What are the solutions when the car battery is dead and the car won't start?

When the car battery is dead and the car won't start, you can replace the car battery or use jumper cables to transfer power. Here are some maintenance methods for car batteries: 1. In-car electricity usage: To maintain the car battery, avoid activities like listening to the radio loudly, charging mobile phones, or using air pumps when the engine is off. Prolonged use of these features can drain the battery, and frequent depletion significantly reduces the battery's lifespan. 2. Long-distance highway driving: Regular highway driving has many benefits. It not only helps remove carbon deposits from the vehicle but also fully charges the battery. Generally, driving on the highway for more than an hour can fully charge the car battery, keeping it in optimal condition. 3. Avoid prolonged vehicle inactivity: If the car won't be used for an extended period, disconnect the battery cables or start the vehicle every two weeks and drive several dozen kilometers to ensure the battery remains functional. 4. Connection of high-power electrical devices: Many modern car accessories, such as car refrigerators, vacuum cleaners, and air pumps, have high instantaneous power consumption. Avoid powering these devices directly from the car battery. Instead, start the vehicle first before connecting any electrical equipment.
My car also experienced a dead battery before, and the most straightforward solution is to get a jump start from another vehicle. You'll need a pair of jumper cables - connect the red clamp to the positive terminals of both batteries, then attach the black clamp first to the negative terminal of the donor car, and the other end to a metal part of the stalled car's frame (avoid connecting directly to the negative terminal). After starting the donor car, wait a few minutes before attempting to ignite the stalled vehicle. Regular battery maintenance is crucial - avoid keeping lights or electronics on after turning off the engine, and replace batteries older than three years preemptively. I always keep a compact emergency jump starter (about the size of a matchbox) in the glove compartment - it's incredibly useful in emergencies, especially during winter when low temperatures make batteries more prone to failure.
