The solutions for a dead battery that won't start the car are: 1. Jump-start method; 2. Push-start method; 3. External force towing start. The maintenance methods for the battery are: 1. Start the car regularly to charge the battery; 2. Add distilled water or special replenishing fluid when the electrolyte is insufficient; 3. Frequently check if the small holes on the battery cover are ventilated during daily driving; 4. Check for signs of oxidation on the positive and negative terminals of the battery; 5. Inspect all parts of the circuit for aging or short circuits; 6. Turn off all electrical devices when leaving the car. The functions of the battery are: 1. When starting the engine, the battery supplies power to the starting system, ignition system, and electronic fuel injection system; 2. When the engine is stopped or idling at low speed, it provides power to the car's electrical devices; 3. When the generator's output is insufficient, it can assist in supplying power to the electrical devices; 4. It mitigates impact voltage in the electrical system, protecting the car's electronic equipment; 5. It can store excess electricity generated by the alternator.
Last time my car battery died and I couldn't start the engine, it was so frustrating. In the end, a friend helped with jumper cables: we parked the two cars close together, connected the red cable to the positive terminal and the black cable to the negative terminal, started his car and waited for a while, then tried starting mine and it worked. After starting, I drove for about half an hour to let the alternator recharge the battery. If the battery is too old, say four or five years, it might need replacement. Usually, pay attention not to leave the car parked for too long without moving, as it can drain the battery; also check if the lights, radio, etc. are properly turned off to avoid power leakage. Problems with the alternator can also prevent full charging, so it's recommended to have the voltage checked during regular maintenance to keep it within the normal range.
