2. Setup and Installation
2.1 Safety Precautions
- Do not attempt to disassemble, open, or service the battery pack. This can lead to injury or damage and will void the warranty.
- Replace only with the battery pack designated for this product. Using an incompatible battery may cause damage or fire.
- Do not crush, puncture, short external contacts, or dispose of in fire or water.
- Do not store above 60°C (140°F). High temperatures can degrade battery performance and pose a safety risk.
- Keep the battery away from children and pets.
- If the battery shows signs of damage, swelling, or leakage, discontinue use immediately and dispose of it properly.
2.2 Installation Steps
Follow these steps carefully to replace the battery in your Proscenic NEO 820P or NEO 830P robotic vacuum cleaner:
- Power Off and Unplug: Ensure your robotic vacuum cleaner is completely powered off and unplugged from its charging base or power adapter.
- Access Battery Compartment: Turn the robot vacuum upside down. Locate the battery compartment cover, typically secured by screws. Use a screwdriver to remove the screws and open the cover.
- Disconnect Old Battery: Carefully disconnect the old battery's connector from the robot's port. Gently lift the old battery out of the compartment.
- Insert New Battery: Place the new SUNELL replacement battery into the compartment, ensuring it fits snugly.
- Connect New Battery: Align the new battery's connector with the robot's port and firmly push it in until it clicks into place.
- Secure Cover: Replace the battery compartment cover and secure it with the screws you removed earlier.
- Initial Charge: Place the robot vacuum back on its charging base or connect it to the power adapter for its initial charge.

3. Operation
3.1 First Use and Charging
For optimal performance and battery longevity, it is recommended to fully charge the new battery before its first use. Place your robotic vacuum on its charging dock and allow it to charge until the charging indicator shows a full charge.
3.2 Charging Guidelines
- Always use the original charging dock or power adapter provided with your Proscenic robotic vacuum cleaner.
- Avoid completely draining the battery before recharging. Regular partial charges are generally better for Li-ion battery health.
- Do not leave the battery uncharged for extended periods. If storing the vacuum, ensure the battery has a partial charge (around 50%).
- Charge the battery in a well-ventilated area, away from direct sunlight or heat sources.
4. Maintenance and Storage
4.1 Cleaning
Periodically inspect the battery and its compartment for dust or debris. Use a dry, soft cloth to gently wipe the battery and contacts. Do not use liquid cleaners or solvents.
4.2 Storage
- If the robotic vacuum will not be used for an extended period, remove the battery if possible and store it separately.
- Store the battery in a cool, dry place, ideally at room temperature (20-25°C or 68-77°F).
- Ensure the battery is charged to approximately 50% before long-term storage. Recharge it every 3-6 months to prevent deep discharge.
- Do not store above 60°C (140°F).
5. Troubleshooting
If you encounter issues with your SUNELL replacement battery, refer to the table below for common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Battery not charging | Loose connection; faulty charging dock/adapter; battery deeply discharged. | Ensure battery connector is firmly seated. Test charging dock/adapter with another device if possible. Allow more time for initial charge if deeply discharged. |
| Short run time after full charge | Battery not fully charged; battery degradation (unlikely for new battery); high power consumption by vacuum. | Ensure full charge cycle. Check vacuum for blockages or issues that might increase power draw. |
| Vacuum not powering on | Battery not installed correctly; battery completely drained; vacuum issue. | Re-check battery installation and connection. Charge the battery. If problem persists, consult your vacuum cleaner's manual. |
