5. Operating Instructions
5.1. Charging the Battery
- Initial Charge: For optimal performance, fully charge the battery before its first use. This may take several hours.
- Regular Charging: Connect your vacuum cleaner (with the Fieety Ultra 8 battery installed) to its original charger. The charging indicator on your vacuum cleaner will typically show the charging status.
- Avoid overcharging: Modern Lithium-ion batteries are designed to prevent overcharging, but it is generally good practice to disconnect the charger once the battery is fully charged.
5.2. Using the Vacuum Cleaner
Once the battery is fully charged, you can operate your vacuum cleaner as usual. The Fieety Ultra 8 battery is designed to provide reliable power for your cleaning tasks. Expected run time will vary based on the vacuum cleaner model and power settings used.
6. Maintenance
- Cleaning: Wipe the battery and its contacts with a clean, dry cloth if necessary. Do not use liquid cleaners or solvents.
- Storage: If storing the battery for an extended period, ensure it is partially charged (around 50%) and stored in a cool, dry place away from direct sunlight and extreme temperatures.
- Avoid deep discharge: While Lithium-ion batteries do not suffer from memory effect, avoiding complete discharge before recharging can help prolong battery life.
7. Troubleshooting
- Battery not charging:
- Ensure the charger is properly connected to both the vacuum cleaner and a working power outlet.
- Verify that the battery is correctly installed in the vacuum cleaner.
- Check if the charger or vacuum cleaner has any visible damage.
- Short run time:
- New batteries may require a few charge/discharge cycles to reach full capacity.
- Ensure the battery is fully charged before use.
- High power settings on the vacuum cleaner will consume battery power faster.
- Battery not fitting:
- Double-check the compatibility of the Fieety Ultra 8 battery with your specific vacuum cleaner model.
