Certified Battery Check - Determine the health of your battery.
Now you can easily read out the battery health status of your electric construction machine* in just a few simple steps using a test device (logger). No problem with the Certified Battery Check - and it's even TÜV approved. Simply register, receive the test device, connect it to the electric construction machine and receive an independent and TÜV-approved certificate within two days.
* Initially only available for our Zero Tail excavator EZ17e, other models will follow.

This is how it works:
- Request the Certified Battery Check test device from your sales partner.
- You will then receive a pre-configured test device by post.
- Now connect the test device to the OBD2 plug of your electric construction machine.
- The battery analysis is started via the transmitted web app link.
- Follow the instructions in the app.
- Return the test logger after the test has been completed.
- You will receive the "State of Health Certificate" for the tested battery within two working days.
