlet. Check for tripped circuit breakers.
- No Charging Indication: Verify that the battery connections (clamps or terminals) are clean and secure. Ensure the charger's output cable is firmly connected to the battery wire set.
- Fault Light On: A fault light indicates an issue. This could be due to a short circuit, reverse polarity connection, or a severely damaged battery. Disconnect the charger, check all connections, and inspect the battery for visible damage.
- Battery Not Holding Charge: If the charger indicates a full charge but the battery quickly loses power, the battery itself may be old or damaged and require replacement.
