To begin, connect the car to the dead battery using the jumper wires. Both cars’ ignitions must be turned off. Also, their parking brakes must be set to park or neutral.

Secondly, Remove any battery terminal covers by opening the hood or trunk. Clean the connectors with a wire brush cleaner if they have powdery oxidation.

Thirdly, Clamp the red positive (+) cable to the red positive (+) battery terminal on the disabled vehicle.

After that, connect the opposite end of the red positive (+) line to the red positive (+) battery terminal.

Then, connect the black negative (-) clamp to the black negative (-) battery connection.

Next connect the black negative (-) cable’s opposite end to a metal surface distant from the battery. Make sure the cables don’t have any moving parts.

Further, start the booster vehicle after a final inspection. Then try to start the car that has been disabled. Most of the time, it should start. However, it may need to be charged for a few minutes first. 

Now, disconnect the cables in the opposite manner that they were connected. Then close the hoods without shutting off the power of the jump-started vehicle.

Finally, allow the jump-started vehicle’s engine to run for several minutes.

However, when jump-starting the battery you have to take proper precaution. Otherwise getting exposed to lead can lead to serious problems like nausea.
