1 Answers
To determine if a car battery needs replacement, consider the following situations: 1. Inspect the battery's appearance - if there is bulging or deformation on both sides of the battery, or if white or green powdery substances appear on the battery terminals, replacement is needed; 2. Check the power indicator color - green indicates sufficient power, black indicates the need for charging, and white indicates the battery needs replacement; 3. Measure the battery voltage - if the no-load voltage of the battery is below 9 volts, replacement is required. The functions of a car battery are: 1. To supply power to the starting system, ignition system, electronic fuel injection system, and car electrical appliances when starting the engine; 2. To provide power to the car's electrical equipment when the engine is stopped or idling at low speed; 3. The car battery acts as a voltage stabilizer for the entire vehicle's electrical system; 4. The car battery stores excess electricity generated by the alternator.
