We are so glad that the AVILOO tool is available. As the busiest EV workshop in the UK, we regularly get asked for a state-of-health report on our customers’ batteries. To have a tool that provides a TÜV-recognised certificate to give to the customer adds a big value to our workshop.

Frequently Asked Questions

We’ve provided some answers to the most commonly asked questions.

The AVILOO Box measures several things about your battery, including its voltage, current, energy consumption, battery temperature, and cell temperature. All of these measurements are used together to determine the current state-of-health for your battery.

The AVILOO Premium test costs £99 incl. VAT plus postage.

The AVILOO Box is a device that is specifically designed to collect all the necessary parameters from your vehicle’s battery to determine its current condition. Once the data is collected, it is sent to our AVILOO platform via the internet for further analysis.

Without the AVILOO Box, it is not possible to collect or process the required data.

Your certificate should be sent to you via email within 2 working days of completing the test.
