I looked very hard to find a battery for Canon, the majority of 3 or batteries are bad news. It was so expensive that I thought to be authentic. It came four days late. I question the authenticity of the "canon" of the battery - cheaper boxes had colors faded instructions on poor quality paper, the label of the battery muted colors, it's not like any of my Canon's OEM parts, there was no effect on the cheap plastic tray can be used to specify the orientation of the cargo hold / no. I can not prove that they are fake knock-off - but also the "hologram" appears to be wrong. I have more confidence in the performance of Amazon directly ..
