Yes. The battery can be assessed with the car parked in the seller's driveway, in minutes, without driving it anywhere and without anything being written to the vehicle.
That sounds like a small technical detail. It is actually the reason a private-sale battery check is possible at all.
The obstacle nobody talks about
Here is the situation almost every private EV buyer ends up in. You have found the car. You want the battery checked. The seller is a stranger who has never met you, and what you are about to ask for is their car — for a day, or long enough to run it somewhere and back.
Most sellers say no. Reasonably. They have no idea who you are, their insurance almost certainly does not cover you, and there is a queue of other buyers who are not asking.
So the check does not happen, and the most expensive component in the car goes uninspected. That is the real reason most used EVs in Australia are sold without anyone looking at the battery — not cost, not ignorance. Access.
What actually happens at the appointment
We come to wherever the car is. A seller's home, a dealership, an auction yard, a workplace car park. The vehicle stays where it is and stays with its owner the whole time.
The diagnostic connects to the car and reads what the battery management system holds — its own State of Health figure, cell-level data, temperature behaviour and any stored or pending high-voltage fault codes. AVILOO, whose FLASH test we use for electric vehicles, states the test takes about three minutes.
It is read-only. Nothing is written to the vehicle, no settings are changed, nothing is dismantled and no repair work is performed. The car is exactly as it was, which is the thing a seller actually cares about.
The written report is produced at the appointment, so you have the result before you leave.
Why sellers say yes to this
Because you are not asking for anything. You are asking for permission to stand next to their car for a short appointment while someone plugs in a reader.
Frame it that way and the answer is usually yes — particularly if you offer to pay for it, which you are doing anyway. A seller with a healthy battery has every reason to agree, and one who refuses a three-minute read-only check on a car they claim is fine has told you something useful.
The honest limits
The appointment takes longer than the test, because our tester still has to meet the vehicle, identify it, run the check and produce the written report.
And this is a battery assessment, not a full pre-purchase inspection. It does not cover brakes, suspension, structural damage or service history. If you want those, book a mechanical inspection as well — they answer different questions and neither substitutes for the other.
There is also a real limitation in the method itself, which we have set out in full on our comparison of testing methods: a quick diagnostic reads and interprets the vehicle's own management data rather than physically cycling the pack. That is a meaningful distinction and we would rather you knew it.
