Can You Defibrillate Someone With a Car Battery?

Defibrillation is a medical procedure that uses electrical shock to restore the heart’s normal rhythm. It is commonly used in emergency situations where the patient’s heart has stopped or is beating irregularly. In such cases, time is of the essence, and any delay in treatment can be fatal. This raises the question, can you defibrillate someone with a car battery?

Could you restart someone’s heart with a car battery?

The answer is yes, technically, you could restart someone’s heart with a car battery. However, we strongly advise against it. Car batteries deliver a high voltage that can cause serious burns, and the shock could damage the heart further, leading to permanent injury or death.

Moreover, car batteries are not designed for medical use, and the voltage they produce is not regulated. Defibrillators, on the other hand, are specifically designed for medical use and deliver a regulated electrical shock that is safe for the patient.

Can you jump a car with a defibrillator?

No, you cannot jump-start a car with a defibrillator. Defibrillators are designed to deliver a high-voltage shock to the heart, not to power a car. Attempting to use a defibrillator to jump-start a car could damage the device and render it useless in an emergency medical situation.

Can you bring someone back to life with jumper cables?

No, you cannot bring someone back to life with jumper cables. Jumper cables are designed to transfer electrical power from one car battery to another to start the engine. They are not designed to deliver the high-voltage shock required for defibrillation.


It is essential to understand that defibrillation is a serious medical procedure that should only be performed by trained professionals. While it may be tempting to try unconventional methods in an emergency situation, doing so could be dangerous and potentially fatal.

If you are ever in a situation where someone requires defibrillation, stay calm, call for emergency medical services, and follow their instructions. Remember, time is of the essence, and any delay in treatment can be life-threatening. Always prioritize safety and leave the medical treatment to trained professionals.
