How to Properly Jump a Dead Car Battery

Jumper Cables on a Dead Battery

So you’re out and about running errands, everything seems fine and all of a sudden the unthinkable happens. Your car battery dies. Relax, no need to panic, the process of jumping a car is actually a lot more simple than you would think. Just follow these instructions and you will still make it home for dinner.

First Things First

Now you will need a second car with a working battery before you can get anything done, plus jumper cables to create a line between the two that will charge your dead battery. Any car will do, so you don’t have to worry about difference in make or model, but unless you can summon lightening, the second car is a must. Also before you even start considering connecting anything to any part of either car, establish which handles of the jumper cables are positive, and which are negative. This bit is important to know unless you want an electrical meltdown along with your emotional one.

So now that you’ve gotten the proper equipment and a buddy to see you through your sorrows, let’s continue.

Making a Connection

First of all you need to make sure that both cars are OFF. Read that one more time as it is very important, both cars need to be off before you attach either of the clamps.

Now, see if the battery is visible under your hood, if not don’t worry everything is going to be alright. Look under the hood for what is called the positive post, it has a red cap on it. Unscrew the cap and attach the red (the POSITIVE end) cable. After you accomplish this, pick up the black (the NEGATIVE end) cable to the negative post which usually has a black cap. If you cannot find a negative post, then you must find a ground source. That means attach the negative cable to the metal frame or part of the body of the car that is metal.

If the battery under your hood IS visible, the same rules apply, put the positive cable with the positive post and the negative cable with the negative post or attach it to a metal part of your car as a ground source.

Now that you have accomplished this, it’s time to turn your attentions to the second car. Do the exact same thing. Remember when I said know which is positive and which is negative, this is extremely important at this juncture. Do not cross the lines, you are not a Ghost buster. Positive goes with positive, and negative with negative.

Now on the off chance that the colors are different, there are other ways to check what kind of cable you have. One cable is marked with a “+” that is the positive cable. The cable with a “-” is the negative. Do not get these mixed up please.

Charging Ahead

You successfully hooked up the cars, all that’s left now is to turn on the car with the good battery. Allow it to charge the bad battery until you can start your car!
