Solutions when a car battery is dead and won't start include: 1. Jump-starting the car; 2. Push-starting the car; 3. Using an external towing method to start the car. Battery maintenance methods are: 1. Start the car periodically to charge the battery; 2. Add distilled water or a special replenishing fluid when the electrolyte level is low; 3. Regularly check if the vent holes on the battery cover are clear; 4. Inspect the battery's positive and negative terminals for signs of oxidation; 5. Check all parts of the circuit for aging or short circuits; 6. Turn off all electrical devices when leaving the car. The functions of the car battery are: 1. Providing power to the starting system, ignition system, and electronic fuel injection system when starting the engine; 2. Supplying power to the car's electrical devices when the engine is off or idling at low speed; 3. Assisting in powering electrical devices when the alternator's output is insufficient; 4. Absorbing voltage spikes in the electrical system to protect the car's electronic devices; 5. Storing excess electricity generated by the alternator.
Once my car battery was dead and couldn't start, which was really frustrating. I immediately called a friend to come over with their car to help jump-start mine. The process goes like this: turn off both vehicles, use jumper cables - connect red to positive terminals, black to negative terminals or bare metal on the chassis. Then start the friend's car with engine running, and try starting my car. If it starts, let it idle for about half an hour to recharge. If it still doesn't work, the battery might be too old or there could be alternator issues - then it's time to visit a repair shop for replacement. For prevention, I've developed the habit of checking lights and AC are off before parking; for long-term parking, start the engine weekly for 10 minutes to recharge. After that incident, I bought a portable jump starter to keep in the car - very convenient for emergencies.
