How To Jump Start a Car’s Dead Battery

Step 1: LOCATE JUMPER

If you heeded the advice in our last article about items to keep in your car for winter, then you probably already stored a set of JUMPER CABLES in your vehicle. To any of the stragglers, you will have to find someone who has a set of jumper cables and is willing to spend the time giving your car’s battery a jump.

Step 2: PREPARE VEHICLES

After you locate jumper cables and another car with a charged battery, align the vehicles close enough together for the cables to reach each battery. Next, SHUT OFF the ignition to both vehicles and make sure they’re both in PARK. Then, pop both hoods and LOCATE the positive (+/POS) sign on the batteries (usually under a red rectangular covering).

Step 3: ATTACH JUMPER CABLES

After attaching the first jumper cable, BE CAREFUL to NOT touch any of the clamps to each other (to prevent electric shock).

1. Attach RED cable clip to the POSITIVE (+) terminal of the CHARGED battery
2. Attach BLACK cable clip to the NEGATIVE (-) terminal of the CHARGED battery
3. Attach other end of RED cable clip to the POSITIVE (+) terminal of the DEAD battery
4. Attach BLACK cable clip to a motionless, unpainted METAL SURFACE away from the battery

Step 4: IGNITION  

After securing the jumper cables, START the ignition of the CHARGED battery’s car. Rev the engine slightly by gently tapping the gas pedal to SPEED UP the charge. After a few minutes, START the ignition of the DEAD battery’s car and, with luck, the battery will be live.

Step 5: DRIVE

After jumping the dead battery, DRIVE around for at least 15 minutes before shutting off the engine. This will help ensure it’s holding the charge. Enjoy and be safe this winter! If you have any troubles, contact Brothers Collisions & Mechanical for all of your auto mechanic needs in Rochester!
