Understanding Battery Health: What Scan Tools Don’t Show

Understanding Battery Health

Across the Gold Coast and Tweed Heads, we’re seeing more hybrids and EVs come in for assessments — not just repairs. As these vehicles age, one question keeps coming up: What’s the real health of the battery?

What SOH Really Means

SOH, or State of Health, is often shown as a percentage on scan tools. But that number alone doesn’t tell the full story. It doesn’t show how the battery has aged, whether it’s been reset, or how driving habits have shaped its performance.

That’s why scan data needs context — and technician insight.

What We Look For

At NextPhase Auto, we go beyond the numbers. Our assessments include:

  • Battery history flags (e.g., swaps, resets, firmware updates)

  • Thermal variance checks across modules

  • Scan tool overlays to catch hidden faults

  • Disclaimers when data is provisional or incomplete

This helps build diagnostic confidence — not just for technicians, but for buyers, sellers, and insurers.

Why It Matters

As insurers begin factoring battery health into coverage decisions, and as resale platforms seek reliable grading systems, having a technician-verified SOH report can protect both buyers and sellers.

It’s not just about today’s fault codes — it’s about tomorrow’s value.

Our Approach

We’re not trying to be flashy. We’re trying to be accurate. And in a changing automotive landscape, accuracy builds trust.
