Jump starting a car typically takes about 10 to 15 minutes from start to finish. Here is the general timeline and process:

• Preparation: Park the vehicle with the good battery close to the dead car, turn off both vehicles, and ensure batteries are clean and terminals accessible. This usually takes a few minutes

• Connecting jumper cables: Attach the red (positive) cable to the positive terminals and the black (negative) cable to the negative terminals or a grounded metal surface on the dead car. Be careful to avoid sparks

• Charging the dead battery: Start the engine of the vehicle with the good battery and let it idle for about 2 to 5 minutes to transfer some charge to the dead battery. If the dead car doesn’t start immediately, let the donor car run for up to 10-15 minutes before trying again

• Starting the dead car: Attempt to start the dead car. If it starts, leave it running for at least 20 minutes or take it for a short drive to recharge the battery fully

• Disconnecting cables: Remove the jumper cables in reverse order and safely store your equipment

If the car does not start after 15 minutes of charging, the battery may be too damaged or another issue may exist

. In summary, the jump-start process usually takes around 10-15 minutes, including waiting time for the battery to gain enough charge to start the engine

. After a successful jump, driving the car for at least 20 minutes is recommended to recharge the battery fully
