What to Do When the Car Battery Is Completely Dead?

[Selena]

If the battery is dead, you can call a friend to come over and give you a jump start. Jump starting requires jumper cables; if you don't have any, you can borrow them from a nearby auto repair shop. Here are some relevant details about car batteries: 1. The battery is a very important component of a car. When the engine is not running, the battery powers the vehicle's electronic devices and is also responsible for starting the engine. 2. When starting the engine, the starter needs to turn, the ignition system needs to spark, and the fuel system needs to build oil pressure—all of which require electricity. 3. If you don't drive for a long time, it is recommended to disconnect the negative terminal of the battery to prevent it from draining. If the car is left unused for an extended period, take it out for a short drive occasionally to allow the alternator to recharge the battery. 4. During winter nights, try to park the car in an underground parking lot or your own garage to protect the battery. The low outdoor temperatures in winter can reduce the battery's lifespan if the car is left outside overnight, and it may cause difficulty starting the engine the next morning.
