What is the method to check the battery level of a vehicle?

[SanThomas]

To check the battery level of a vehicle, you can: 1. Observe the color of the battery indicator to understand its status; 2. Use a multimeter to measure the battery voltage; 3. Check the remaining battery level on the car's dashboard. Methods for battery maintenance include: 1. Charge the battery promptly when the ammeter shows insufficient power; 2. Adjust the electrolyte density according to standards based on different regions and seasons; 3. Add distilled water or special replenishing fluid when the electrolyte is low; 4. Limit each engine start to no more than 5 seconds; 5. Start the car periodically if the battery is unused for a long time; 6. Regularly check if the small holes on the battery cover are ventilated; 7. Inspect the battery terminals for oxidation; 8. Examine all parts of the circuit for signs of aging or short circuits.
