Subaru is a popular brand of vehicles among car enthusiasts and everyday drivers alike. Known for their reliability, safety, and performance, Subaru cars and SUVs are a common sight on the road. But when it comes to the battery that powers these vehicles, many drivers may wonder: are Subaru batteries good?

In this article, we’ll take a closer look at Subaru batteries and their quality, durability, and performance. We’ll also discuss the different types of batteries available for Subaru vehicles and offer some tips for maintaining and optimizing your Subaru battery.

Types of Subaru Batteries

Subaru offers a variety of battery options for their vehicles, including traditional lead-acid batteries and advanced AGM (Absorbent Glass Mat) batteries. Lead-acid batteries are the most common type of car battery and have been used for decades. These batteries contain a mixture of water and sulfuric acid and rely on a chemical reaction to produce electrical power.

AGM batteries, on the other hand, use a different technology that enhances their durability and performance. Instead of a liquid mixture, these batteries use a thin fiberglass mat to hold the acid in place. This design allows for better conductivity, faster charging times, and greater resistance to vibration and shock. AGM batteries are also less likely to leak or spill, making them a safer option for many drivers.

Subaru offers both types of batteries for their vehicles, depending on the model and year. Most newer Subaru models come equipped with AGM batteries, while older models may still use lead-acid batteries. If you’re unsure which type of battery your Subaru vehicle needs, consult your owner’s manual or a trusted mechanic.

Quality and Durability

One of the main factors that determine the quality of a car battery is its construction. Subaru batteries are known for their high-quality construction, which includes features like corrosion-resistant terminals, reinforced handles, and sturdy casings. These elements help to protect the battery from damage and extend its lifespan.

Another factor that affects battery quality is its brand and origin. Subaru OEM (Original Equipment Manufacturer) batteries are manufactured by reputable brands and designed specifically for Subaru vehicles. These batteries are rigorously tested and meet or exceed industry standards for performance and durability.

If you’re looking for a replacement battery for your Subaru vehicle, it’s important to choose a reputable brand with a proven track record of quality and reliability. Some of the top aftermarket battery brands for Subaru vehicles include Optima, Interstate, and Bosch.

Maintenance and Care

To ensure optimal performance and longevity for your Subaru battery, it’s important to practice regular maintenance and care. Here are some tips for keeping your battery in top shape:

  • Keep the battery terminals clean and free of corrosion. Use a wire brush or battery cleaning tool to remove any buildup or debris.
  • Check the battery voltage regularly with a multimeter or voltmeter. A healthy battery should have a voltage of around 12.6 volts.
  • Avoid leaving your vehicle in extreme temperatures for extended periods of time. High heat can cause the battery to degrade more quickly, while extreme cold can reduce its efficiency.
  • Turn off all lights and accessories when you turn off your vehicle. This can help reduce the strain on the battery and prevent it from draining too quickly.
