Is your 2015 GMC Terrain having trouble starting? It could be time to replace the battery. In this article, we will guide you through the process of replacing the battery in your GMC Terrain, providing you with the necessary steps and tips to make the task easier.

Step 1: Safety First

Before you start replacing the battery, it is important to ensure your safety. Make sure the ignition is turned off and the key is removed from the vehicle. Additionally, wear protective gloves and goggles to protect yourself from any potential harm.

Step 2: Locate the Battery

The battery in the 2015 GMC Terrain is located in the engine compartment. Open the hood of your vehicle and locate the battery. It is usually positioned near the front of the engine bay.

Step 3: Disconnect the Negative Terminal

Using a wrench or socket, loosen the nut on the negative terminal of the battery. Once loose, remove the negative cable from the terminal and set it aside. This will prevent any electrical current from flowing through the system while you work.

Step 4: Disconnect the Positive Terminal

Repeat the same process for the positive terminal of the battery. Loosen the nut, remove the cable, and set it aside. By disconnecting both terminals, you ensure that there are no electrical connections to the battery.

Step 5: Remove the Battery

After disconnecting the terminals, locate the battery hold-down bracket. It is usually secured by a bolt or clamp. Unscrew or unclip the bracket and remove it. Once the bracket is removed, carefully lift the battery out of the engine compartment.

Step 6: Clean the Battery Tray

While the battery is removed, take the opportunity to clean the battery tray. Use a mixture of baking soda and water to remove any corrosion or residue that may have accumulated over time. This will help ensure a clean and secure connection for the new battery.

Step 7: Install the New Battery

Take the new battery and carefully place it in the battery tray. Make sure it is aligned properly and sits securely. Reinstall the battery hold-down bracket to secure the battery in place.

Step 8: Reconnect the Positive Terminal

With the new battery in place, it’s time to reconnect the terminals. Start with the positive terminal. Slide the positive cable onto the terminal and tighten the nut with a wrench or socket. Make sure it is securely fastened.

Step 9: Reconnect the Negative Terminal

Repeat the same process for the negative terminal. Slide the negative cable onto the terminal and tighten the nut. Ensure that both terminals are securely attached to the battery.

Step 10: Test the Battery

Now that the new battery is installed and the terminals are connected, turn on the ignition to test if the vehicle starts properly. If everything is working correctly, you have successfully replaced the battery in your 2015 GMC Terrain.


Replacing the battery in your 2015 GMC Terrain is a relatively simple task that can be done at home with basic tools. By following these steps, you can save money on labor costs and ensure your vehicle starts smoothly. Remember to always prioritize safety and consult your vehicle’s manual for specific instructions.
