What is the normal starting voltage for a car?

[LaKhloe]

The normal starting voltage for a car should not be lower than 12.1V. Under normal circumstances, the battery voltage before starting the car ranges between 11.8V and 12.8V, while the battery voltage after starting ranges between 13.2V and 14.8V. When the car's engine is not running, the battery voltage should be between 12.2V and 12.8V. If it drops below 11.6V, starting the car becomes difficult, and it is advisable to turn off other electrical appliances. When the battery voltage falls below 10V, the car generally cannot be started. During the use of a car battery, it is essential to keep the battery clean and dry while ensuring the vent holes remain unobstructed. Avoid continuous use of the starter; each attempt should not exceed 5 seconds, with a 10 to 15-second rest between attempts. A battery filled with electrolyte should not be left in a state of insufficient charge for extended periods and must be charged regularly to prevent damage. The electrolyte level should be 10 to 15mm above the plates; if the level is too low, add distilled water promptly, not additional electrolyte.
