Tesla is now providing a detailed digital certificate through its official app that documents every repair and battery replacement a vehicle has undergone.

In the past, used EV owners were often left without any official paperwork confirming the battery’s condition after repairs or regular use. That lack of transparency hurt resale values and made many potential buyers wary of purchasing a used electric car.

The new certificate changes that. It gives shoppers a quick, convenient way to check the battery’s service history, so they can see exactly what refurbishment work was done and feel confident in the repair’s reliability.

The document is linked directly to the car’s profile and can be exported as a PDF, which streamlines used EV transactions. This added layer of transparency benefits both sellers and buyers by improving trust and making deals smoother.
