Tesla shows battery data in the app, but it is self-reported and not independently certified. An Aviloo certificate is issued by a third party and carries the same legal weight whether you are buying, selling, or making a warranty claim.
The Tesla BMS is sophisticated and the app data is useful. But it is still the car reporting on itself. Software updates have changed how Tesla calculates and displays battery capacity. An Aviloo test is a physical cell-level measurement that is independent of Tesla's software, giving you a number that cannot be altered by an OTA update.
For buyers spending £20,000 to £40,000 on a used Model 3, an independent certificate is a straightforward way to confirm the battery is what the seller claims. It is also increasingly expected by used EV buyers who have done their research.
Less than most EVs. Tesla uses liquid thermal management and has strong battery chemistry, particularly on the Long Range and Performance variants. Most 3 to 5 year old Model 3s show 88 to 95% SOH. The Standard Range battery degrades slightly faster due to its smaller size.
Yes. Aviloo covers the Model 3 and the PAD test is compatible. The certificate is vehicle-agnostic and carries the same TUV certification regardless of make.
Tesla's app shows an estimated range figure and a rough battery health indicator, but it is self-reported by the Tesla BMS. It is not independently certified. An Aviloo certificate is issued by a third party and carries legal weight for warranty discussions, finance applications, and resale. Many Tesla buyers now specifically request one.
A 2019 to 2021 Model 3 Long Range should typically show 88 to 96% SOH. Standard Range examples are typically 85 to 93% at the same age. Any result below 85% on a car under 4 years old is worth investigating.
PAD comes to your address, tests in 20 minutes, and emails your official Aviloo certificate the same day. No deposit. Cancel anytime.
