I've used Wasabi batteries for a long time. On my 60D, they work fine. On either of the 5D3 or 6D, it shows an error prompt. After selecting "okay", everything works fine.
when I got my 5D3, I had one old Wasabi that did the same, but the other two more recent ones had no problem. I have bought four since, and they also have no such issues, in 5D3, 7D2, or 5D4.
I recall that it was a problem for older ones when 5D3 came out specifically. Many that had worked fine in 5D2 were not able to fully function in 5D3. Of course 5D3 added a lot of new battery info to it, so it made sense. At that time, Wasabi was replacing older ones for free with newly "chipped" versions that would be fully compatible with the new features of the 5D3.
this was exactly the time that I became full supporter of Wasabi. Not only did they give me a new free battery, but they were the first to decode the new battery functionality of the 5D3.
