What can I say: the original battery that delivers what it promises. As well as the battery supplied with the camera he holds very long, even in subzero temperatures. If you hardly need the flash you create loosely over 1000 pictures on one battery charge, provided you do not use the Live View. No idea if replicas afford as much as I ordered it about a year ago, there were no matching. So if you want to have branded goods - it holds in this case, what it promises.
