What does the red battery positive and negative indicator on the car dashboard mean?

[StEleanor]

This light is a warning indicator for low battery voltage. If it illuminates or flashes while driving, it may indicate: 1. Insufficient battery charge, requiring extended driving to recharge; 2. Significant degradation in battery capacity, storage function, or charging capability, indicating the battery is nearing end of life; 3. Loose connections at the battery's positive and negative terminals, causing abnormal power usage; 4. If none of the above issues are present, contact a 4S shop to determine the cause of the light illuminating while driving. When using the vehicle, pay attention to the following points: ① Regularly clean dirt and dust from the generator's surface to maintain cleanliness and good ventilation. ② Frequently check the tightness of all fasteners related to the generator and promptly tighten any loose screws. ③ Ensure the drive belt tension is appropriate. If too loose, it may slip and cause insufficient power generation; if too tight, it may damage the belt and generator bearings.
