Result: An original battery was, as expected, provided by Amazon. In original packaging and in Samsung Samsung Battery plastic. So any neutral plastic bag or the like. The comparison with my previous (original battery, there was included my N7100) is 1: 1 the same. With the exception of the production date;)
The plastic box is, by the way, a perfect storage for the previous (now Reserve) battery. The former is not completely broken after 2 years in operation Note2, but keeps hold "only" means any day through. He is now in the box and is so well stowed in the laptop bag.
Original as secure sales source, then it will come with the battery)
