[Pierce]

The reasons for the constant red light on the Wuling Hongguang mini during charging are: 1. There is a fault in the vehicle's charging system or power supply system; 2. The generator belt or tensioner is too loose, causing the power supply system to malfunction and the battery light to illuminate; 3. Severe oxidation or looseness of the battery terminals leads to poor contact and the battery light to illuminate. The maintenance methods for the vehicle battery are: 1. Charge the battery promptly when the ammeter shows insufficient power; 2. Adjust the density of the electrolyte according to different regions and seasons based on standards; 3. Add distilled water or special replenishing fluid when the electrolyte is low; 4. The total duration of starting the vehicle each time should not exceed 5 seconds; 5. Start the car periodically when the battery is not in use for a long time; 6. Regularly check if the small holes on the battery cover are ventilated; 7. Check for oxidation on the positive and negative terminals of the battery; 8. Inspect all parts of the circuit for aging or short circuits.
