Subaru Ascent Battery Replacement

Replacing the battery in your Subaru Ascent is a simple and straightforward process. Whether your battery has reached the end of its lifespan or you simply want to upgrade to a more powerful option, this guide will provide you with all the information you need to successfully replace your Subaru Ascent battery.

Why Replace Your Subaru Ascent Battery?

There are a few reasons why you might need to replace the battery in your Subaru Ascent:

• Age: Like all batteries, the battery in your vehicle will eventually wear out and lose its ability to hold a charge. If your battery is older than three years, it’s a good idea to consider replacing it.
• Performance: If you’re experiencing issues starting your car or notice dimming headlights or electronics, it could be an indication that your battery is no longer performing optimally.
• Upgrades: Some Subaru Ascent owners choose to upgrade their battery to a more powerful option to accommodate additional accessories or enhance performance.

Choosing the Right Battery

Before replacing your Subaru Ascent battery, it’s essential to choose the right one that fits your vehicle’s specifications. Here’s what you need to consider:

Battery Type

There are two main types of batteries to choose from:

• Lead-Acid Batteries: These batteries are the most common and often the least expensive option. They are reliable and can provide ample power for most vehicles.
• AGM (Absorbent Glass Mat) Batteries: AGM batteries are a more advanced and durable option. They are spill-proof, maintenance-free, and are known for providing exceptional performance in extreme conditions.

Check your owner’s manual or consult with a professional to determine which type of battery is recommended for your Subaru Ascent.

Battery Size

Make sure to choose a battery with the correct size and terminal placement to ensure a proper fit in your Subaru Ascent’s battery compartment. The battery’s group size can typically be found in the owner’s manual or on the old battery itself.

Cold Cranking Amps (CCA)

The Cold Cranking Amps (CCA) rating indicates the battery’s ability to start your vehicle in cold weather conditions. It represents the amount of current the battery can deliver for 30 seconds at 0°F while maintaining a voltage of at least 7.2 volts. Ensure that the replacement battery has a CCA rating equal to or greater than the original battery.

Reserve Capacity (RC)

Reserve Capacity (RC) is the number of minutes a fully charged battery can sustain a load of 25 amps before dropping below 10.5 volts. A higher RC rating indicates a longer-lasting battery in case of alternator failure. Consider choosing a battery with a higher RC rating for added peace of mind.

Steps to Replace the Battery

Once you’ve obtained the correct replacement battery, follow these steps to replace the battery in your Subaru Ascent:

Step 1: Safety Precautions

1. Park your Subaru Ascent on a level surface and engage the parking brake.
2. Turn off the ignition and remove the key.
3. Open the hood and secure it using the prop rod or hood support.

Step 2: Locate the Battery

The battery is typically located in the engine compartment, either on the driver’s side or passenger’s side. Consult your owner’s manual if you’re having trouble finding it.

Step 3: Disconnect Negative Terminal

1. Using a wrench or pliers, loosen and remove the negative terminal (marked with a minus sign) from the battery. It’s recommended to start with the negative terminal to minimize the risk of electrical shock.
2. Wrap the disconnected negative terminal with a clean cloth or tape to prevent accidental contact.

Step 4: Disconnect Positive Terminal

1. Similarly, loosen and remove the positive terminal (marked with a plus sign) from the battery.
2. Secure the disconnected positive terminal away from the negative terminal to avoid any contact.

Step 5: Remove Battery Hold-Down Bracket

1. Some Subaru Ascent models may have a battery hold-down bracket or strap. If present, remove it using the appropriate tool, such as a wrench or socket set.

Step 6: Take Out the Old Battery

1. Carefully lift the old battery out of the battery tray and set it aside.

Step 7: Clean the Battery Tray

1. Inspect the battery tray for any dirt, debris, or corrosion. Use a battery cleaner or a mixture of baking soda and water to clean the tray if necessary.
2. Dry the tray thoroughly before proceeding.

Step 8: Install the New Battery

1. Place the new battery into the battery tray, ensuring it sits securely and properly aligned.

Step 9: Reinstall Battery Hold-Down Bracket

1. If your Subaru Ascent has a battery hold-down bracket or strap, reattach it to secure the new battery in place.

Step 10: Reconnect Positive Terminal

1. Attach the positive terminal to the corresponding post on the new battery and tighten it securely.

Step 11: Reconnect Negative Terminal

1. Attach the negative terminal to the corresponding post on the new battery and tighten it securely.

Step 12: Double-Check Connections

Ensure that both the positive and negative terminals are tightly connected to the battery.

Step 13: Close the Hood

Gently lower the hood and ensure it is fully closed before starting your Subaru Ascent.

Maintaining Your Subaru Ascent Battery

Proper maintenance can help extend the lifespan of your Subaru Ascent battery and ensure optimal performance. Here are a few tips:

• Regular Inspections: Check the battery terminals for corrosion or loose connections. Clean the terminals if necessary and tighten any loose connections.
• Keep it Clean: Periodically clean the battery case and terminals using a solution of baking soda and water to remove dirt and corrosion.
• Drive Regularly: Frequent driving allows the battery to charge fully. If your vehicle sits idle for extended periods, consider using a battery tender or trickle charger to maintain the charge.
• Extreme Temperatures: Extreme temperatures can impact battery performance. If you live in an area with harsh winters, consider installing a battery insulation kit to protect your battery from freezing.

By following these maintenance practices, you can help ensure your Subaru Ascent battery lasts as long as possible.
