There are several signs that it could be time to replace your car battery. If your engine takes several attempts to start, or you hear a clicking noise when turning the ignition to start, you may need to learn how to disconnect and install a car battery. It may feel daunting, but the process is straightforward, and many Santa Rosa drivers can do it themselves! Here, we provide everything you need to know on how to disconnect and install a car battery, and you can get a new battery at the dealership or order one online.

The Disconnect and Install a Car Battery Process

A dead battery can significantly hamper your Larkfield-Wikiup drives. The last you need is to be in a hurry to get to work in the morning and find that your car won’t start! Follow these instructions, and you’ll be heading for Petaluma streets with a new battery in your vehicle in no time.

How to Remove the Old Battery

  • Put your Chevy in park and ensure the parking brake is set and that the ignition is turned off.
  • Open your hood and locate your car battery. If you can’t find it, look near the front of the engine compartment along the sides.
  • Detach the negative (-) cable from the battery. Be sure not to allow the wrench to touch the negative and positive terminals simultaneously – this is very important as it could shock you!
  • After removing the negative cable, detach the positive (+) cable from the car battery.
  • Remove the bracket surrounding your battery (if there is one). Then, remove the battery.
  • Be sure to recycle the battery or take it to an authorized retailer for a refund. Do not throw it in the trash!

How to Install the New Battery

  • Check for any visible corrosion on the battery connectors for the positive and negative cables. If you see any, use a wire brush and clean them off.
  • Put the new battery and bracket back in place.
  • Re-connect the positive (+) cable first.
  • Re-connect the negative (-) cable second. Be careful only to connect the cables in this order, so you don’t get an accidental electric shock.
  • Turn on your engine to test the new battery.
