Please ensure the plug is fully inserted. *Note: Some scooter models may have unique port wiring.* **Charger Light Turns Off When Connected:** This typically triggers the charger's internal short-circuit protection. We recommend having your scooter's battery and wiring inspected by a professional. **Battery Not Holding Charge:** Lithium batteries have a finite lifespan. If your battery is over 12 months old or has been stored unused for extended periods, it may have reached the end of its service life and require replacement. 【Safety & Usage Instructions】 For your safety, always inspect the charger and battery for any damage before use. Do not use if either appears damaged. Always unplug the charger from the wall outlet once charging is complete (indicated by a solid Green light).
