How to Remove a Car Battery

car battery

A critical part of your vehicle’s operations, the battery starts the car up, keeps it running, and helps power all the electrical components. In order to keep up those functions, you may need to replace it when the charge runs down or remove it to check it for signs of damage. This is a relatively simple task you can do by yourself, but it can be dangerous if not done properly. Read on to find out how to remove a car battery safely from Dick's Hillsboro Honda’s service department.

Materials & Preparation


You’ll need to start by securing a pair of insulated work gloves, as car batteries hold enough charge to deliver a deadly shock. You should also wear safety goggles to protect your eyes from corrosive agents. Make sure your vehicle is off before starting — running vehicles can produce a spark and ignite flammable agents. You should also make sure to:

  • Get some zip ties or other form of restraint to keep the battery cables in their proper place. Preventing them from touching is important because it’ll create sparks and become a fire hazard.
  • Avoid the risk of metal-to-metal contact by covering the positive cable end with a cloth once it is removed.
  • Take off any jewelry — including necklaces, watches, and bracelets — to prevent getting a shock if they come in contact with the battery.
  • Ensure you’re in a well-ventilated area to prevent exposure to harmful gases.

In the event the terminal is fused, you’ll need a special battery cable removal tool to loosen it. If you need help finding one, we can supply it at our Hillsboro parts departments or you can check general auto parts stores.

Steps to Removing a Car Battery

Once you’ve taken the necessary safeguards, you can begin removing your car battery:

  • Find the negative terminal; it should have a black plastic cover or a minus sign and can be found either on the post or in close proximity.
  • Use a wrench or pliers to grab the bolt head of the negative terminal and hold it still.
  • Take pliers or a wrench and remove the nut, then pull off the negative cable and secure it away from the battery.
  • Repeat the above step for the positive cable, ensuring that the two battery cables don’t touch.
  • If the battery is held by a securing bracket, use the pliers or wrench to remove its screws and bolts.
  • Lift the battery straight out of the bracket. Do so carefully; a battery can weigh around 40 pounds.
