I have ordered two: I received 2, two different batches. with each label + and - according to the website photos, the other all black, but with the NOKIA logo engraved in the plastic case. The second fact RAS, but the first (with the label + and -), probably older, with the original packaging, was at 3.1v instead of 3.8V was completely unloaded, and did not want to load. So I was afraid. In fact with another Nokia charger (for another range of phone), which delivers 5.7V instead of 3.7V is the nominal voltage for these batteries, she end up depolarizer and load normally! May still had to have this charger at hand!
