A battery, but original?

The battery acts apparently as an original Canon battery but why is the date code pasted? A protective cap is not in (as in real original), and the original was actually in Canon blister and not in a white cardboard box. Canon even firming the authenticity of a battery at the hologram on the packaging. This hologram is here nowhere to be seen. Well, that could be as a manufacturer and do better and identify the battery itself. Thus, these are more like an OEM product. I'll keep the term in mind, first there's four stars.
