Vacuum makes a clicking or popping sound from the battery area during use.

Safety: Remove the battery.

• Check latch and fit: Ensure the battery locks firmly with no play. Replace a worn latch if necessary.
• Inspect contacts: Look for arcing marks or discoloration on contacts. If present, stop using and replace the battery or connector.
• Monitor behavior: If the sound is minor and the unit does not cut out, it may be harmless expansion. If accompanied by power loss, treat as a contact issue.
