Questions, answered.

What does battery state of health mean?

State of Health (SOH) shows how much capacity the battery still has compared to when it was new. It is the number buyers of a used electric car care about most.

Which vehicles can be tested?

Fully electric cars and plug-in hybrids registered in the Netherlands. We check your plate against the RDW register before you pay.

What happens if no partner is available?

We widen the search automatically. If nobody accepts in time, you choose a new time or receive a full refund.

How long does the test take?

Usually under an hour. Your partner confirms the exact time after accepting the job.

How does a buyer check my certificate?

They scan the QR code on the PDF or enter the certificate number on our verification page.
