On first attempt they don’t prompt the “battery not recognized” that some other 3rd party batteries do on my R6, so that’s promising. Whether they last as long as the OEM battery will remain to be seen. Not really sure in what situation I would need to use the USB-C port to charge these since I already have dual chargers, but maybe they would charge a little faster. I guess it’s nice to have in a pinch.

When you purchase a Canon EOS R5, R6, R7 (etc), it comes with a Canon LP-E6NH battery. The LP-E6NH looks identical to the older LP-E6 battery and these R series cameras can use them both, according to Canon.

But there is a practical difference (aside from the higher battery capacity of the newer battery): These Canon mirrorless cameras are capable of in-camera battery charging via the camera's USB-C port - but only if the battery is LP-E6NH. (This feature is convenient when traveling, for example. No worries even if you forget to bring a battery charger. You can charge a genuine Canon LP-E6NH inside the camera by connecting to a USB-C charger capable of PD (Power Delivery) rapid charging.)

Now, in the past I purchased a few generic "LP-E6NH" batteries from Amazon. But my EOS R7 would recognized them as "LP-E6" batteries. (So no in-camera charging option with them.)

To my pleasant surprise, with these K&F batteries, my EOS R7 camera recognizes them as "LP-E6NH". (See photo.) I also confirmed that the EOS R7 camera charged this K&F battery in-camera, via the camera's USB-C port, as expected. (Unlike the case with LP-E6 batteries from other sellers.)

These K&F batteries are equipped with a USB-C port on the battery itself. So you have two options for charging these: 1) Charging them inside the camera, or 2) outside, in both cases using a commonly available USB-C charger. (No need for a battery charger specific to LP-E6/E6NH.)

As far as the battery capacity/longevity, in my past experience non-OEM batteries never last as long as the genuine factory batteries. So I expect more of the same.

Still, at about half the price of a genuine Canon battery, these non-OEM may still be a decent value, especially for everyday, non-critical uses.

I may still decide to deduct star(s) for battery capacity after I have more experience using these K&F batteries. But so far they haven't given me any issues with my Canon EOS R7 mirrorless camera, for both still and video.

So for now I would like to give this product 5 stars.

Got these as backup batteries for my work Canon R5. So far they work great, the hardest part was fiinding a USB-C charger to charge them up. Comes with the cable but not the wall charger. These batteries also charged up on my third-party LP-E6NH duplex wall charger, so very convenient. It is also reccognized by my third-party battery grip, and read out levels correctly. This is a great battery for keeping in my pocket of my work vest for emergencies. It can also be charge from the USB cable on my car charger, another benefit. I also like the fact that it is a different color, very easy to tell at a glance which are Canon OEM and which are the K&F. When charging these, there is a little LCD at the top that turns from red (while charging) to green (cwhen completed). All in all, I glad I ordered these and hope to wear them out in my R5 system in the next few years!

A two-pack for less than what Canon charges for a single LP-E6NH battery. That's a great value and both batteries are recognized as LP-E6NH units in the battery grips of an 5DII and EOS R. Both batteries are delivered with 90% charge and are ready to go. Both have worked great in the limited amount of time I've used them. Slightly larger listed capacity than the OEM batteries but we shall see how that translates in real life scenarios. Will update if anything changes.

I've had the batteries a month now. Obviouslu can't comment on longevity and they might deteriorate faster than own brand canon batteries but they work flawlessly with my R7 and charger great through the regular battery's charger or through the usb plug built in which is very handy!

Works as it should and lasts for lots of shots over a time

Great price for a pair of batteries for the Canon R7 with the advantage of being able to use a phone charger or power-bank to recharge on the go. Longer lasting than standard batteries and able to be used in our Canon 80D as well

In the field these are versatile and are recognised by the camera.
Very pleased with these

I bought these because my original batteries were not keeping much charge, and because the normal chargers are pretty bulky.

Everything else I have charges using USB-C cables, so now I don't need to carry special chargers for my camera.

These batteries seem to have about the same performance as the original battery for my 90D, and they charge pretty quickly.

good fit for my Canon EOS 5D Mk4
so far so good they work I use them in a battery pack in pairs
