What is the minimum starting voltage for a car battery?
1 Answers
Car battery starting voltage should not be lower than 12.2V. Below this value, it becomes difficult to start the engine. Normal battery replacement cycle: When a car is equipped with its original battery, the correct service life is 3-4 years. If the battery is still functioning normally, replacement is unnecessary. Consider replacing the battery only if it fails to start the engine properly or cannot hold a charge. Signs indicating battery replacement is needed: The battery status indicator light comes on, the vehicle is harder to start than usual (requiring multiple ignition attempts), or when idling during night driving, insufficient battery life results in inadequate power supply for proper lighting, causing noticeable dimming of headlights.
