Do the four Chinese symbols in the bottom-left corner of a Samsung battery mean manufacturing date? (Characters identified: 生产日期) For the purpose of this question I'd like to know whether the four Chinese characters in the bottom-left corner of the i9250 Samsung battery really mean manufacturing date:



Here, here or here are high-resolution images of the battery, which should be easier to read and confirm.

I am more than sure whether these four symbols actually mean that, so I only need a confirmation, since I don't know Chinese at all.

Disclaimer: I understand and full accept FAQ's regulation, claiming, that questions asking for translations are off-topic in this site. I think I did enough prior research. I only need a confirmation, not a translation.
Yes, it writes 「生产日期」 which means manufacture date.
