Typically, car batteries are 12 volts. The batteries used in cars are lead-acid batteries, which consist of 6 cells connected in series. Each cell has a voltage between 1.7 to 2.1 volts. The lifespan of a household car battery is approximately 27 months, but the actual lifespan depends on the vehicle's usage conditions. The battery's lifespan is significantly influenced by driving habits. For instance, frequent aggressive driving can shorten the battery's lifespan, so developing good driving habits is crucial. During vehicle usage, it's important to maintain the car battery. The battery supplies power for ignition and supports various electrical devices in the car, including many high-power ones. Before turning off the engine, always ensure all electrical devices are switched off to prevent excessive battery drain, which could affect normal vehicle operation.
