AVILOO’s used-EV battery study points to stronger-than-expected battery health
AVILOO’s 500,000-test study suggests used EV batteries are generally ageing better than expected, including in vehicles tested for Australian relevance.

Verified event
AVILOO has released its Certified EV Battery Report, a study built from more than 500,000 used-EV battery tests collected between 2022 and 2026. The results have been summarised by The Driven and other outlets, with coverage noting that the dataset includes Australian vehicles and is therefore relevant to local used-EV shopping and fleet conversations. 1111215
The headline finding is that battery health is holding up better than many buyers assume. Across 20 popular models, median state of health after 150,000 km is typically reported in the high 80s to mid-90s, with several models such as the Hyundai Ioniq 5, Tesla Model Y and Mercedes-Benz EQA appearing near the top of the table. 13891115
What the data shows
The same study also shows that averages do not tell the full story. AVILOO says state of health can vary by as much as 13.5 percentage points between individual cars of the same model, which points to charging habits, usage patterns and other variables having a material effect on degradation. 671112
That matters for Australian readers because the study is not being presented as a niche overseas anomaly. The reporting explicitly connects the data to Australian testing and to models that are already familiar in the local market, although local price, availability and market impact have not been confirmed. 1111415
Our take
Our take: In our view, the significance of this report is less about a single best-performing model and more about what it does to the used-EV risk conversation. If batteries in common models are generally retaining around 90% of usable capacity at 150,000 km, then the old assumption that used EVs are automatically compromised looks harder to defend. 161115
One possible implication is that battery health testing may become more important than odometer reading alone when comparing used EVs. In our view, the 13.5-point spread within the same model suggests buyers and sellers cannot rely on model averages to describe a specific car, which makes measured state of health a more useful reference point than broad generalisations. 6711
