Several websites reported today about a Nikon EN-EL15 battery recall. Please note that this is an old recall from 2012 and Nikon Japan recently just updated their website with some additional information (reported here last month). Nikon USA was probably late with the translation and just recently updated their website here. As far as I know, nothing has changed in the recall, but you can still check your batteries here.
BTW, the new Nikon EN-EL15a battery is also compatible with older cameras – see the full list here.
