At What Voltage Will a Car Battery Fail to Start the Engine?
1 Answers
When a car battery's voltage drops below 12V, it may result in failure to start or difficulty in starting the engine. Specific details regarding the voltage at which a car battery fails to start the engine are as follows: 1. If the car battery voltage is too low, there won't be sufficient starting current to power the starter motor. Without the starter motor functioning, the car will fail to start. 2. Each attempt to start the car should not exceed 5 seconds to avoid damaging the battery. If the car doesn't start after several attempts, check the ignition system and battery voltage instead of repeatedly trying to start it. 3. If the vehicle remains unused for an extended period, ensure the battery is fully charged beforehand. It's advisable to start the vehicle at least once a month.
