How Much Does It Cost to Replace a Subaru Battery? Your Ultimate Guide to Battery Replacement

Are you a Subaru owner who needs to replace your car battery? If so, you may be wondering how much it’s going to cost. The good news is that replacing a Subaru battery is generally less expensive than other popular car brands. In this article, we will be discussing everything related to Subaru battery replacement, including how much it should cost, the types of batteries available, how to test for a bad battery, and how to properly dispose of an old battery.

Why Does a Subaru Battery Need to Be Replaced?

Before we dive into the costs of replacing a Subaru battery, it’s essential to understand why a battery typically needs to be replaced. Most car batteries last between three to five years, with some lasting longer depending on usage and maintenance. However, extreme weather conditions, frequent short trips, and leaving the radio or lights on when the car is off can all reduce a battery’s lifespan.

How Much Should a Subaru Battery Replacement Cost?

The cost of a Subaru battery replacement can vary depending on several factors, including the year and model of the vehicle and the type of battery needed. On average, Subaru battery replacement costs range from $150 to $375, with the battery itself accounting for around $80 to $200 of that price. However, some dealerships or service centers may charge more, so it’s essential to shop around and compare prices.

Types of Batteries Available for Subaru Vehicles

When replacing your Subaru battery, you’ll have several options to choose from. The most common types of batteries for Subaru vehicles are lead-acid batteries, which are reliable and relatively inexpensive. However, other battery types, such as AGM (Absorbent Glass Mat) or lithium-ion batteries, may be necessary for newer Subaru models or for owners who frequently use electronic or audio accessories.

How to Test for a Bad Battery

If your Subaru battery is showing signs of weakness, such as a slow start-up or difficulty holding a charge, it may be time to replace it. However, before replacing the battery, it’s essential to confirm that it is, indeed, the problem. A quick way to test a bad battery is to use a voltmeter or multimeter to measure the voltage across the battery terminals. A reading of less than 12.4 volts indicates a weak or bad battery.

Proper Battery Disposal

Once you’ve replaced your Subaru’s battery with a new one, you’ll need to dispose of the old battery correctly. The lead-acid batteries commonly used in cars are hazardous and should not be thrown away in the trash. Instead, take the old battery to a designated recycling center or to an auto parts store that offers battery disposal services.


Q: Can I replace the Subaru battery myself?

A: If you have experience working on cars and the proper tools, you can typically replace the battery yourself. However, if you’re unsure or uncomfortable performing the task, it’s best to leave it to a professional.
