GET DIRECTIONS

Slow cranking, dim headlights, random warning lights, or a Subaru that won't start at the worst possible moment, these are all signs your battery or charging system needs attention. When that happens, you don't just need a new battery thrown in, you need Subaru battery replacement and testing from specialists who understand these cars inside and out.


At East Valley Auto Rebuild in Kent, WA, we handle everything from simple Subaru battery swaps to full electrical diagnostics and repairs. Founded by Mark Bryant, the Independent Subaru Guru, and his wife Denise, our family-owned shop has 30+ years in the automotive industry and 70+ years of combined Subaru experience. We're "Your Sensible Dealership Alternative" for reliable, honest Subaru battery service.

Why Subaru Battery Service Matters

Modern Subarus rely heavily on electronics, multiple control modules, safety systems, infotainment, heated seats, and more. A weak or failing battery can cause:


  • Hard starting or no-start conditions

  • Flickering or dim lights

  • Random warning lights on the dash

  • Intermittent electrical issues that are hard to pin down

  • Strain on the alternator and starter over time

Proper Subaru battery service isn't just about replacing the battery, it's about making sure the entire electrical and charging system is healthy. That's why our technicians test, verify, and explain what's going on before we recommend Subaru car battery replacement.

Complete Subaru Battery Replacement Service in Kent, WA

When you bring your Subaru to East Valley Auto Rebuild for Subaru battery replacement, we follow a thorough, step-by-step process designed for accuracy and peace of mind:

1. Battery Health Testing
  • We test your current battery's voltage, cold cranking amps (CCA), and overall condition.

  • Results are shared and explained so you can see whether the battery is actually failing or simply weak.
2. Charging System & Electrical Check
  • We check alternator output, charging voltage, and basic wiring/connection health.

  • If we suspect a parasitic draw or deeper electrical issue, we'll discuss diagnostic options before replacing parts.
3. Quality Battery Selection
  • We install high-quality batteries with the correct specs and proper cold cranking amps for Pacific Northwest winters.

  • We make sure the battery meets Subaru-specific requirements for your model and year.
4. Installation & Setup
  • Clean and protect battery terminals and connections.

  • Secure the battery properly to avoid vibration-related failures.

  • For newer models that require it, we perform any necessary registration/coding so the vehicle's systems recognize the new battery correctly.
5. Final Verification
  • Re-test system voltage and charging after installation.

  • Confirm that the vehicle starts reliably and that dash behavior is normal.

You leave knowing your Subaru's starting and charging system has been checked, not just the battery swapped.

The quality of work is top notch. Took my 2011 STI there to get the head gaskets done and could not be more pleased with the work they did and how they treated me through the process. Sent photos and videos of the entire process while taking apart the motor. Great people who really do want the best for the customer and their car. Would absolutely take my Subaru there again if needed.

I brought my 2017 wrx with a blown engine to Mark at east valley auto rebuild. I really liked how he took the extra time to discuss all my available options, from keeping it stock to going with more quality parts. Mark covered it all with his extensive knowledge while he tooks us out to lunch. He really made sure that what I wanted out of and from the car is what I got.
