- Set the parking brake on both vehicles
- Put both vehicles in neutral or park gear
- Turn off the engine, lights, and any accessories in both vehicles
Connecting The Jumper Cables
Now it’s time to connect the jumper cables:
- Attach one end of the positive (red) jumper cable to the positive terminal of the dead battery
- Attach the other end of the positive (red) jumper cable to the positive terminal of the good battery
- Attach one end of the negative (black) jumper cable to the negative terminal of the good battery
- Attach the other end of the negative (black) jumper cable to a metal surface on the dead vehicle’s engine or frame, away from the dead battery
Starting The Working Vehicle
Now it’s time to start the working vehicle:
- Turn the key to start the engine of the working vehicle
- Allow the engine to run for a few minutes to charge the dead battery
Starting The Dead Vehicle
With the working vehicle’s engine running, it’s time to try starting the dead vehicle:
- Turn the key to start the engine of the dead vehicle
- If the engine doesn’t start, allow the working vehicle’s engine to run for a few more minutes and try again
The Big Question: How Long Does A Dead Battery Take To Jump?

On the other hand, if the dead battery is old or severely discharged, it may take 30 minutes to an hour or more to jump-start.
What Happens During The Jump-Starting Process?
During the jump-starting process, the good battery provides a temporary power source to the dead battery. The electrical current flows from the good battery to the dead battery, allowing the dead battery’s chemical reactions to restart.
As the dead battery begins to recharge, the voltage starts to rise, and the system begins to stabilize. This process can take anywhere from a few minutes to several hours, depending on the extent of the dead battery’s discharge.
After The Jump: What’s Next?
Once the dead vehicle’s engine is running, it’s essential to:
Remove The Jumper Cables
Disconnect the jumper cables in the reverse order that they were attached:
- Remove the negative (black) jumper cable from the metal surface on the dead vehicle’s engine or frame
- Remove the negative (black) jumper cable from the negative terminal of the good battery
- Remove the positive (red) jumper cable from the positive terminal of the good battery
- Remove the positive (red) jumper cable from the positive terminal of the dead battery
Recharge The Dead Battery
Drive the dead vehicle for an extended period to recharge the battery. It’s recommended to drive for at least 30 minutes to an hour to allow the battery to recharge fully.
Check The Electrical System
Have the electrical system checked by a professional mechanic to ensure there are no underlying issues that caused the battery to die in the first place.
Conclusion
Jump-starting a dead battery can be a lifesaver when you’re stranded with a dead car. While the process may seem daunting, following the proper procedures and understanding the underlying principles can make all the difference.
In conclusion, the time it takes to jump-start a dead battery depends on various factors, including the age and condition of the dead battery, the capacity of the good battery, and the extent of the dead battery’s discharge. On average, it can take anywhere from 15-30 minutes to jump-start a dead battery. However, with the right knowledge and equipment, you can get back on the road in no time.
Remember to always follow proper safety protocols, and if you’re unsure about any part of the process, don’t hesitate to seek help from a professional mechanic or roadside assistance service.
How Long Does It Take To Jump-start A Dead Battery?
It typically takes around 15-30 minutes to jump-start a dead battery, assuming the dead battery is not damaged beyond repair and the good battery is in good condition.
