What are the effects of insufficient battery power on a car?

[Myrtle]

Insufficient battery power can have the following effects on a car: 1. It affects the starting circuit, making it prone to overheating; 2. Insufficient voltage causes the starter to respond too slowly during startup, which can damage the starter switch and flywheel over time; 3. Prolonged low voltage will shorten the battery's service life. The functions of the battery are: 1. When starting the engine, the battery supplies power to the starting system, ignition system, and electronic fuel injection system; 2. When the engine is off or idling at low speed, it provides power to the car's electrical equipment; 3. When the generator's output is insufficient, it can assist in supplying power to the electrical equipment; 4. It mitigates voltage surges in the electrical system, protecting the car's electronic devices; 5. It can store excess electricity generated by the alternator.
