Why drivers book us
In an EV or hybrid, the high-voltage battery is the most valuable component on the car. Two identical vehicles can have very different battery health — and you cannot see it from the outside, the odometer or a test drive.
The test reads the battery's own State of Health from its management system and analyses it against factory specification. You leave with a certified figure, not an opinion.
Every report carries a certificate and a public verification code. A buyer, seller, dealer or lender can check it themselves in seconds — no account, no phone call to us.
Seller's driveway, dealership, auction yard or workplace anywhere across Sydney, Central Coast, Blue Mountains + Wollongong. The test is read-only — nothing is changed on the vehicle.
Vehicle coverage
Every electric, plug-in hybrid and hybrid vehicle can be booked. The vehicle, not the badge, decides what can be read, so we read the battery system in front of us and explain the results in your report.
01 / 03
Battery health testing for everyday electric cars, with the available readings checked against the exact year, model and diagnostic protocol.
Who it's for
Buying
Dashboard range estimates and a polished sales pitch tell you nothing about battery health. Get the tested State of Health before money changes hands — at the seller's home, a dealership or an auction yard.
Book before you buySelling
A verified battery certificate answers the first question every serious buyer asks. Show the tested State of Health and the public verification code, and let the report do the negotiating for $249.

Know where your battery actually stands. Your report includes a five-year state-of-health projection and the distance to 70% capacity, so you can plan ahead instead of guessing.
Check your batteryWhy it matters
Dashboard range estimates, the odometer and the charge percentage all describe something different from battery health. Range readouts change with driving style, temperature and load. Odometer readings say nothing directly about the battery. A charge percentage tells you how full the battery is right now — not how much capacity it still has compared with when it was new.
The test reads the battery management system's own State of Health and cell-level data and analyses it against the original factory specification, then goes deeper into usable energy, cell voltage spread, temperature behaviour and high-voltage fault data. It also models a realistic range and five-year SOH projection from the tested data.
Add State of Health, usable energy, cell balance, fault data and projected range to your decision before you commit.
Establish the battery’s tested condition now and see the five-year trajectory modelled from its State of Health and charge-discharge behaviour.
Share a dated, written test result with prospective buyers so the conversation is based on evidence rather than assumptions.
Dashboard versus battery management data
What the dashboard tells you
“About 320 km”
A changing estimate shaped by recent driving, temperature, load and current charge. It does not show original capacity loss or whether the cells are performing evenly.
What the diagnostic reads
Condition, made legible
Move the indicator to see how State of Health changes the plain-English verdict.
State of Health interpretation
Excellent
92%
90–100%: Close to original factory capacity.
Below 70% · Grade D
Walk-away territory
Below the manufacturer warranty floor, with battery replacement likely.
70–79% · Grade C
Watch closely
Meaningful range loss. Buy only at a price corrected for the battery condition.
80–89% · Grade B
Healthy
Normal wear for the vehicle’s age and kilometres.
90–100% · Grades A+ / A
Excellent
Close to original factory capacity.
The diagnostic standard
AVILOO is an Austrian battery-diagnostics specialist. The FLASH test reads the battery management system's own State of Health and cell-level data — a completely different and far more detailed thing than the range estimate or charge percentage on the dashboard — analyses it against the pack's factory specification, and delivers it as a written, certified, independently verifiable result. It is a read-only analysis of the vehicle's own data, not a discharge or stress test.
AVILOO FLASH applies to battery electric vehicles only. Hybrid and plug-in hybrid vehicles are assessed with a professional hybrid battery diagnostic that reads the pack's condition and reports it in writing — same price, same mobile service.
CARA Approved
The AVILOO FLASH test holds CARA Approved certification for battery health checks. CARA Europe — the Car Remarketing Association Europe — is a non-profit set up by key players in the used-car industry; its Battery Health Check scheme certifies State of Health test methods so a used electric vehicle can change hands with buyer confidence. The approved list also includes DEKRA, TÜV NORD, MAHLE Aftermarket, Autel and LAUNCH Europe.
The certification belongs to AVILOO's FLASH test method, not to EV BATTERY LAB — and you don't have to take our word for it: verify it on the public CARA list.
Read-only by design.
The test reads diagnostic data while the vehicle is driven. Nothing is written to the vehicle, the battery is never dismantled, and no repair work is performed.
Testing
$249
For battery electric vehicles. The CARA Approved AVILOO FLASH test reads the battery management system’s own data — State of Health, usable energy, cell voltages, temperature behaviour and faults — and analyses it against the pack’s factory specification.
$249
For hybrid and plug-in hybrid vehicles, using dedicated hybrid battery diagnostic equipment — not the AVILOO FLASH test. Same price, same mobile service, same instant written report, with the available measurements read from the vehicle’s own diagnostic protocol.
The AVILOO FLASH test used for battery electric vehicles holds CARA Approved certification — CARA Europe, the Car Remarketing Association Europe, is a non-profit set up by the used-car industry that certifies State of Health test methods, so a result can be trusted when a used EV changes hands. The certification belongs to AVILOO's FLASH test method; anyone can verify it on the public CARA list.
EV & hybrid coverage
Battery assessment for fully electric, plug-in hybrid and hybrid vehicles across leading marques.
Every electric, plug-in hybrid and hybrid vehicle can be booked, listed marque or not. The measurements available vary by year, model and diagnostic protocol.
Vehicle compatibility
Choose the year, make and model to see the measurements we publish for that vehicle. Every electric, plug-in hybrid and hybrid vehicle can be booked, including models that are not in this list.
How it works
01
Vehicle type, make, model and year, plus the suburb in Sydney, the Central Coast, the Blue Mountains or Wollongong where the vehicle will be.
02
After confirming compatibility, our mobile tester attends the seller’s home, dealership, auction yard or workplace.
03
Your test results, practical interpretation and five-year projection are delivered in writing at the vehicle during the appointment.
This is a fully mobile service. There is no workshop and you never have to drive anywhere. Booking online reserves a date and an AM or PM session; we confirm the arrival time before the test.
Your report
Your test produces a battery certificate recording the certified result, energy, range comparison, completed diagnostic checks and vehicle details.
Actual AVILOO FLASH certificate format
These are genuine AVILOO FLASH certificate previews from battery electric vehicle tests performed by EV BATTERY LAB. Certificate numbers, VINs and QR codes are hidden for privacy. Individual results vary by vehicle.
Hybrid and plug-in hybrid vehicles are tested with dedicated hybrid battery diagnostic equipment, and their certificate follows a different format with the measurements available on that vehicle.
The certificate records the tested vehicle, mileage, test time, State of Health, current energy, comparative range, completed battery checks and AVILOO’s evaluation at the time of testing.
