Vacuum runs for only a few minutes on a full charge, then stops without an error code

Safety first: Do not open the battery pack casing.

• 1. Fully charge the battery: Charge until the charger indicates full. Leave it on the charger for an additional 30 minutes to ensure cell balancing.
• 2. Test run time: Use the vacuum continuously on standard mode and time how long it runs. Compare with the runtime specified in the user manual.
• 3. Repeat for confirmation: Perform a second full charge and discharge cycle. If runtime remains significantly below specification, the battery capacity has degraded.
• 4. Replace the battery pack: Purchase a genuine Panasonic replacement battery pack compatible with your model. Install according to the manual.
• 5. Battery care tips: Avoid storing the vacuum fully discharged and do not leave it in hot environments (e.g., cars, near heaters).
