What to Do When Your Car Battery Dies and the Car Won't Start?

The solutions for a car that won't start due to a dead battery are: 1. Push-starting the car if it's a manual transmission; 2. Using jumper cables to connect two cars and charge the battery; 3. Using a car-specific power bank to charge the battery. The functions of a car battery include: 1. Assisting the generator in supplying power to electrical devices when the generator is overloaded; 2. Providing power to electrical devices when the generator is not producing electricity or the voltage is low; 3. Converting part of the electrical energy into chemical energy for storage. Methods for maintaining a car battery are: 1. Avoid excessive discharging; recharge the battery promptly if it has been excessively discharged; 2. Disconnect the battery if the vehicle will not be used for an extended period; 3. Prevent short circuits in the battery; 4. Regularly check the connections to ensure they are secure and the terminal surfaces are clean for good contact; 5. Never place metal tools or conductive objects near the battery terminals to avoid short circuits.
The other day I also experienced a dead battery situation - this kind of trouble requires patience. The safest method is to find another car for jump-starting assistance, just prepare two battery jumper cables. Connect positive to positive, negative to negative (never reverse the connections), then let the rescue car run for a few minutes before attempting to start. If no help is available, old manual transmission cars can try push-starting - put it in second gear, depress the clutch, have people push the car, then suddenly release the clutch. It's wise to keep an emergency jump starter in the trunk; spending about a hundred yuan can prevent being stranded roadside. Once during winter in the suburbs when my battery died, this device saved me. Final reminder: car batteries typically last only 3-4 years, so regular voltage checks are essential.
A sudden dead battery can be really annoying, especially when you're in a hurry. I once encountered this when rushing to work, and since then I've made it a habit to keep jumper cables in my car. The jump-start process is actually quite simple, but safety is crucial: first turn off both vehicles, connect the red cable to the positive terminals of both batteries, attach the black cable to the negative terminal of the donor car first, then connect the other end to the metal frame of the dead car (not its battery negative). Start the donor car, wait a few minutes to allow charging, then try starting the dead vehicle. If jump-starting fails, the battery might be completely dead and need replacement. Remember not to turn off the engine immediately afterward - drive for at least half an hour to let the alternator recharge it. Regularly check the battery inspection window's color change - when it turns black, it's time for a replacement.
