I have a 5D SR which is a close relative to the 5D Mark IV and I use both the Wasabi and the Canon Battery that came with the camera. I can never tell which ones are in the camera unless I look at the label on the battery. I had Wasabi Batteries in my 6D as well, before it was stolen and had no problem at all. Don't know what the thief is using.

Use Wasabi on Canon 80D They Register and work as good as Canon

I hear, but cannot confirm in the case of all batteries, that the non-Canon batteries gradually grind to a halt in the near future, whatever that means. In my 5d2 several aftermarket batteries wouldn't show me a useage gauge but otherwise seemed to work fine, just not as long or as many shots, however you want to see that factor. Others I tried showed me a gauge and worked fine at first but didn't hold a charge as long as the original Canon battery and the last ones I got, 3 of them all seemed to do very well in all aspects but have now reached a place where the camera rejects them totally and shuts down when I put one in. In the meantime, the original Canon battery is still going strong since 2009 but might not be had I not "spelled it from duty" with the aftermarket batteries. Needless to say, throughout all the experimenting I have spent more on batteries that do not work than I would have had to spend on more original Canon batteries for the same period. Looks like you get a choice, "pay now or pay later."

You may be right. I don't normally gamble because my luck with the horses and blackjack tables is less than stellar. I also don't normally buy lottery tickets for the same reason. With 3rd party camera batteries, my track record, thus far, is extremely good however. The only problem I have had is when the camera manufacturer tries to dictate which battery will work in the camera. It seems to be a game being played between the battery manufacturers and the camera manufacturers. You can be sure the camera manufacturers don't manufacture batteries. They buy them from some of the same manufacturers that make the 3rd party variety. The next time I update my camera firmware, I may find that my 3rd party batteries mysteriously cease to work as they should I suppose. Still, I can buy more than four 3rd party batteries for the price of one OEM version. The worst thing I've had happen so far is that the power gauge and charge info failed to read. If I choose to use the battery anyway, the camera still takes pictures. I just don't know when it will stop...out of gas. If the worst thing happens, I can still take pictures and for 25% of the cost. Even if those 3rd party batteries last only half as long as the OEM models, I am going to realize a savings. To me that falls outside of the realm of gambling and into the area of calculated risk. I also have purchased two 3rd party battery grips for my 7D2 and 5Ds. Both work well for a LOT less cost to me. Add to that fact the flexibility to insert double "A" batteries into the grip as a substitute for the regular camera battery and I have some assurance that I can take pictures, even when all of my camera batteries are drained.

I would be just as miffed if Honda told me that the only oil or oil filter I could use in my Accord was the Honda brand. Come to think of it, they may have insinuated that at some point. So I use a 3rd party brand and haven't noticed a negative result there either. I found it interesting that, although there is a Honda brand synthetic oil, the dealer advised me that the oil in my new car was Mobil 1!!! Yikes, a 3rd party brand!
