Vacuum charges extremely slowly or never reaches full charge, but no error code is shown

Safety first: Use only the Panasonic charger specified for your model.

• 1. Time the charge: Note how long it takes to go from low to full according to the indicator. Compare with the manual's specified charge time.
• 2. Check charger temperature: The charger should be warm but not hot. Excessive heat may indicate a failing charger.
• 3. Clean contacts: Wipe the charger and battery contacts with a dry cloth.
• 4. Test with another charger or battery (if available): Swap components to determine whether the charger or battery is at fault.
• 5. Replace failing component: Replace the charger or battery pack with genuine Panasonic parts as indicated by your tests.
