A full pre-purchase inspection plus a measured battery State of Health test — at the seller's address, anywhere in Sydney. You get the number, the cell-level data behind it, and a 5-year forecast of where that pack is heading.
Measured, not estimated
Read straight from the battery management system
We run our EV and hybrid battery tests with AVILOO, the Austrian battery-diagnostics specialist used by manufacturers, fleets and insurers across Europe.
Independent diagnostics
The result comes from AVILOO's analysis of the pack — not the seller, not a dealer, not the car's own dashboard.
CARA approved method
The AVILOO FLASH test is an approved battery health check, giving a state of health you can put in front of any buyer.
Verifiable certificate
Every test issues a numbered battery certificate with a scan-to-verify code, so the result stands up when you resell.
Battery testing available on
We test electric and hybrid vehicles from Tesla, BYD, MG, Polestar, Hyundai, Kia, Nissan, Toyota, Lexus, Volvo, BMW, Mercedes-Benz, Volkswagen, Cupra, GWM Ora, Mini and others.
Coverage depends on the vehicle's diagnostic protocol — tell us the year, make and model when you book and we confirm before the job is locked in.
On a petrol car, the engine's condition shows up in noise, smoke and oil. On an EV, the most expensive component in the vehicle degrades silently — and neither the odometer nor the dashboard will tell you how far along it is.
A high-voltage battery replacement is by far the largest single repair on an electric car. Discovering a weak pack after purchase is not a $500 surprise — it changes what the whole car is worth.
Two identical cars with identical odometers can sit several percent apart on State of Health, depending on charging habits, DC fast-charge frequency and how the car was stored.
"The battery's fine" is not evidence. A dashboard range estimate is not evidence either — it's a rolling average of recent driving. A measured SoH figure is.
The percentage on its own means nothing until you know which band it falls in. This is the same scale our inspectors use when they write the recommendation on your report.
Below 70%
Under the floor most manufacturers warrant to. Replacement or heavy depreciation is the realistic outcome.
70–79%
Meaningful range loss. Worth buying only at a corrected price, and only with the forecast in hand.
80–89%
Normal wear for age and kilometres. Fine to buy — but the loss belongs in the price you pay.
90–100%
Effectively factory-fresh capacity. Buy with confidence and use the certificate at resale.
Every EV inspection includes a five-year State of Health projection built from your car's measured capacity and the degradation behaviour of that pack. It's the difference between knowing what you're buying today and knowing what you'll be selling in five years.

Straight arithmetic on the figures you enter — no pricing assumptions. A car advertised as "like new" at 86% SoH is 14% down on the battery it was sold with. That is the gap you take to the negotiation, and it's the gap we measure.
Renegotiate
A measured capacity shortfall is something a seller can't talk their way out of. Our Elite tier goes further — we negotiate with the seller on your behalf using the findings.
Walk away
If the pack is under the warranty floor or the cell spread says a module is on the way out, you find out before the deposit, not after.
The measured percentage of original capacity the pack still holds — the single number that decides what the car is worth.
Usable kWh today against the pack's original usable kWh, so the loss is expressed in energy, not marketing language.
The delta between the strongest and weakest cells. A wide spread is an early warning of a failing module long before a dashboard light appears.
Minimum, maximum and delta across the pack during testing — thermal imbalance is a known precursor to module failure.
Stored and pending fault codes from the battery management system, inverter and charging electronics, including codes that were recently cleared.
What the car will actually do on a Sydney commute today — and what our forecast says it will do in five years.
The battery test sits on top of a complete pre-purchase inspection — brakes, tyres, suspension, steering, 12V system, structural and accident-damage indicators, PPSR history and a road test. EVs are still cars, and they still get crashed, curbed and neglected.
No mock-ups and no marketing sample. These are the actual documents an EV buyer receives.
01
Pick your tier and add the EV / Hybrid Battery Test at checkout. Give us the year, make and model so we can confirm diagnostic coverage before we lock the job in.
02
A mobile inspector meets the seller at their address — private driveway or dealership — anywhere across Sydney metro.
03
The complete mechanical and safety inspection, plus a read-only session with the battery management system for the pack data.
04
Your full report and a battery certificate with the 5-year forecast and a public verification link you can hand to your own buyer later.
The EV / Hybrid Battery Test is a $199 add-on on any tier. GST included, no travel fees inside Sydney metro.

