Canon has changed packaging as well as whats printed on the batteryabout once a year. Three of my four are slightly different, each is a different age. The new batteries I bought form Adorama and Amazon (not a third party) have the correct hologram. The other two came with my 5D MK II and later 7D.
The original 5D Battery says made in Japan, then I have a made in China, and one that is part Japanese and part Chinese. One has a date on it, but the others are older and do not.
