How to jump start a car

Most of the time, cars start right up when you turn the ignition or hit the push-to-start button. Sometimes, the car may not start due to the battery being drained. If that is the case then you’ll need to jumpstart your car. This can be done with either a second car, and a pair of jumper cables or with a portable jump starter. Here is a detailed guide on how to jump-start a car using both methods.

Then connect the black negative clamp to the working battery and the other negative clamp to a piece of unpainted metal under the hood.
