Is the Subaru battery AGM or standard?
The majority of Subaru vehicles ship with a conventional flooded 12-volt lead-acid battery rather than an AGM battery. AGM is not the default across most models, though some trims, markets, or configurations may use AGM or VRLA-type batteries. Always verify for your exact model and year.
Understanding the type of 12-volt battery in your Subaru matters for maintenance, replacement cost, and compatibility with electrical upgrades. This article outlines the typical configurations and how you can confirm the correct battery type for your vehicle.
What type of 12V battery does Subaru use?
Subaru generally equips its vehicles with a standard flooded lead-acid 12-volt battery, which is the most common and cost-effective option for everyday use. AGM batteries are not the norm for most Subaru models. However, depending on the model, trim level, market, or specific electrical demands, AGM or VRLA-type batteries may be used in some cases.
Common configurations by model and market
- Most Subaru models sold in North America use a conventional flooded 12V battery as the standard option.
- AGM/VRLA batteries are not the default; they may appear only on certain trims or regional specifications with higher electrical loads or particular features.
- Hybrid, plug-in hybrid, or markets with unique configurations might specify an AGM or VRLA-type 12V battery in place of a flooded unit.
- Battery type is model/year-specific—the exact specification is listed in the owner's manual or the official parts catalog.
In practice, unless your Subaru explicitly lists an AGM/VRLA battery for your exact model and year, you should expect a standard flooded 12V battery to be the factory-installed option.
How to confirm the battery type in your Subaru
To be certain of the battery type for your vehicle, use the following verification steps.
- Inspect the battery label itself. Look for markings such as "AGM," "VRLA," or "FLOODED" on the top or side of the battery.
- Consult the owner's manual or official Subaru service information for your model/year, which will specify the correct battery type.
- Provide your Vehicle Identification Number (VIN) to a Subaru dealer or official parts department to retrieve the exact battery specification for your car.
- When in doubt after checking labels and manuals, rely on the dealer’s guidance or a trusted automotive technician to ensure you use the correct replacement type.
By confirming through these steps, you can avoid installing an incompatible battery and ensure optimal performance for your Subaru’s electrical systems.
Subaru maintenance considerations
Regardless of type, proper maintenance—keeping terminals clean, ensuring a secure connection, and testing the 12V battery health—helps prevent unexpected starting issues. If you upgrade to higher electrical demand components or install aftermarket accessories, you may revisit whether an AGM battery is more suitable, but only if your model supports it or your dealer recommends it.
Summary
In most Subaru models, the factory 12V battery is a standard flooded lead-acid unit. AGM batteries are not the default across the lineup, though some markets or specific trims may use AGM or VRLA configurations. To be certain, check the battery label, refer to the owner's manual or Subaru’s official parts catalog, and confirm with a dealer using your vehicle’s VIN. This ensures you replace the battery with the correct type and maintain reliable vehicle operation.
