A large number of devices on your car require power in order to function. Changing the car battery and cutting off power completely might cause some trouble. You might lose the settings of your radio station, you might have to reset your clock, and you might even have to reset the remote lock system.

Some sound systems might even ask you for a password in order to start working again once they were cut off. In order to avoid such problems, you need to find a solution to power these devices while you replace the battery. A portable jump starter can provide enough power in order to keep the devices going.

Here is what to do:

  • Stop the car and take the keys out of the ignition.
  • Make sure the power switch of the jump starter is on OFF.
  • Take the red cable of the jump starter and connect it to the positive close of the battery. Make sure it will not stand in your way when you will want to disconnect the positive clamp from the battery’s terminal.
  • Take the black clamp; connect it to the chassis or to any other solid, and fix metal component.
  •  Turn on the jump starter.
  • Use a wrench to disconnect the positive clamp on the terminal of the battery. Take the clamp off and put it somewhere safe. This means that it should not be on any grounded metal components. You can also use a cloth to insulate it.
  • Repeat the procedure for the negative clamp.
  • Take the battery out by simply lifting it from its place.
  • Put the new battery in the place of the old one.
  • The positive clamp needs to be repositioned on the positive slot of the latest battery. Use the wrench to secure it in place.
  • Do the same thing for the negative clamp that needs to be repositioned on the negative terminal of the new battery.
  • Turn off the jump starter.
  • Remove the clamps of the jump starter from the clamps and terminals of the battery.
