Eventually most car owners have to face jump starting other vehicles or needing their vehicle jump started due to battery issues. Oftentimes when car batteries die all they need is a quick electrical recharge from another vehicles battery to return to normal. Reasons for dead car batteries range from leaving on interior and exterior lights to extreme temperatures. Follow along below this month as we describe step-by-step how to jump start a car’s battery.

Items You Will Need

• Jumper Cables
• Gloves
• Owner’s Manual

Important Tips

• Read your owner’s manual first. Your manufacturer may advise against jump starting a vehicle due to sensitive electronic circuitry.
• Don’t try to jump a frozen battery.
• Do NOT jump a battery that is cracked or leaking. This is very dangerous. You will need to purchase a new battery at this point, so call a tow truck or a friend that can help you out.

Step 1: Park vehicles close together so that the jumper cables will easily reach both batteries. Turn off both engines, put on gloves, and properly lock both vehicle’s engine hoods in their upright positions. Remove any tangles from the jumper cables and be sure to not let any of the four metal ends touch one another.

Step 2: Once you’ve located the batteries (check owner’s manual if not sure), identify the two post “terminals”. One is positive (+) and usually red while the other one is negative (-) and usually black. Remove any plastic or rubber protecting the terminals so that you expose the metal beneath.

Step 3: Grab one of the POSITIVE (red) clamps on the jumper cables and attach it to the dead car’s positive terminal post (+ or red). The clamps should have metal teeth that help them grip the terminal post.

Step 4: With both vehicles still turned off, take the POSITIVE (red) clamp at the opposite end of the cables and attach it to the positive terminal post of the good, working battery.

Step 5: Take the NEGATIVE (black) clamp on that same end and attach to the negative terminal of the good, working battery.

Step 6: Take the final NEGATIVE (black) clamp and attach it to negative terminal of the car that is being jump-started.

Step 7: Triple check that all negative and positive terminals are correctly connected before starting the vehicle of the car with the good, working battery. Allow the vehicle to run this way for 3-5 minutes. You can now try to start the dead car as normal. If the engine does not start allow the battery to charge for several more minutes before trying again. At this point both cars should be on and running successfully.

Step 8: Working in reverse order, unhook each of the clamps from the terminals without ever letting the ends touch one another. Safely store jumper cables, remove gloves, and return engine hoods to their normal positions.
