Battery indicator LEDs on the handle are inaccurate (e.g., show full but vacuum stops quickly)

Safety first: Remove the battery pack before extended storage or inspection.

• Step 1 – Perform full charge: Charge the battery until the charger indicates full.
• Step 2 – Controlled discharge: Use the vacuum continuously on a medium setting until it stops due to low battery. Do not restart repeatedly.
• Step 3 – Recharge fully: Immediately recharge to full again. This can sometimes recalibrate the indicator.
• Step 4 – Compare runtime: If runtime remains very short despite full indication, the battery is likely worn out.

Replace the battery pack if capacity is low. If a new battery still shows incorrect levels, the handle indicator PCB or main PCB may need service.
