To jump start a car battery, expose the dead and working batteries, connect them with jump leads, start the working car, wait one minute, start the other car, wait several minutes, and unlink the batteries. This 45-minute procedure requires jump cables and a car with a working battery.
- Expose the batteries
Put the vehicle with the dead battery in neutral, shut it off, and take the key out of the ignition. Expose the battery. Park the vehicle with the working battery several feet away, put it in neutral, and turn it off. Expose the working battery.
- Connect the jump leads
Connect one end of the red jump lead to the positive terminal of the working battery, and connect the other end to the positive terminal of the dead battery. Connect the black jump lead to the negative terminal of the working battery, and then clip the other end to a metal object not connected to the dead battery.
- Start the vehicles
Start the working vehicle, wait 60 seconds, and then start the vehicle with the dead battery. If it does not start, wait another minute, and try again. Leave both vehicles running for several minutes.
- Remove the jump leads
Disconnect the jump leads, and close the vehicle hoods. Drive the jumped vehicle for at least 30 minutes.
