I've used a Wasabi battery on my Nikon D850 for years, rotating between it and the OEM battery. It charges perfectly on Nikon's charger, and functions flawlessly in my D850. So, when I recently purchased the new Nikon Z9, I ordered another Wasabi battery for it. So far, it also works flawlessly, and I expect it to have the same long life as my other one. I can't tell any difference in the construction of the Wasabi batteries, nor any differences in their performance when compared to the OEM battery.-----As an update to this review, I want to mention Wasabi Power's superb customer support and the backing they provide for their products. One of my Nikon Z9 batteries failed after a year, and would no longer hold a charge. I emailed Wasabi Power's customer support over a weekend, and had a return email the next business day apologizing for the battery's failure and providing me with a copy of the order for a new replacement battery being sent immediately to me at no charge. This is the type of high quality business practice that used to be prevalent, but unfortunately it is the exception now. Wasabi Power has my highest recommendation for product quality and support.

I bought this as a backup battery for my Z9. I've had it for about two years now and no problems.

I was nervous about getting a 3rd party battery for my Nikon Z9 and didn't really need one as the original battery life is very very good and lasts a whole day shooting.However, I feel I owe it to my clients and subjects to have spares, just in case, but the Nikon versions are very expensive.This Wasabi mid-price replacement had good reviews , and I've used Wasabi for my other cameras so decided to give it a go. There are other lower cost replacements that I did not try.The Z9 recognized the battery on firmware 5.0 and I just updated to firmware 5.10 and it is still recognized so this will make a good spare to have just in case. Recommended.

These work well in Nikon Z 9 and Z 8 cameras. They may not quite equal the Nikon batteries, but they are better value. One battery usually lasts a day. Even in colder climates like Antarctica two last a whole day.

Works well for a back up in my Z9. Perfect fit for camera and charger. It does not last as long as the Nikon battery but it was enough to complete the day after the first battery was drained. Good deal for the price.I would recommend

OEM battery at a third the price of Nikon. Works with charger, recognized by camera. We'll see what happens in a year. Bought 3 year extended warranty just in case. Genuine Nikon battery from pawn shop didn't last a year. For Nikon Z9.

This was ok for the price. But it doesn’t hold the charge as long as the reg Nikon battery for it

Unfortunately, this battery claim to work with Nikon Z9, but in fact, it will not work with Nikon Z9. You insert the battery in the camera, and get a following message: "This battery is unable to provide data to the camera and cannot be used. For safety, choose a battery designated for use in this camera." Not sure why is this battery still being offered for sale. Thank you
