- Power Off: Ensure your robot vacuum cleaner is completely powered off and disconnected from its charging base.
- Access Battery Compartment: Locate and open the battery compartment, typically found on the underside of the vacuum. This may require removing screws or a cover.
- Remove Old Battery: Carefully disconnect the old battery's connector and remove the battery.
- Install New Battery: Connect the new CQCEO battery's connector firmly into the vacuum's port. Ensure the connection is secure.
- Secure Compartment: Place the new battery into the compartment and close the cover, securing any screws.
- Initial Recognition: If the new battery is not recognized immediately after installation, power off the vacuum, then reinstall the battery, ensuring the interface is fully connected.

5. Operating Instructions (Battery Cycling)
For optimal performance and to "wake up" the new battery, it is recommended to perform a full discharge and charge cycle 3-4 times after initial installation:
- First Discharge: Use the vacuum cleaner until the battery level drops to approximately 5%. Do not allow it to discharge completely to 0%.
- Full Charge: Place the vacuum back on its charging base and allow it to charge fully to 100%.
- Repeat Cycle: Repeat steps 1 and 2 for a total of 3-4 cycles. This process helps calibrate the battery's charge indicator and optimize its capacity.
6. Maintenance
Proper maintenance can extend the lifespan of your battery:
- Regular Use: Use your robot vacuum regularly to keep the battery active.
- Avoid Deep Discharge: While the battery has over-discharge protection, consistently running it until it completely shuts down can reduce its overall lifespan. Aim to recharge before it's fully depleted.
- Storage: If storing the vacuum for an extended period, ensure the battery is charged to about 50-70% and store it in a cool, dry place. Recharge every few months to prevent deep discharge.
- Cleaning Contacts: Periodically check and clean the battery contacts and charging pins on the vacuum and charging base to ensure good electrical connection.
7. Troubleshooting
If you encounter issues with your new battery, consider the following:
- Battery Not Recognized:
- Ensure the battery connector is fully and securely plugged into the vacuum's port.
- Try removing and reinstalling the battery to reset the connection.
- Verify that your vacuum cleaner model is listed in the compatibility section.
- Short Operating Time:
- Perform the recommended 3-4 full discharge/charge cycles to optimize battery capacity.
- Ensure the vacuum is charging fully. Check the charging base and contacts.
- Operating conditions (e.g., thick carpets, high power modes) can affect runtime.
- Charging Issues:
- Confirm the charging base is powered and functioning correctly.
- Clean the charging contacts on both the vacuum and the base.
