A dead car battery is a common problem, especially during the winter months. If you find yourself in this situation, there are a few things you can do to try to revive the battery and get your car back on the road.
Tips for Reviving a Dead Car Battery
1. Check the battery connections.
The first thing you should do is check the battery connections to make sure they are clean and tight. Loose or corroded connections can prevent the battery from holding a charge.
To clean the connections, use a wire brush or a battery terminal cleaner. After you clean the battery terminals, screw them in tightly.
2. Jump-start the car.
If the battery connections are clean and tight, but the car still won’t start, you can try to jump-start it. To do this, you will need a pair of jumper cables and another car with a working battery.
Connect the positive jumper cable to the positive terminal of the dead battery and the negative jumper cable to the negative terminal of the other battery. Then, start the other car and let it run for a few minutes.
Once the other car has been running for a few minutes, try to start your car. If your car starts, disconnect the jumper cables in the reverse order that you connected them.
3. Charge the battery.
If you can’t jump-start the car, you may need to charge the battery. To revive the battery, you will need a battery charger. Connect the battery charger to the battery and follow the instructions on the charger to charge the battery. Once the battery is charged, try to start the car.
4. Replace the battery.
If you have tried all of the above and the car still won’t start, it is possible that the battery needs to be replaced. If the battery is more than three years old, it is probably time to replace it.
DIY Repair Tips
If you are comfortable working on cars, there are a few DIY repair tips you can follow to try to revive a dead car battery or to troubleshoot a car battery that is showing signs of a bad car battery.
1. Check the alternator.
The alternator is responsible for charging the battery. If the alternator is not working properly, the battery will not hold a charge. To check the alternator, you can use a multimeter to measure the voltage at the battery terminals.
The battery should have a voltage of between 13 and 14 volts. If the voltage is lower than 13 volts, the alternator may need to be replaced.
2. Check the starter solenoid.
The starter solenoid turns on the starter motor. If the starter solenoid is not working properly, the starter motor will not engage and the car will not start.
To check the starter solenoid, you can use a jumper cable to connect the positive battery terminal to the starter solenoid terminal. If the starter motor engages, the starter solenoid is working properly. If the starter motor does not engage, the starter solenoid may need to be replaced.
3. Clean the battery terminals.
As mentioned above, loose or corroded battery terminals can prevent the battery from holding a charge. To clean the battery terminals, use a wire brush or a battery terminal cleaner. After you clean the battery terminals, screw them in tightly.

- Can you bring a car battery back from the dead?
