What to Do When Your Car Has No Power?

[MacJayce]

The methods to deal with a car that has no power are: 1. Jump-starting with jumper cables; 2. Push-starting the car; 3. Starting with external force traction. The reasons for a car having no power are: 1. The car has been parked for a long time, causing the battery to lose power; 2. The battery has reached its service life; 3. Insufficient battery electrolyte or leakage; 4. A blown fuse causing the battery to lose power; 5. Corrosion of the battery terminals; 6. Engine damage. The methods to maintain the car battery are: 1. Develop good in-car electricity usage habits; 2. Regularly drive at high speeds for long distances; 3. Do not leave the car unused for extended periods; 4. Do not connect high-power electrical appliances directly to the battery.

That weekend, I was planning to take the whole family on a countryside trip. As soon as I got in the car, the dashboard went completely black, and my heart sank. I quickly asked a neighbor for help to jump-start the car. I always keep emergency jumper cables in my car—red clamp on my battery’s positive terminal and black clamp on the metal part of the other car’s body. Keeping the rescue car’s engine running at 2000 RPM, my car finally roared to life after five minutes, and I immediately drove to the auto repair shop for a check-up. The mechanic said car batteries typically last only three to four years, especially prone to draining in winter. Leaving lights slightly on or doors not fully closed can also drain the battery. Now, I’ve developed the habit of turning off the AC and radio before shutting off the engine and even installed a mobile app to monitor the battery’s health in real time.

Last week after overtime, I found my car completely dead, not even the central locking would work. I looked up 24-hour rescue services nearby on my phone, and the technician arrived in ten minutes with a portable power source. He taught me to first open the hood and check the battery terminals—white crystals indicated acid leakage, meaning the battery needed replacement. He suggested keeping an emergency jump starter in the trunk, about the size of a cigarette box, which can be plugged into the cigarette lighter. He also advised against using high-power appliances when the engine is off. I had left my car air purifier on overnight, which drained the battery completely. Now, I have the car wash check my battery voltage every month, and I make sure to get it inspected before winter.

Coming out of a convenience store late at night to find my car lights automatically on and draining the battery, with my phone almost dead too, was really frustrating. I called the insurance company's free rescue hotline. While waiting, I managed to search with weak signal and found a few clever tricks: older cars can be opened with a mechanical key; some cars have a physical start switch near the steering column; never force charge an electric car when it's out of power, as it might blow a fuse. The rescue technician helped me jump-start the car using jumper cables with a voltage display, and advised keeping the RPM up while driving to charge the battery. He mentioned that cars with start-stop functionality require AGM-specific batteries, as regular ones won't last more than six months.
