Remember to inform us before shipment whether the battery has mechanical damage - then we will inform you if the battery requires special preparation for transport.



In the case of EVS and Storage batteries, if the fault will be  described by you in details, you will attach reports, screenshots from the servicetool, there is a high probability that we will be able to estimate the repair costs based on your data and present you with an initial offer before sending the battery to BMZ service.
