Well done, the shipment to Germany was really fast I received the battery after 14 days. The installation of the battery in the vacuum cleaner was very easy, you can find a related video on YouTube.the whole replacement took me around 15 minutes.my vacuum cleaner is now running as new.the seller was absolutely good.By the way, I found out that the battery compartment in the vacuum cleaner can hold the second battery.I guess if you switch to batteries in parallel you can twice the capacity.
