Unfortunately, the new battery was not in their original packaging at, but was in a small padded envelope repackages provided with the label.
Since in the end I do not care how the packaging is, if the content is true, I will use the battery only once. An uneasy feeling about this still remains.
If it turns out later that the three stars are not justified, I will adjust the valuation accordingly. To date, I forgive them because the compromise between the price and the strange feeling of a lack of original packaging when purchasing a new original.