Every day, I speak with people buying a car they'll rely on for years to come. Some are parents searching for their teenager's first car, some are buying a safe family vehicle, and others have spent years saving for the right one.
I know how important this decision is, and I never take your trust for granted.
I've seen the disappointment of discovering hidden problems after buying a car. That's why we don't just inspect vehicles—we help protect people from making an expensive mistake. Every inspection is carried out as if we were helping our own family.
If I wouldn't recommend a car to someone I love, I won't recommend it to you.
And if the first car isn't the right one, we'll give you 15% off your second inspection because I don't want the cost of another inspection to stop you from finding the right car.
Your trust means everything to my team and me. We'll be honoured to help you make this important purchase with confidence.

You guys are legends! You not only carried out a thorough inspection of my car, but you also helped negotiate the purchase price with the dealer. The money spent on your service was absolutely worth it. I highly recommend anyone buying a used car to use your service — you can buy with confidence and without hesitation. Thank you for making the whole process so easy!

Man o Man, these guys are so amazing, like an angel. They helped me with not only doing a mechanic check for a car that I purchased for my dad in Sydney from NZ. They also helped with the car transfer for my elderly dad and made sure the paperwork was all good. Their report was great and I used it to get the seller to fix all the major faults. No question is too small or big for them. Himanshu was so great with all my queries 👍. Keep up the good work boys.

Had a great experience with Aussie Auto Care for a vehicle inspection. The report was thorough, easy to understand, and delivered promptly. The team was professional, helpful, and took the time to explain their findings clearly. Gave me confidence in my purchase decision. Highly recommend.

These guys made buying a used car so easy. They found issues the seller never mentioned and helped me avoid a bad purchase. Would use them again for sure.
State of Health is the usable capacity of the battery today measured against the capacity it had when it left the factory, expressed as a percentage. A pack at 92% SoH stores 92% of the energy it originally could, which translates almost directly into range. Odometer readings, service books and seller assurances tell you nothing about SoH — only a measurement does.
We test battery-electric and plug-in/conventional hybrid vehicles from mainstream brands sold in Australia — Tesla, BYD, MG, Polestar, Hyundai, Kia, Nissan, Toyota, Lexus, Volvo, BMW, Mercedes-Benz and others. Coverage depends on the vehicle's diagnostic protocol, so tell us the year, make and model when you book and we'll confirm before your inspection is locked in.
No. The test is read-only — we connect to the vehicle's diagnostic port and read what the battery management system already records. Nothing is written to the car, no software is modified, and no forced discharge is performed.
Plan on the full inspection time for your tier plus roughly 30–45 minutes for the battery work. The vehicle needs to be accessible and in a state where we can read the pack, so we ask the seller to leave it parked and unplugged when we arrive.
Your measured State of Health today, projected forward using the degradation rate we observe for that pack chemistry and usage pattern. It is a projection, not a guarantee — we show the model and the assumptions on the certificate so you can see exactly how the curve was built.
Yes. We inspect at private addresses and at dealerships across Sydney. We ask the dealer for the same access we ask a private seller for: keys, the diagnostic port and enough time to complete the inspection properly.
You get the number in writing, with the fault codes and cell data behind it, plus the inspector's recommendation. Most of our buyers use it one of two ways — walk away, or renegotiate the price with a measured figure the seller can't argue with.
Yes. The battery result is issued as a certificate with its own verification link. When you resell the car, you can hand that link to your buyer and they can confirm it independently on our site.
Book an EV inspection anywhere in Sydney and get the State of Health, the cell data and the 5-year forecast before you transfer a cent.
