Why is the battery icon on the car dashboard flashing?

[DiDante]

If the battery icon on the car dashboard is flashing, it could indicate that the car battery is low on power. A depleted battery may cause the dashboard to flicker when starting the engine, and it should be charged promptly. It is recommended to check whether the battery terminals are securely connected or if there are any issues with other wiring in the car. The functions of the car battery include: 1. Providing power to the starting system, ignition system, and electronic fuel injection system when starting the engine; 2. Supplying power to the car's electrical devices when the engine is off or idling at low speed; 3. Assisting in powering electrical devices when the alternator's output is insufficient; 4. Absorbing voltage spikes in the electrical system to protect the car's electronic equipment; 5. Storing excess electricity generated by the alternator.
