Choosing the Right Battery for Your Subaru Outback

To ensure that you choose the right battery for your 2020 Subaru Outback, you need to consider several key factors. Let’s delve into these factors in detail:

Battery Type

The type of battery you choose for your Subaru Outback can have a significant impact on its performance and lifespan. The two main battery types for vehicles are lead-acid batteries and AGM (Absorbent Glass Mat) batteries. Lead-acid batteries are the traditional choice and are known for their affordable price. On the other hand, AGM batteries offer several advantages, such as longer lifespan, better performance in extreme temperatures, and resistance to vibration.

Battery Size

It is crucial to choose a battery that is the correct size for your Subaru Outback. Battery sizes are measured in Group Sizes, and consulting your vehicle’s owner manual or contacting a professional is recommended to determine the appropriate Group Size for your specific model. Choosing the right-sized battery ensures a proper fit and prevents any potential issues with installation or performance.

Cold Cranking Amps

Cold Cranking Amps (CCA) is a measure of a battery’s ability to start your vehicle in cold weather conditions. It represents the amount of current the battery can deliver at 0 degrees Fahrenheit for 30 seconds without dropping below a specified voltage. It is advisable to choose a battery with a higher CCA rating, especially if you live in an area with extremely cold winters.

Reserve Capacity

The reserve capacity of a battery indicates how long it can provide a steady electrical current in case of an alternator failure or any other electrical issues. A battery with a higher reserve capacity ensures that your vehicle’s essential components continue to operate even if there is a problem with the charging system. Consider opting for a battery with a higher reserve capacity to provide an extra safety margin.

Maintenance Free vs. Maintenance Required

When choosing a replacement battery for your Subaru Outback, you will come across two main types: maintenance-free batteries and maintenance-required batteries. Maintenance-free batteries are sealed and do not require any fluid checks or top-ups. On the other hand, maintenance-required batteries require periodic inspection and fluid maintenance. Consider your preferences and convenience when deciding between the two types.


A battery’s warranty is an essential factor to consider when choosing a replacement for your Subaru Outback. A longer warranty period indicates the manufacturer’s confidence in the battery’s quality and lifespan. Look for batteries that offer a substantial warranty, as it provides peace of mind and protection against any potential defects or premature failure.
