Does Revving Your Engine Help Jump a Car?
If your car battery dies, you may be wondering if revving your engine will help jump-start it. The answer is: no.
Why Revving Your Engine Doesn’t Help
When you rev your engine, you are increasing the speed at which the engine is running. This does not provide any additional power to the battery or starter motor. In fact, it can actually make it more difficult to jump-start your car.
When you rev your engine, the alternator is forced to work harder to keep up with the increased demand for electricity. This can put a strain on the alternator and shorten its lifespan.
Additionally, revving your engine can cause the battery to overheat. This can damage the battery and make it more difficult to hold a charge.
What to Do Instead
If your car battery dies, the best thing to do is to call for roadside assistance or have a friend or family member jump-start your car. If you are unable to do either of these things, you can try the following:
- Turn off all unnecessary electrical devices, such as the headlights, radio, and air conditioner.
- Put the car in neutral or park.
- Connect the jumper cables to the dead battery and the donor car’s battery.
- Start the donor car and let it run for a few minutes.
- Try to start your car.
If your car does not start after a few minutes, stop trying and call for roadside assistance.
Conclusion
Revving your engine does not help jump-start a car. In fact, it can actually make it more difficult. If your car battery dies, the best thing to do is to call for roadside assistance or have a friend or family member jump-start your car.
