Is Your EN-EL15 Battery Compatible With Your Nikon Z 8? Mine Isn't! 

ENEL 15 with the Lion 20 works in my Z8

Thank you very much for the video! Fwiw, my two EN-EL15s from 2014 work fine in the Z8. Cheers

I did some further testing, it is the Li-ion01 variance of the EN-EL15 is incompatible. the Li-ion20 variance works fine.

This was also happened with D500. It was giving only 5-6 clicks per charge. But later Nikon gave firmware update to rectify this problem.

Thank you for this information. I own 3 EN-EL15 from my d750 & only one works in the Z8 the other 2 do not. Well, I'll see if there is a grip along with 2 more 15c in my future.

my old 2015 EN-EL works - ca. 900 shots. does anybody know a 3rd party battery which workd on the Z8?

First of all...I really like your videos. Thank you. I have used Nikon DSLRs and Z cameras for many years, and so, like you, I have a collection of EN-EL15 batteries. When I saw this video, I had to laugh. I received my new Z8 a couple days ago, and today I put in an EN-EL15 battery. Sure enough, I got exactly the same results as you. I tried an EN-EL15a then an EN-EL15b. They worked. Just not the EN-EL15. No big deal, really. It's just that your video describing your experience was exactly my experience. Anyway, I really like my Z8. I also have a Z7. I recently sold back to B&H my beloved D850 along with some F-mount lenses. At any rate, I am very happy with my current Nikon gear. I can even still use the EN-EL batteries in my Z7. So that's good! (BTW, all the batteries I have are ones manufactured and distributed by Nikon...not third party.) Take care.

Nice information. Thanks.

Thank you for this as I was wondering if the 15b would work in a pitch once I purchase the Z8 since I have 6 for my D850. Though I upgraded my D850 to the 18 in the grip. Nice to know the 15b will be useful if needed.

Thank you for this video, thought my EN-EL 15 is dead just checked mine is from 2011 doesn't work with z8 but works with z6ii

I feel like my old EL15 used to work with the camera until the most recent update. Now it shows as dead but is fully charged per my D7200.

Mystery solved! Thanks Taku.

A simple (but of recent tech) USB cable would seem like a passive device and never pose a challenge but actually there's "logic" (like a chip) in the connectors that can negotiate capabilities in speed, voltage and ampères. Batteries may have "battery management" (BMS) logic inside that communicates with a charging devices. You can imagine, devices on either end need to be able to communicate in the same language (AKA protocol) and the same version thereof. Such problems in the world of IT are as old as IT and have caused big problems in big corporations. Upgrade component A and you may need to work on B through Z too. And then, if you don't want to upgrade, say, F in that environment because that is an expensive paid upgrade, you end up in a "release squeeze". Which is, basically, what is going on here. Nikon is reasonably transparent about this. Third party brands are not and are a gamble where you do not know if you can trust their product type indication being 15, 15a, 15b, or 15c. They may have the proper mAh and V in there, they may have the proper BMS in there, but if the negotiation logic is wrong, it will not work properly in all cases. To me, it's not worth the hassle of 3rd party products. And I have been fortunate with used 15, 15a, 15b, and 15c to all work in my Nikon camera that prefers 15c, e.g. for in camera charging over USB.

My EN-EL15 from 2017 works just fine.

So, I have six (6) third party BM Premium EN-EL15C batteries that worked fine with both my Z6 II and Z7 II. But, they do not currently work with my Z8. If I remember correctly, third party batteries didn't work with the Z6, Z7, Z6 II and Z7 II on their original firmware. I can't remember exactly which firmware update it was, but eventually, third party batteries started to work, like these from BM Premium. So, I hope that in the near future, these will also work in my Z8. They have the exact same specs for mAh, voltage and Whours, so there is no other reason that they can't work. I do have three (3) Nikon original EN-EL15C batteries, but I just hope that the other six aren't useless, now that I traded in my Z6 II and Z7II after getting my Z8.

I also tried this, and out of my 3 available En-EL15 batteries 2 did not work in the Z8. Original Nikon En-EL15 batteries that came with D800 and D750 cameras. Both show battery age as 0 (new) in D750 for example. While my AYRST brand third party batteries (and the EN-EL15b that came with my Z6) work as intended.

Thanks, same effect on my Z8 AND on Zf. I have 5 EN-EL 15. All don't work

Just to let you know I got 2 qty EN-EL15C Watson brand to use in my Z8 even though it said they would work with the Z8 on the B&H website - well they did not work I got that screen saying this as soon as I placed the battery in without even turning it on ( this battery is unable to provide data to the camera & cannot be used. For safety, choose a battery designated for use in this camera.) So, for now, it looks to be propriety Nikon batteries only. I hope this helps others not to make the same mistake I did.

The Z8 will also not work with ANY EN-EL15c battery made by someone else.

can only use nikon battery's you have to use nikon brand only that why they made it. so third party battery's do not break the camera or cause issue of over heating.

Are any of these batteries 3rd Party ones?
