The methods to handle a dead car battery that prevents the engine from starting are: 1. Use a charger to replenish the battery with a low current over a long period; 2. Find a rescue vehicle and connect the battery electrodes of both cars using jumper cables, then start the rescue vehicle to charge; 3. Increase the voltage of the repair machine to above 10V for charging. The functions of a car battery are to store and supply electricity. Its maintenance methods include: 1. Avoid parking the car in an open parking lot for extended periods; 2. Avoid multiple uninterrupted starts; 3. Regularly check the accessories and connecting circuits on the battery; 4. Do not use car electronics after turning off the engine.
That time my car battery died in the parking lot, I managed to jump-start it. I asked a friend for help - we parked our cars nose-to-nose. I took the red clamp and attached it to the positive terminal of the working battery, then connected the other end to my battery's positive terminal. Next, I used the black clamp to connect the negative terminal of the good battery to a metal part of my car's engine block. After starting my friend's car first and waiting two minutes, my car fired up immediately. After starting, don't rush to leave - rev the engine for about ten minutes to let the alternator recharge the battery. I recommend keeping a portable jump starter in your car, one about the size of a power bank, so you won't panic next time even if there's no help available late at night. However, if your battery is over three years old and keeps losing charge, it's best to replace it as soon as possible.
