K&F CONCEPT 2100mAh EN-EL15 EN-EL15C Battery and Dual Slot Charger for Nikon ZR Z8 Battery Compatible with Nikon Z8 Zf Z7 Z7ii Z6 Z6ii D7500 D750 D850 D780 1V1 Camera

Works reliably for me with Z6iii and Zf. I’ve bought other 3rd party batteries that either didn’t work for my Z6iii, or failed after less than 2 months.

K&F concept batteries and chargers always work with my older Nikon, and now proven with my new Nikon Z7II and Z8. I was a bit worried as I heard the Z8 can be picky about non-Nikon batteries, but they work like a charm! Last a good long time ago - I used them over the holidays on a couple of short shoots. No issues. Charging is easy. Because the charger is flat, it packs easily in the base of my small Molle bag. Highly recommend.

I have not usedcthem yet. The camera recognizes them. Will report after a trial shoot with them

Batterys work well

This is an update to a previous review. Previously, I rated the product 1 star because I couldn't get the batteries to charge and the charger appeared to be defective. After a couple of weeks (I was out of the country) the seller was able to reach me and offer to replace the product or receive a gift card (in addition to the refund I had already received thru Amazon). I chose to have the batteries and charger replaced since I have 4 camera bodies I used all the time and fresh batteries always come handy. The new batteries and charger arrived promptly overnight. After fully charging both batteries without any issues with the charger, I have been using the batteries non-stop on my cameras for three days now. The battery life appears to be just as my Nikon EN-EL15 batteries, delivering about the same amount of time and shots as the OEM Nikon batteries. They have performed well as the principal battery in-camera and as the primary and secondary batteries in the camera grips. The cameras (Nikon D7000, 7200, 500 & 750) have NOT given any error code because of the aftermarket batteries and the performance seems to be at/near the same level of the Nikon batteries. I am very pleased with the purchase so far and will continue to monitor performance in a qualitative basis as time progresses. Really happy with the customer support offered and their genuine desire and insistence to make things right. This K&F product is the third one I purchased and all have met my expectations at very reasonable cost.

They keep my d850 chooching along. LOL

Batteries can't hold a charge. Once they're fully charged, I put one in the camera and it's already down to 80%. Put the other one in? Same problem. Put the first one back in and now it reads 28% full. For a K&F product, this was a big swing and miss.

I bought this charger and 2 batteries to charge my Nikon Z 7. the batteries keep charge as well as the Nikon Brand. A USB-C cable is included for powering the charger .K&F makes good quality products . Happy with my purchase.
