Battery owner?

Hi all,

Here is a twizy on ebay:
My german is not so good, but from what I can see, the seller claims the accu is included and you don’t have to rent it from Renault. How is this possible? I thought rental is the only option for accu…

It could have been purchased in Norway. The battery was sold there but not sure what terms and conditions were applied to selling on outside Norway.
