How to Choose the Right Battery Amps for Your Subaru: The Ultimate Guide to Extending Battery Longevity and Vehicle Performance

If you’re a proud owner of a Subaru, you know that this vehicle is made for outdoor adventures and rough terrains. To ensure that your Subaru performs its best during every ride, it’s essential to have a reliable battery that can supply the necessary electrical power. However, choosing the right battery amps for your Subaru can be confusing, especially if you’re not familiar with the specific requirements of your vehicle. In this article, we’ll provide you with all the essential information you need to choose the right battery amps for your Subaru and extend its battery longevity.

Understanding Battery Amps for Your Subaru

The amperage in a car battery measures the rate of electrical current flow that the battery can generate. It signifies the amount of power that the battery can provide to the electrical system of your vehicle. The higher the battery amps, the more powerful your car battery is, and the better it can perform. However, choosing a battery with too many amps than needed can lead to a short battery lifespan or may even damage your car’s electrical components.

Subaru vehicles require a specific range of battery amps suitable for their power and performance requirements. Generally, most Subaru cars require batteries with a capacity range of 300-700 CCA (Cold Cranking Amps) that can deliver sufficient power to start the engine and supply energy to other electrical components in your car.

Different Types of Batteries

Now that you understand the significance of battery amps let’s delve deeper into the types of batteries available for your Subaru.

  1. Lead-acid batteries: These are the standard batteries found in most cars. They are cost-effective, reliable, and have a high CCA range. However, they require frequent maintenance and have a short lifespan.

  2. AGM (Absorbent Glass Mat) batteries: These batteries are more advanced and have a longer lifespan than lead-acid batteries. They are maintenance-free, can withstand extreme temperatures, and have a higher CCA range. However, they are more expensive than lead-acid batteries.

  3. Lithium-ion batteries: These are lightweight, long-lasting, and more eco-friendly batteries that have gained popularity in recent years. Lithium-ion batteries have a higher CCA range and are suitable for vehicles that demand high electrical power. However, they are costly compared to traditional batteries.

Tips for Battery Maintenance

To ensure optimal performance and extend the lifespan of your Subaru’s battery, regular maintenance is crucial. Here are some tips to keep your battery performing at its best:

  • Keep the battery terminals clean and free from corrosion.

  • Check the battery water level frequently and refill it when necessary.

  • Avoid using electrical components when your car is turned off.

  • Ensure that all lights and electrical components are turned off when you park your car.

  • Use a battery charger to maintain the battery’s charge level during extended trips.


Q: What is the recommended CCA range for a Subaru battery?

A: Most Subaru vehicles require a battery with a CCA range between 300-700.

Q: How often should I replace my car battery?

A: The average lifespan of a car battery is around 3-5 years. However, frequent battery usage and extreme weather conditions can cause the battery to wear out sooner.
