4. Charging
To ensure optimal performance and longevity of your VB-08 battery, follow these charging guidelines:
- Always use the original CATCHWELL CX Pro Vacuum Cleaner charger and charging dock. Using unauthorized chargers may damage the battery and void your warranty.
- For first-time use, fully charge the battery before operating the vacuum cleaner.
- Connect the CX Pro Vacuum Cleaner (with the VB-08 battery installed) to its charging dock or directly to the charger.
- Monitor the charging indicator lights on your CX Pro Vacuum Cleaner. These lights will typically show the charging status and indicate when the battery is fully charged.
- Avoid overcharging the battery. Once fully charged, disconnect the vacuum from the charger if not in use for extended periods.

5. Maintenance and Storage
Proper care and storage will extend the life of your VB-08 battery:
- Keep the battery contacts clean and free from dust or debris. Use a dry cloth to wipe them if necessary.
- Store the battery in a cool, dry place, away from direct sunlight and extreme temperatures.
- If the battery will not be used for an extended period (e.g., several months), store it with approximately a 50% charge. Recharge it every 3-6 months to prevent deep discharge, which can reduce battery life.
- Do not store the battery fully discharged or fully charged for long periods.
6. Troubleshooting
If you encounter issues with your VB-08 battery, consider the following common solutions:
- Battery Not Charging:
- Ensure the battery is correctly installed in the CX Pro Vacuum Cleaner.
- Verify that the charger and charging dock are properly connected to a working power outlet.
- Check for any visible damage to the charger, cable, or battery contacts.
- Short Run Time:
- Ensure the battery is fully charged before use.
- Battery capacity naturally degrades over time and with usage cycles. If the battery is old, a reduced run time may be normal.
- Operating the vacuum in high-power modes will consume battery faster.
- Vacuum Not Powering On:
- Confirm the battery is fully charged and securely installed.
- Refer to your CX Pro Vacuum Cleaner's manual for general troubleshooting steps related to power issues.
