Unpacked battery and found that the Nokia hologram is missing, which carries the old battery and the product icon in the offer.
Built-in, loaded and working properly.
Could be better than the old completed, but if he is as good as its predecessor in the new state, I can no longer elicit honest.
After a few weeks, I can say that its performance is at least stable.
Pleased nevertheless gave me the low price, compared to the electronics store.
Mean rating, wg. missing hologram (not corresponding to the image in the offer) and it is not conclusive as to whether it is actually an original. Googling has since not even able to contribute much to the knowledge. Might not even be so easily detected in the house of Nokia. A note to this offer might expect help if someone reads it.
Conclusion: It is worth the money.
