How to jump-start a battery
A dead battery is another common inconvenience that many drivers will encounter in their lifetime. And unlike changing a flat tire, this one requires a little help from your friends. So, if you don't want to call a tow truck and you have a willing helper.
Here's how to get some life back in your car battery.
- Open both vehicle hoods and locate the batteries.
- Remove any terminal covers and corrosion.
- Attach the positive (red) jumper cable to the positive (red) terminal of the dead battery. Make sure that both metal clamps are firmly in contact with the terminal.
- Attach the other end of the positive (red) jumper cable to the positive (red) terminal of the assisting battery.
- Attach the negative (black) jumper cable to the negative (black) terminal of the assisting battery.
- Attach the remaining end of the negative (black) jumper cable to an exposed metal part of the disabled vehicle's engine, away from the battery and the carburetor/fuel-injection system.
- Start the assisting vehicle's engine.
- Start the disabled vehicle's engine.
- Allow both vehicles to run connected for about three minutes.
- While leaving the jumpstarted vehicle running, disconnect the cables in the reverse order that they were attached and close the hoods.
- Keep the jump started vehicle's engine running for about a half hour to allow the battery to fully charge.
