7. Operating Instructions
The battery powers your cordless vacuum cleaner. For optimal performance:

Before first use, fully charge the battery. This helps to condition the battery for long-term performance.
7.2. Charging the Battery
- Use only the original charger supplied with your vacuum cleaner or a compatible charger specified by the vacuum cleaner manufacturer.
- Connect the charger to a power outlet and then to the vacuum cleaner (with the battery installed) or directly to the battery if your vacuum model supports external charging.
- Monitor the charging indicator lights on your vacuum cleaner or charger. These typically show when the battery is charging and when it is fully charged.
- Avoid overcharging the battery by disconnecting it once fully charged.
7.3. Usage
Operate your vacuum cleaner as per its own instruction manual. The battery provides cordless power, allowing for flexible cleaning without being tethered to a power outlet.
8. Maintenance
Proper maintenance extends the life of your battery:
- Storage: If storing the battery for an extended period, charge it to approximately 50-60% capacity. Store in a cool, dry place away from direct sunlight and extreme temperatures.
- Cleaning: Keep the battery contacts clean and free from dust or debris. Use a dry cloth to wipe them if necessary.
- Temperature: Avoid operating or charging the battery in extreme hot or cold conditions, as this can affect performance and lifespan.
- Regular Use: For best results, use and recharge the battery regularly.
9. Troubleshooting
If you encounter issues with your battery, consider the following:
- Battery not charging:
- Ensure the charger is properly connected to both the power outlet and the vacuum/battery.
- Verify that the power outlet is functional.
- Check for any visible damage to the battery or charger.
- Short runtime:
- The battery may not be fully charged. Ensure it is charged until the indicator shows full.
- Battery capacity naturally degrades over time with repeated charge cycles. If the battery is old, it may need replacement.
- Ensure the vacuum cleaner's filters are clean, as clogged filters can increase motor strain and battery drain.
- Battery not fitting:
- Double-check that your vacuum cleaner model is listed in the compatibility section (Section 5).
- Ensure the battery is aligned correctly with the compartment and inserted firmly.
If problems persist, contact customer support.
