Comparison of the fake (imitation) and real (genuine) Nokia BL-4C batteries

They look very similar, but one is a fake imitation and the other is a real genuine battery. There are only some slight differences that an unsuspecting consumer wouldn't notice such as some of the font text is different as well as the logos and the QR code on the back is more of what it shouldn't be. Both batteries do work, but I have not tested the battery life of them. Whatever you do, don't trust stuff on ebay and places like that where the item is from China. If you need a replacement BL-4C battery, just get one off of a phone that uses a BL-4C battery (like in this video I used a Nokia X2-00 which uses BL-4C batteries).
