I'm really happy with this battery set. Having spare batteries on hand is great, especially when I'm traveling and I don't know if I'll be recharging anytime soon. I love that these charge through USB, which makes it easier on the road if I do need to charge them.
So far they work just as well as my Nikon battery. I haven't done a shot count on them, but I'm sure they're fine. These batteries work in my Nikon charger, and vice versa for the Nikon batteries in this charger. You can tell they are well made and I've used other K&F Concept products before and have always liked the quality. Totally worth it!

Fast charger and good batteries. I go through a lot of batteries when taking product photos because the video output is usually on so I can see lighting changes through the lens. Having a fast charger and two extra spare batteries handy makes a big difference. The battery life seems as good as anything else I have, and so far they are working well. The charger is compact, too. Being able to charge two batteries at a time instead of one as in the Nikon charger is a major plus. Altogether, a great setup and a worthwhile addition to your gear.

Just bought a used A7RV and only came with the original battery. Purchased this as a second set, as I usually need at least 3 when I'm off shooting. Batteries charged up perfectly and the charger turns green when the reach a full charge. So far, life seems as good as my original Sony. Good purchase!

They work really good in my camera for being 3rd party. I will 100% be buying another set for just incase reasons.
Edit: So I definitely ordered another set and here's why.
No 3rd party battery warning, it gives me the battery percentage number all the way until the battery dies. I've tested it on all 4 of my K&F concept batteries in my Sony A7iv.
The best part is on a full charge in "basic" 4k mode you get 2 hours of continuous filming with the Sony battery ( $85 or so each) but these K&F batteries will get you 1 hr and 52 minutes each and you get 2 of these battery and a charger for $50. 10/10 I recommend!

I like that they came with a charger, and a charger that will charge 2 batteries at the same time, with a separate indicator for both batteries! The charger is flexible, it comes ready to use USBC, or Micro USB The batteries fit perfectly in the camera, are the same rated power as my original battery, 1050 MAH. Now with two spares, there should be no worries about running out of power! The D5100 is pretty good about not eating batteries, so this should easily handle a heavy shooting day! They certainly seem like a good quality product.

I bought this charger with the two batteries for three reasons. Firstly, the original Nikon batteries were too expensive for me, secondly, I wanted a lightweight solution as a charger for vacation and thirdly, I have always been very satisfied with the K&F products in terms of quality and price. Unfortunately, one of the two batteries died while I was on vacation. The support team not only replaced this battery, but also gave me a new charger and an additional battery!
This is more than exemplary and I will continue to use K&F products...

No issues what so ever. 1 charger and 2 batteries. It shows if it’s charged or not charged. Does exactly what I need it to do.

Got these to use with my Sony a7 and they held up great for an 8 hour wedding day doing video!

This kit includes a charger and two batteries that are perfectly compatible with the NIKON Z6 III, unlike another kit previously purchased on Amazon and whose batteries were not recognized by this device (error message and inability to use them).
The charger also allows you to charge the original NIKON EN-EL15c battery.
The only downside is that these batteries cannot be charged directly in the device, but this is really not a problem for their use.
Having just received it, no opinion yet on the autonomy of these compatible batteries compared to the original one.

I have both a D800 and a Z6 and these batteries work fine in both cameras. As a bonus, the original batteries also charge up fine too. In terms of longevity I think these batteries last longer than the original Nikon ones too. Highly recommended.
