What to Do When the Car Battery Is Completely Dead?

[DeDelaney]

When the car battery is dead, the only solution is to jump-start it using another battery. Connect the positive terminal of the other car's battery to the positive terminal of your car's battery, and then connect the negative terminal to the negative terminal. Here are the detailed steps: 1. If the battery suddenly dies, contact a rescue vehicle and connect jumper cables to temporarily charge the battery and start the engine. To avoid being unable to charge when the battery is dead, it is advisable to keep a set of jumper cables in the car. 2. When connecting the jumper cables, be very careful not to reverse the order: first connect the positive terminal of the dead battery to the positive terminal of the rescue vehicle's battery, then connect the negative terminal of the rescue vehicle's battery to a metal part in the engine compartment of the dead car (grounding). 3. After connecting the jumper cables, start the rescue vehicle's engine and slightly increase the RPM. After about 5 minutes, the dead battery will receive an emergency charge. Once charging is complete, remove the jumper cables in the reverse order of connection.
