EV Battery Health Test | Check EV Battery

Now available at selected mycar stores across Australia.

Your EV's battery is the single most valuable component of the vehicle and the biggest factor when on its resale value. A Battery State of Health (SoH) Report gives you clear, independent proof of your battery's condition, helping protect your investment, support resale value and identify potential issues early.

That's why we've partnered with Voltest to offer SoH reporting at selected mycar locations nationwide.

What is a SoH test?

A SoH Report assesses the overall condition of your EV battery and provides a simple percentage score.

100% indicates performance consistent with a near-new battery
Lower scores indicate reduced available capacity over time

You'll also receive data including cell condition and voltage balance, helping you understand battery performance and life span.

When is a SoH report worth doing?

Buy or selling an EV?

A SoH report adds transparency to a used EV sale. Buyers get clarity on battery condition, and sellers can provide evidence that supports confidence (and value).

Noticing reduced range?

If your EV isn't going as far on a charge as it used to, a SoH report can help identify whether the change is battery-related, and flag potential issues early.

Adding it to a service

You can book a SoH report as a standalone appointment, or add it to a service, tyre visit or repair.

How do I book?

Call or visit your local participating mycar store we'll help organise a time.

Electric Vehicle Car Battery FAQs

How long does an electric car battery last?

Most electric car batteries are designed to last between 15 and 20 years, or around 240,000 to 300,000 kilometres - whichever comes first. In practice, how long your EV battery lasts depends on factors like your charging habits, climate, driving style, and the make and model of your vehicle. Most manufacturers offer a battery warranty of around 8 years or 160,000km, which gives you some protection if capacity drops significantly within that period. Regular battery health checks can help you catch degradation early, and get the most out of your battery over time.

What is a battery state of health check?

A battery state of health (SoH) check is a diagnostic test that measures how well your EV battery is performing compared to when it was new. It assesses key indicators like remaining capacity, charge acceptance, and estimated driving range, giving you a clear picture of your battery's current condition.

At mycar, our technicians use specialist equipment to generate a detailed report so you know exactly where your battery stands - whether you're buying a used EV, preparing to sell, or simply want peace of mind.

How long does an EV battery state of health check take?

An EV battery state of health check at mycar typically takes around 20 minutes, depending on the vehicle. It's a straightforward, non-invasive test; there's no disassembly involved. You can over the phone or drop into any of the locations above.
