How to Remove a Car Battery

Auto Mechanic Replacing Car Battery

Your car battery is an essential part of your vehicle, but it doesn’t last forever. Whether checking your battery for signs of damage or picking up a replacement battery from our parts department, learning how to remove a car battery safely can save you a trip to the dealership – but it’s important to do it properly. Find out the right techniques for removing a car battery with Cornerstone Chevrolet, serving the Rogers and Elk River area.


Getting Prepared

Batteries can give you a powerful shock, so before you do anything, grab a pair of insulated work gloves and a set of safety goggles. Not only will this protect you from electrical shock, but also any corrosive agents that might be present. Also, be sure to turn off your car to prevent any sparks from igniting. Here are a few other tips:

  • Zip ties and other restraints will help to keep battery cables in place. You’ll want to keep them from touching to prevent sparks and even fire.
  • Take off necklaces, bracelets, watches, and other jewelry. These materials can conduct electricity.
  • Park the car in a well-ventilated area to prevent breathing in harmful fumes.

Removal Process

Removing a car battery can be a little bit tricky, especially if you’re popping the hood for the first time. We recommend keeping your owner’s manual nearby. This booklet offers information specific to your vehicle, along with plenty of diagrams to help you find each component easily.

  • Locate the negative terminal. Look for a black plastic cover or a minus sign on the post.
  • Hold the bolt head of the negative terminal still with a wrench or pliers.
  • Use the other pliers or wrench to remove the nut, and pull off the negative cable. Place it aside, away from the battery.
  • Repeat with the positive cable and be sure that you don’t let the two cables touch.
  • If the battery has a securing bracket, use your pliers or wrench to release the screws and bolts.
  • Lift the battery straight out of the bracket, but be careful. Some batteries weigh up to 40 pounds.

If you’d prefer to let our service department take care of the process for you, simply schedule your service online. We’d be happy to take care of everything from battery replacement to a full inspection at your convenience.
