Independent EV battery testing · Melbourne

Know the battery before you buy the car.

The battery is up to 40% of a used EV's value — and the one thing you can't see at inspection. BattCert measures the real State of Health and gives you an independent certificate, at your driveway or the seller's, anywhere in metro Melbourne.

How it works

One visit, one certificate, same day. Built for private buyers, sellers, and dealers across metro Melbourne.

STEP 01 — BOOK

Tell us about the car

Make, model, year and location. Buying privately? We can meet you at the seller's address and test before you hand over a cent.

STEP 02 — TEST

We measure the pack directly

A certified diagnostic read of the battery management system — not a guess from the dashboard range. Tesla owners can opt for a fully remote test via secure account authorisation.

STEP 03 — CERTIFICATE

Same-day, verifiable report

State of Health, position against other vehicles of the same model, age and mileage, and warranty headroom — in plain English, with a QR-verifiable online copy sellers can attach to any listing.

Simple pricing, no commissions

We never buy, sell or broker cars. We're paid by you, for the truth about the battery — nothing else.

Ex-novated-lease EV? Thousands are entering the used market right now — a battery certificate is the fastest way to stand out from identical listings. Don't see your model? Book anyway — most EVs with an OBD port can be tested.

Questions buyers ask us

Isn't the dashboard range estimate enough?
No — the displayed range is an estimate influenced by recent driving, temperature and software, and it can drift meaningfully from real usable capacity. We read the battery management system directly and compare the result against other vehicles of the same model, age and mileage.
What exactly is "State of Health"?
State of Health (SoH) is the battery's current usable capacity as a percentage of its original capacity. A 5-year-old EV at 90% SoH has lost about a tenth of its range since new. Most manufacturers warrant the pack to stay above 70% for 8 years — our certificate shows how much headroom your car has.
Do you buy or sell cars, or take commissions?
Never. We're an independent testing service — we don't trade vehicles, take referral fees from sellers, or broker deals. Our only customer is the person paying for the certificate.
I'm selling — is this worth it?
European auction data shows certified used EVs attract more bids and sell faster than uncertified ones. Attaching an independent certificate to your listing answers the first question every serious buyer asks — before they use it to negotiate you down.
How does the remote Tesla test work?
You grant temporary, read-only access through Tesla's official third-party authorisation — the same mechanism used by charging and insurance apps. We pull diagnostic data, and you can remove access the moment the report is delivered.
Is the certificate a warranty or guarantee?
No — it's a point-in-time independent diagnostic assessment, like a building inspection for a house. It tells you the battery's measured condition on the day of testing and how that compares with similar vehicles.
