It says OEM and Rim on the battery, but I guess that doesn't mean it's not a fake. One thing I did notice as far the physical appearance of the battery goes,on the original battery which is not a fake, but had died, you can feel the printing on the battery. On the one I purchased from Ebay, which is the one with which the white screen appeared, the print on the battery is smooth. I don't know if this means it is a fake.
