Do You Know how to Jump Start a Dead Battery?

Prior to jump starting an automobile, take a few minutes to collect some data. Peruse your motor vehicle’s owner’s handbook, in particular any segments associated to jump starts or your vehicle battery. Some car makers advise not jump starting the vehicle, or several may give you specific directions associated to your vehicle. Be for sure you understand where your vehicle’s battery is located.

Locate the Battery

In nearly all cars, it is in the front end of the vehicle. It would be beneath the hood alongside the engine. But then again, in some vehicles, the battery is in the trunk of the car. Frequently, if this is the situation, there will be specified terminals beneath the hood in situations where a jump start is necessary. Glance at the battery to find the positive and negative terminals. Each terminal ought to be plainly labeled with a + (plus) sign for positive and a – (minus) sign for negative. It is crucial to understand which one is which, as it is essential to guarantee the batteries are linked correctly to perform a fruitful jump start and prevent a hazardous mishap.

Using the Jumper Cables

Here is how to utilize jumper cables if you are jump starting your vehicle with the help of an additional vehicle: The safest order to attach the jumper cables is as follows:

  • Attach one red jumper cable clamp to the positive terminal on the dead battery.
  • Next, attach the other end of the same cable, the second red jumper cable clamp, to the positive terminal on the working (live) car battery.
  • Then, attach one black jumper cable clamp to the negative terminal of the working (live) car’s battery.
  • Attach the other end of that cable, the second black jumper cable clamp, to an unpainted piece of stationary metal on the car with the dead battery. Do not attach this clamp to the negative terminal on the dead car’s battery.

Though some may say it is alright to attach the last negative jumper cable clamp to the negative terminal of the dead battery, this heightens the probability of fire or blast if the jump start does not go as intended. Try to find someplace away from the battery, to reduce the possibility of sparks burning any hydrogen vapor that might be coming from the battery. Safer alternatives include the vehicle’s chassis, a screw on the engine or the alternator brace.

Then, start the vehicle with the good battery. This will instantaneously start charging the dead battery. In some instances, the car with the dead battery will be capable to be started instantly, but in others it will require some period to charge.

Charging the Battery

Permit the engine to operate for a few minutes to let electrical flow to flow from the good battery to the dead one. Then, try to start the car with the dead battery. Rotate the key to start and hold for a few moments. If your jump start was effective, the engine will engage.

Once the Car is Running

The last phase is to unhook the cables. Therefore, it is safest to do this in the subsequent order:

  • Disconnect the negative (black) jumper cable clamp from the chassis/terminal on the car that received the jump start
  • Next, disconnect the negative (black) jumper cable clamp from the working battery’s negative terminal
  • Then, disconnect the positive (red) jumper cable clamp from the working battery’s positive terminal
  • Disconnect the positive (red) jumper cable clamp from the car that received the jump start

Cheers! You have jump started your vehicle!
