Everything you need to know about EV battery health

A vehicle history report tells you about past accidents and mileage, but for electric and plug-in hybrid vehicles, battery condition is critical. At VitalVIN, we bring total transparency and confidence to used EV buying and selling through independent AVILOO diagnostics.

Frequently asked questions

Find clear answers about our rapid testing process, State of Health (SoH) diagnostics, and how independent verification protects your investment.

How healthy is the battery?

The independent AVILOO Battery Certificate verifies the battery's true State of Health (SoH). It provides an objective, data-backed measurement of overall battery condition derived straight from live vehicle data rather than proprietary estimates.

Can the test detect hidden battery problems?

Yes. AVILOO diagnostics inspect battery management system functionality, sensor accuracy, communication stability, and internal cell behavior down to the individual cell level to uncover abnormalities invisible in a regular inspection.

Why can't I just trust the dashboard battery percentage?

Different automakers calculate and display battery information using varying proprietary algorithms, making cross-brand comparison misleading. VitalVIN provides a standardized, independent battery evaluation across supported EV and PHEV models for reliable comparison.

How does the battery compare to similar vehicles?

Each report includes benchmark performance comparisons against comparable makes, models, and mileage cohorts, allowing you to instantly see whether the battery ranks below average, average, or above average for its class.

How long does the testing process take?

The AVILOO FLASH Test connects directly to your vehicle's diagnostic port and completes in approximately 3 minutes. No road test or driving is required.

What kind of report will I receive?

You will receive a printed battery certificate alongside comprehensive test metrics. Every report includes a secure QR code for convenient digital access and sharing at any time.

What real-world driving range can I realistically expect?

Our comprehensive report includes detailed range-related insights and comparisons with similar vehicles, giving you a clear, honest picture of usable daily driving capability.
