5. Maintenance and Care
Proper care extends the lifespan of your Avalsor Replacement Battery:
- Charging Habits: Always use the original Cyber G9 charging adapter. Avoid overcharging by disconnecting the vacuum once fully charged, though modern batteries often have protection circuits.
- Storage: If the vacuum cleaner will not be used for an extended period (e.g., several weeks or months), store the battery with approximately 50% charge. Store in a cool, dry place, away from direct sunlight and extreme temperatures.
- Cleaning Contacts: Periodically inspect the metal contacts on both the battery and the vacuum cleaner for any dust or debris. Clean them gently with a dry, soft cloth if necessary to ensure good electrical connection.
- Disposal: When the battery reaches the end of its useful life, dispose of it responsibly at an authorized recycling facility. Do not dispose of batteries in household waste or incinerate them.
6. Troubleshooting
If you encounter issues with your Avalsor Replacement Battery, consider the following:
- Battery Not Charging:
- Ensure the charging adapter is securely connected to both the vacuum and a functional power outlet.
- Check the charging cable and adapter for any visible damage.
- Verify that the Avalsor Replacement Battery is correctly seated in the vacuum cleaner's compartment.
- Reduced Run Time:
- This may indicate that the battery is nearing the end of its expected lifespan.
- Ensure the vacuum cleaner's filters are clean. Clogged filters can increase motor strain and lead to faster battery depletion.
- Confirm the battery has been fully charged before use.
- Vacuum Not Powering On:
- Confirm the battery is fully charged and correctly installed.
- If the issue persists after checking the battery, consult your Cyber G9 vacuum cleaner's main instruction manual for further troubleshooting steps related to the vacuum unit itself.
If these steps do not resolve the issue, please contact Avalsor customer support.
