Replacing your Subaru Crosstrek Battery might seem straightforward, but for models equipped with the start-stop system, it’s crucial to choose the right type. This guide explores a user’s experience and key considerations when selecting a replacement battery for your Subaru Crosstrek, ensuring compatibility and optimal performance.
Understanding Start-Stop Battery Requirements
Subaru, like many modern vehicles, utilizes start-stop technology to improve fuel efficiency. This system places higher demands on the battery, requiring it to withstand frequent cycles of charging and discharging. Standard lead-acid batteries are often insufficient for these demands, leading to premature failure and potential system issues. Absorbent Glass Mat (AGM) batteries are specifically designed for start-stop systems due to their enhanced durability and performance under these conditions.
Aftermarket Battery Options for Subaru Crosstrek
When considering a replacement, you might wonder about using aftermarket batteries instead of solely relying on Subaru-branded parts. One Subaru owner inquired with their local parts department about aftermarket options. While initially directed towards certified Subaru parts, further inquiry revealed that aftermarket batteries are indeed viable, provided they are compatible with the start-stop system.
This owner successfully installed a DieHard Platinum AGM Battery in their 2021 Crosstrek Sport. This experience highlights that you are not limited to OEM batteries and can explore reputable aftermarket brands for your Subaru Crosstrek battery replacement.
DieHard Platinum AGM Battery: A User Experience
The user reported a seamless DIY battery replacement process with the DieHard Platinum AGM (Group Size 35). Key specifications of this battery include:
- Group Size: 35
- Cold Cranking Amps (CCA): 650
- Cranking Amps (CA): 810
- Reserve Capacity: 100 Minutes
Crucially, the battery swap was straightforward, requiring only a 10mm deep socket for the bolts. No computer reprogramming or battery registration was necessary for this Subaru Crosstrek model, simplifying the replacement process significantly.
Choosing the Right Battery: Key Specs to Consider
When selecting a Subaru Crosstrek battery, especially for start-stop systems, prioritize AGM batteries and consider these specifications:
- Group Size: Ensure it matches the original battery size (Group 35 is common).
- CCA/CA: Cold Cranking Amps and Cranking Amps indicate the battery’s starting power. Higher values are generally better, especially in colder climates.
- Reserve Capacity: This indicates how long the battery can power essential accessories if the alternator fails. A higher reserve capacity offers more extended backup power.
