Worthy addition to the original with good capacity. The original battery has 1800mAh with a greater capacity, their border is at first difficult to reach as a hobby photographer. If this should happen to anyone, you are well advised with this very inexpensive replacement battery with 1600mAh. He is recognized by the camera (in my case EOS 60D) and supported, a registration in the camera menu with serial number is also not a problem. Runtime compared to the original about 20% shorter, the smaller capacity so everything is fine! Buy recommendation!
