In Subaru models, the battery is usually located under the hood, near the front of the car. It is typically on the driver’s side but may vary depending on the model and year. Check the owner’s manual or search online to find the exact battery location in your Subaru.
Battery Type and Specifications
Subaru cars usually have a standard lead-acid battery, but it’s important to confirm the battery type and specifications for your model. Pay attention to the battery’s group size (physical dimensions) and cold cranking amps (CCA) rating, which determines its ability to start the engine in cold weather.
Gathering the Necessary Tools
Before beginning the battery replacement process, gather the required tools to ensure a smooth and efficient experience. Here’s a list of tools you may need:
- Socket set with various sizes
- Wrench
- Battery terminal cleaner
- Battery terminal grease or petroleum jelly
- Battery brush or wire brush
- Protective gloves and safety glasses
- Battery hold-down bracket (if needed)
Preparing for Battery Replacement:
Proper preparation is key to a successful battery replacement. Take the following steps to ensure a safe and efficient process:
Safety Precautions
It’s essential to prioritize your safety when working with a car battery. Here are a few precautions to keep in mind:
- Ensure the engine is turned off and the ignition key is removed.

- Avoid smoking or open flames in the vicinity of the battery as it can emit flammable gases.
Battery Terminal Cleaning:
Before removing the old battery, it’s crucial to clean the battery terminals to prevent any issues with the new battery’s performance. Follow these steps to clean the terminals:
- Start by disconnecting the negative terminal (usually marked with a minus sign [-]) using an appropriate-sized wrench or socket.
- Once disconnected, use a battery terminal cleaner or a wire brush to remove any corrosion or buildup from the battery posts and terminals.
- Repeat the process for the positive terminal (usually marked with a plus sign [+]).
- After cleaning, apply a thin layer of battery terminal grease or petroleum jelly to the battery terminals to prevent future corrosion.
Removing the Old Battery:
Now that you’re prepared and have cleaned the battery terminals, it’s time to remove the old battery. Follow these steps carefully:
Removing Battery Hold-Down Bracket (if applicable)
In some Subaru models, a battery hold-down bracket keeps the battery securely in place. If your Subaru has one, follow these steps to remove it:
- Locate the battery hold-down bracket and use the appropriate-sized wrench or socket to loosen and remove any bolts or screws securing it.
- Once the bracket is removed, set it aside in a safe place.
Disconnecting the Old Battery
To disconnect the old battery, follow these steps:
- Start by loosening and removing the bolt or nut on the negative terminal using the appropriate-sized wrench or socket.
- Carefully lift the negative terminal off the battery post, ensuring it doesn’t make contact again.
- Repeat the process for the positive terminal.
Removing the Old Battery
With the terminals disconnected, remove the old battery from its position:
- Gently lift the old battery out of its tray, taking care not to spill any battery acid.
- Set the old battery aside in a safe location away from children or pets.
Installing the New Battery:
With the old battery successfully removed, it’s time to install the new battery in your Subaru. Follow these steps to ensure a proper installation:
Checking the New Battery:
Before installing the new battery, double-check its specifications to ensure it matches the old battery’s group size and CCA rating. Additionally, inspect the new battery for any signs of damage or defects.
Placing the New Battery:
Follow these steps to place the new battery in your Subaru:
- Carefully position the new battery in the battery tray, ensuring it is aligned correctly.
- Make sure the positive and negative terminals are easily accessible.
5.3 Connecting the New Battery
To reconnect the new battery, follow these steps:
- Start by attaching and tightening the positive terminal clamp onto the positive battery post using the appropriate-sized wrench or socket.
- Repeat the process for the negative terminal clamp.
- Ensure the terminals are securely connected with no loose connections.
Securing the Battery:
To ensure the new battery remains secure in your Subaru, follow these steps:
Reattaching the Battery Hold-Down Bracket (if applicable)
If your Subaru has a battery hold-down bracket, follow these steps to reattach it:
- Position the battery hold-down bracket over the new battery.
- Use the appropriate-sized wrench or socket to tighten the bolts or screws, securely fastening the bracket in place.
Performing a Final Check
After securing the battery, perform a final check to ensure everything is in place:
- Double-check that all connections are tight and secure.
- Inspect the battery terminals to ensure they are clean and free of corrosion.
- Verify that the battery is properly positioned in the tray and secured by the hold-down bracket.
Testing and Maintenance:
Once the new battery is installed, it’s crucial to test its performance and perform regular maintenance to ensure its longevity. Here are a few essential steps:
Testing Battery Voltage:
Using a multimeter, test the battery voltage to ensure it’s within the appropriate range. This step verifies that the battery is charging properly and capable of powering your Subaru’s electrical systems.
Regular Maintenance:
To maintain the battery’s performance, consider the following maintenance tips:
- Keep the battery terminals clean and free of corrosion.
- Check the battery’s fluid level (if applicable) and top it up if necessary.
- Frequently inspect the battery for any signs of damage or leaks.
