Bought 2 of these batteries from "Best N Price" in Dec 2011 and they are genuine Nokia batteries with the Nokia name and 3D logo on the battery. I bought another 2 batteries a little over a month later from another vendor (Just Cellular) at a higher price than the first set.The batteries from 'Just Cellular' did not have the Nokia name or the 3D logo on the battery - only the BL-5C.
