What are the signs of a car battery running out of power?

The signs before a car battery runs out of power: 1. When the battery indicator shows green, it means the battery is fully charged and in good condition; when the indicator shows black, it means the battery is low and needs charging; when the indicator shows colorless or light yellow, it means the battery is almost depleted. 2. If the charging light suddenly turns on while driving, or the voltmeter in diesel vehicles shows a sudden drop below 24 volts, it indicates a fault in the car's charging system, which stops charging the battery. At this point, the car is continuously draining the battery, which may lead to a dead battery. 3. When turning on the headlights at night with the engine idling, you may notice the lights dimming significantly and the engine shaking noticeably. Increasing the engine speed improves the brightness of the lights, but the condition persists even after driving at high speed for a while. This indicates that the car's charging system is functioning normally, but the battery is either low on power or unable to hold a charge.
