1.  Inspect the battery shape. If swelling, deformation, or other abnormalities are detected, immediately discontinue use.

2.  Check the battery seal. If leakage, cracks, or damage are observed, contact customer service directly for handling.

3.  Verify the external label on the battery to ensure the voltage and model of the new battery match the original.

 

Step 2: During Replacement – Precautions for Power Cable Contacts and Orientation

1.  Inspect and clean the power cable contacts. Use a dry cloth to wipe the metal contacts, removing any oxidation layer on the surface.

2.  After unstall  the old battery, press power botton for about 10 seconds. And then align the plug and socket correctly during insertion, ensuring the fool-proof tab is oriented properly to prevent short circuits.

3.  Insert the plug into the socket slowly to avoid damage caused by forceful insertion or removal.

1.  After replacement, charge the scooter in an open, well-ventilated area away from flammable materials for the initial charging session.

2.  Perform an initial pre-charge of 10 minutes after battery replacement. Monitor the indicator lights and controller status during charging. If any abnormalities are detected, immediately stop charging and disconnect the battery from the scooter while ensuring personal safety.

3.  Conduct a test run after pre-charging. Ride the scooter at low speed over a short distance on flat ground to confirm stable power output and absence of electrical anomalies.

● When the battery cable contacts the controller, the internal capacitors charge instantaneously, which may produce brief sparks and a “click” sound. These are normal phenomena: The spark is tiny and occurs only once.

● No persistent unusual noises or burnt smells are generated.

● The scooter operates normally afterward.
