Have gained me the battery as second battery for my EOS 600D. Will probably be an original, because it was eingeschweist in the package and it color and font default is no different from my supplied to the camera. Likewise, the details are identical. However, it considers, to my amazement longer than the supplied one. Complete 100 pictures more, and at the video function it lasts longer in my experiments through. Had it tried before with a battery of a third party, where I was attracted by the price, but I quickly regretted the differences in performance. Up to 40% less power are not what I imagined. That is why an original. Pays my opinion, when you're out and photographed a lot.
