How to Change a Car Battery the Right Way

West Covina drivers stuck on the side of a Corona road with a dead battery need to know how to disconnect and install a car battery. Follow the steps below and you’ll be back on the road in no time.

Disconnecting Your Old Battery

  • Make sure your vehicle is in park and the ignition is shut off. Then, set the parking brake.
  • Open your hood and locate the battery towards the front of the engine along either side.
  • First remove the negative (-) cable. Do not let the wrench connect the positive and negative terminals at once.
  • After removal of the negative cable (-), you are now free to disconnect the positive one (+).
  • Sometimes there is a compartment holding the battery. You need to remove it too.
  • Now you can detach the old battery. It must be recycled. Don’t toss it in the trash. Return it as an exchange for the new one for a refund.

Attaching the New Battery

  • There may be corrosion on the connectors. Easily scrub them with a wire brush.
  • Install the battery and replace the compartment..
  • Plug in the positive (+) cable first.
  • The negative (-) cable goes next. It is necessary to install these cables in the correct order to protect yourself from a short or electrical shock.
  • Run the engine to see if it works.
