How to jump start a dead battery with a jump-starter?

Assuming that the Noco jump starter has been accessed, the remaining process is just a matter of a few minutes. But, there are some precautions that must be taken.

The dead battery should be checked before jump-starting. A check must be done to see if it is damaged or not. Check for any cracks in the body. If the battery is fine physically, then the process can be undertaken. 

Before attempting to jump start a car, the user manual of the car with the dead battery must be read. Could have some advice or crucial information for such instances. 

Steps to take before undertaking the jump start:

  • Everything in the car should be turned off including the lights. 
  • Any smartphone charger must be unplugged.
  • The radio or air conditioner must be turned off. 
  • If there is enough time, then any dirt or deposit on the battery terminals should be cleaned before the procedure. 
  • The driver must put the car in neutral or parking mode to ensure safety. 

After sorting these things out, the Noco jump starter can come into play. 

Attach the red clip to the positive terminal of the dead battery. The black clip should then be clipped to the negative terminal. 

Turn on the power button on the Noco jump starter, and immediately give the car a start. If the car starts, great! If it does not, click on the boost button on the power bank and start the car again. The car should get started this time. 

Once the car finally starts, turn off the jump-starter and disconnected immediately. Leave the car battery to charge for a few minutes while stationary. And if possible, a 10-minute spin can also be taken, to allow the battery to charge.
