What Does the Battery Symbol on the Car Dashboard Mean?

[Vivienne]

When the battery symbol appears on the car dashboard, it indicates a fault in the battery system. The solutions are: 1. Check if the battery terminals are oxidized. If oxidation is present, clean and polish them before reinstalling and testing the vehicle, as oxidation can sometimes hinder battery charging; 2. Inspect the battery terminals for any signs of looseness. The functions of the battery are: 1. To supply power to the starting system, ignition system, and electronic fuel injection system when starting the engine; 2. To power the vehicle's electrical equipment when the engine is off or idling at low speed; 3. To provide power to electrical devices when the generator output is insufficient; 4. To mitigate voltage surges in the electrical system and protect the vehicle's electronic equipment; 5. To store excess electricity generated by the alternator.
