5. Installation Guide
Replacing your robot vacuum's battery is a straightforward process, typically taking around 2 minutes. Always ensure the robot vacuum is powered off and unplugged from its charging base before beginning.

This image provides a detailed view of the battery's connector, emphasizing the importance of matching it with the original battery's connector type for proper installation. The wiring includes red, black, and white leads.
- Power Off: Turn off your robot vacuum cleaner and disconnect it from its charging station.
- Access Battery Compartment: Flip the robot vacuum over. Locate the battery compartment cover, usually secured by screws. Use a screwdriver to remove the screws and open the cover.
- Remove Old Battery: Carefully disconnect the old battery's connector from the robot vacuum's port. Lift out the old battery.
- Install New Battery: Insert the new RDSJ 6800mAh battery into the compartment. Ensure the battery is oriented correctly.
- Connect Battery: Align the new battery's connector with the robot vacuum's port and firmly plug it in. Ensure a secure connection. Confirm the connector is the same type as your original battery.
- Close Compartment: Replace the battery compartment cover and secure it with the screws.
- Initial Charge: Place the robot vacuum back on its charging station and allow it to fully charge before its first use.
6. Operating Instructions
After successful installation, operate your robot vacuum cleaner as per its original manufacturer's instructions. The new battery is designed to provide extended runtime.
- First Use: For optimal performance, fully charge the battery before its initial use.
- Regular Charging: Always return the robot vacuum to its charging base after each cleaning cycle to ensure the battery remains charged and ready for the next use.
- Storage: If storing the robot vacuum for an extended period, ensure the battery is charged to approximately 50-60% and store it in a cool, dry place. Recharge every 3-6 months to prevent deep discharge.
7. Maintenance Tips
Proper maintenance can help extend the lifespan of your replacement battery:
- Avoid Extreme Temperatures: Do not expose the battery or robot vacuum to extreme heat or cold, as this can degrade battery performance and lifespan.
- Regular Cleaning: Keep the robot vacuum's charging contacts clean to ensure efficient charging.
- Deep Discharge Avoidance: Avoid completely draining the battery frequently. Modern Li-ion batteries perform best when kept within a charge range and not allowed to drop to 0% often.
8. Troubleshooting
If you encounter issues with your new battery, consider the following:
- Battery Not Charging:
- Ensure the battery connector is securely plugged in.
- Verify the robot vacuum is properly seated on its charging base and the base is powered.
