Can idling the car charge the battery?

[SanElliott]

Idling the car can indeed charge the car battery. Once the engine is started, the alternator begins to operate, which then charges the battery. The battery is a crucial component in a vehicle used for storing electrical energy. Without it, the car cannot function properly. As a wearable part, the battery requires periodic replacement. Its performance degrades with increasing charge-discharge cycles, necessitating regular replacement. Under normal circumstances, a battery can last 3 to 4 years. During maintenance, owners can ask technicians to check the battery's voltage and internal resistance with a multimeter. If these values fall below the specified thresholds, it indicates the battery needs replacement. When replacing the battery, it's essential to purchase a product with the same specifications as the original car battery, so always verify the original battery's specifications.
