My authentic LP-E6s read "cell made in Japan, further processed in China."I checked six of my LP-E6 and while 6 have "Cell made in Japan, further processed in China." imprinted on the sticker, 2 just state "Made in China". I consider all of my LP-E6 genuine.
The thread now has a [SOLVED] label. Would be nice if you would tell us how you decided to proceed.
I did a side by side with my genuine Battery that came with my Mk3.
Yes it does say 'Made in China' as well but there are slight minor differences.
The 4 code in the bottom left is a different size and thickness, extra chinese characters and code on the top right of the blue.
The charge time of my original genuine battery was about 5-6 hours, whereas the charge time of the extra battery was about 2 hours.
Also the holographic isn't exactly the same on the website (will check at a specialty retailer).
I am also going to contact my guy at Canon Australia and suss it out.
I guess it isn't 'Solved' just yet. Sorry guys jumped the gun.
