The battery operates at a voltage of 12 volts, delivering a steady flow of electricity to power the vehicle’s electrical systems. Its amperage, measured in ampere-hours (Ah), determines the amount of current it can deliver over time. The Ascent’s battery offers a substantial amperage, ensuring it can handle the electrical demands of the vehicle, even under challenging conditions.

Battery Capacity

The 2025 Subaru Ascent battery has a capacity of 60 kilowatt-hours (kWh), providing ample energy storage to power the vehicle’s electrical systems. This capacity allows for extended use of accessories, such as the audio system, navigation, and climate control, without draining the battery.

Battery Chemistry

The 2025 Subaru Ascent battery utilizes advanced lithium-ion chemistry, known for its high energy density, lightweight construction, and long lifespan. Lithium-ion batteries are commonly found in electric vehicles and provide a reliable and efficient power source for the Ascent’s electrical systems.

Battery Performance

The 2025 Subaru Ascent is estimated to have an electric range of up to 350 miles on a single charge. This range is comparable to other electric SUVs in its class, such as the Tesla Model X and the Audi e-tron.

The Ascent’s battery can be charged using a variety of methods, including Level 1, Level 2, and DC fast charging. Level 1 charging is the slowest method, and it typically takes several hours to fully charge the battery. Level 2 charging is faster, and it can fully charge the battery in a matter of hours. DC fast charging is the fastest method, and it can charge the battery to 80% capacity in as little as 30 minutes.

The Ascent’s battery is expected to have a lifespan of 10 years or 150,000 miles, whichever comes first. The battery is also expected to degrade at a rate of about 2% per year. This means that after 10 years, the battery will still have about 80% of its original capacity.

Battery Maintenance

The 2025 Subaru Ascent battery requires regular maintenance to ensure optimal performance and longevity. This includes checking the battery’s health, cleaning the terminals, and storing it properly when not in use.

Checking the Battery’s Health and Condition

Regularly checking the battery’s health is crucial to prevent unexpected failures. This can be done using a voltmeter or a battery tester. A voltmeter should read around 12.6 volts when the engine is off and 14 volts when the engine is running. A battery tester will provide a more detailed analysis of the battery’s condition, including its capacity and CCA (Cold Cranking Amps) rating.

Battery Terminal Cleaning

Battery terminals can accumulate corrosion over time, which can impede the flow of electricity. To prevent this, it is important to clean the terminals regularly using a wire brush or a battery terminal cleaner. Apply a thin layer of petroleum jelly to the terminals after cleaning to prevent future corrosion.

Battery Storage

When storing the battery, it is important to keep it in a cool, dry place. Avoid exposing the battery to extreme temperatures, as this can damage the battery’s internal components. If the battery will be stored for an extended period of time, it is recommended to disconnect it from the vehicle and charge it every few months to maintain its charge.
