Test your battery conveniently during your daily drives by renting our tool
The TÜV-certified AVILOO Premium Battery Test provides a comprehensive and reliable evaluation of your EV’s high-voltage battery. The test measures the battery’s true capacity during real-world driving and calculates its SOH (State of Health), giving you accurate insights into the current condition, including signs of aging or hidden faults.

During the test, the high-voltage battery is driven from full to nearly empty (around 10% charge) over a period of seven days. The device collects critical data during this time, such as voltage, current, temperature, and other key parameters. This data is analyzed by AVILOO’s automated systems and experts, and you’ll receive a detailed Battery Certificate via email within a couple of business days.
You can purchase the Premium Test in two ways:
#1 At our workshop in Vantaa: Bring your car to us, and our professionals will help you set up the test device.
#2 Rent the test device online: Order the test device from our webshop and perform the test yourself.
- Place an order online – Check the stock availability to see the next available delivery slot.
- We’ll send you the Aviloo test device along with detailed instructions.
- Drive as you normally would while the device collects data. Rental periods are 7 days for hybrids and 10 days for EVs.

Tip: There’s also a more affordable and quicker Aviloo Flash Test (€95) available, which gives you an overview in no time. This can even be done during a test drive! Flash tests are performed on-site at our Vantaa workshop, often while you wait.

The key benefits of testing your EV battery
- Proof of battery condition: Get a reliable report on your battery’s health, which is valuable for resale or your own peace of mind.
- Catch issues early: Detect hidden problems before they impact your car’s performance or lead to costly repairs.
- Plan for future costs: A perfect solution for checking your battery before your warranty ends or buying a used car.
- Easy to use: The test is simple to perform, and the certificate results are easy to interpret.
- Boost confidence: The TÜV-certified Battery Certificate provides objective information about your battery’s condition and builds trust in car transactions.
How does this compare to other diagnostic tools?
There are many tools on the market and in repair shops that can read the SOH value from your car’s diagnostic system or check metrics like charging cycles or fast-charging history. However, the AVILOO Premium Battery Test goes deeper. The test values are based on real driving data analyzed with TÜV-certified accuracy. Unlike your car’s onboard systems, this test detects hidden or developing problems that might not yet affect performance.
The AVILOO Flash Test is a convenient quick check, ideal when buying a used EV before you sign the papers. The more detailed Premium Test provides extensive insights and is great for post-purchase validation or monitoring your car’s health over time.
- AVILOO Flash Test (€95): A quick check at our Vantaa workshop, often while you wait, for critical insights and an overall snapshot of your battery’s condition.
- AVILOO PREMIUM Full Test (€129): Provides accurate, detailed data about your battery based on real-world driving. Perfect as documentation when selling your car or trading it in – many dealerships appreciate having this kind of report.
