Can You Charge the Battery When the Car Doesn't Start?

[VanGenesis]

You can charge the battery when the car doesn't start. The functions of a car battery are: 1. To supply power to the starting system, ignition system, and electronic fuel injection system during engine startup; 2. To provide power to the car's electrical equipment when the engine is off or at low idle; 3. To act as a voltage stabilizer for the vehicle's electrical system; 4. To store excess electrical energy generated by the alternator. Methods for maintaining a car battery include: 1. Cleaning the white acid corrosion powder accumulated on the battery terminals to extend its service life; 2. Adding distilled water to the level between the upper and lower indicator lines; 3. Checking whether the battery is charging normally.
