At what voltage does a car battery fail to start the engine?
1 Answers
Car batteries with a voltage below 11V may fail to start the engine. Precautions for using car batteries include: 1. Avoid parking the car in open-air parking lots for extended periods; 2. Avoid multiple consecutive startup attempts; 3. Regularly inspect battery components and connection circuits; 4. Do not use car electronics after the engine is turned off. Car batteries, also known as storage batteries, operate by converting chemical energy into electrical energy. Their functions are: 1. Providing power to the car's starter and ignition system; 2. Supplying stable DC power to car electronics; 3. Mitigating impact voltage in the system to protect electronic equipment; 4. Storing excess electricity generated by the alternator.
