I'm new to the forum but felt compelled to reply to this post after finding it, having also received 'fake' LP-E6 batteries for my 7D. I ordered them from a third party, 'Tech_traders1' through Amazon but like with unkbob the battery covers were a different colour to the genuine Canon one I received with my 7D and the texture on the battery was different too.
I contacted Canon directly to see if they could advise but my the iPhone photos I sent them meant they couldn't conclusively say whether they were counterfeit or not. I was told however...
"From the images that you have provided, it is not clear if these are counterfeit. If these are counterfeits, they do appear to be good replicas - unfortunately the slight softness of the image prevents me from confirming 100%. The battery cover does definitely raise concerns, as the colour is incorrect.
Perhaps one of the best ways to tell is from the hologram. The hologram should change as you tilt it, I have attached two photographs to confirm how the hologram should appear. From the images you provided, this did not appear to be the case, and also the actual design of the hologram does not seem right.
Comparing a genuine with a suspect battery is simply the best way to determine if it is counterfeit, as genuine Canon batteries should mostly be identical aside from occasional slight design changes. Slight differences in typefaces or logos, printing or labels that are situated at a slight angle, or the quality of printing and materials used for the packaging, are generally the best indicators."
Having contrasted the holograms on the suspected fake packaging to that of a genuine packet (that I have subsequently bought) leaves me in no doubt that the third party batteries from Tech-traders1 are fake.
I have requested a refund from the seller and Amazon have confirmed that a refund request has been made. Having only recently acquired my 7D (I use the Canon C300 video camera more) I wanted to use genuine Canon parts.
The moral of my story is that if prices for so called genuine products seem too good to be true then they usually are. Attached is a photo of the genuine hologram that I received from Canon in my correspondence:
Hope this helps someone down the line.
