2 Answers
The solutions for a car that won't start due to dead battery are: 1. Use a battery charger to slowly recharge the battery with low current over an extended 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 device 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 outdoors for extended periods; 2. Avoid repeatedly starting the car without intervals; 3. Regularly check the battery accessories and connection lines; 4. Do not use car electronics after the engine is turned off.
Last time my car wouldn't start after being parked at the airport for a week, and I was in a panic. Quickly grabbed the emergency jumper cables and borrowed power from a kind stranger's car nearby. Remembered to connect the red clamp to my battery's positive terminal first, then to theirs; black clamp to their negative terminal, and finally to my car's metal frame. Started the rescue car and revved the engine for five minutes before attempting to start mine - fired right up. Made sure not to turn off the drained car, driving at least half an hour to recharge. Later bought a smart battery monitor that clips onto the negative terminal - can check health status via phone. Haven't faced this hassle since replacing the battery every three years.
