What You’ll Need

Before you begin, make sure you have the following tools:

Step-by-Step Guide

Step 1: Preparing to Replace the Battery

The first step is to prepare your Outback for the battery replacement. Turn off the engine and remove the key from the ignition. Open the hood of your Outback and locate the battery, which is typically situated on the driver’s side of the engine compartment. Remove the battery’s negative terminal to prevent electrical shock while you work.

Step 2: Removing the Old Battery

Use your wrench or pliers to remove the battery terminals from the battery. Always loosen the nut on the negative (-) terminal first. Once you’ve removed the terminals, gently lift the old battery out of its tray, ensuring you don’t make physical contact with the terminals.

Step 3: Preparing the New Battery

Before installing the new battery, check its voltage and size. It is essential to choose the right battery that matches the car’s specification and the Outback’s requirements. Clean the battery terminals and replace the battery’s hold-down clamp on the tray to prevent the battery from moving while you drive.

Step 4: Installing and Connecting the New Battery

Carefully place the new battery into the tray, ensuring the positive (+) terminal is at the same end as before. It’s critical to ensure that the battery is correctly placed in the tray’s correct position. Then, re-connect the positive terminal first, followed by the negative terminal. Make sure the terminals are securely fastened and won’t come loose while you’re driving.

Step 5: Testing the New Battery

Now that you’ve installed the new battery, it’s time to test it. Turn on the ignition key, and if the car starts up without any problem, the installation was successful. If the car doesn’t start up, double-check the battery terminal connections and ensure your battery matches the correct voltage and size required by the car.
