The batteries came half charged so I used the charger overnight to charge them to 100%. I then left both batteries for a few days before testing them with my Sony camera. Both batteries showed a charge of 100%.
One of my earlier third party NP FW batteries had a habit of slowly draining at about 1% per day when not in use and the camera was not in use, while another set completely failed within a year of use. This seems to hold the charge well for the time being. If I see problems I will update here.
As mentioned in the title of my review, the charger can be conveniently connected via a typical USB connector as well as a newer format (USB-C). The lights correctly indicate whether the battery is charged or not, and other brands of NP-FW50 batteries can be used.
Overall very good quality and no problems so far.

These work as advertised. They show up as “NH” batteries in an R5, so they unlock the power features including USB charging in the case. The charger also works well but only uses conventional power even when connected to a PD power supply. So don't expect fast loading.

I have a lot of generic batteries and some fit well and some don't. Some were DOA and others were the last of my original Canon batteries. So far these feel like a winner. They charge quickly and hold a good charge.

I use the battery on my Nikon D850 during a dive. I shoot 67 pictures with the camera turned on for 50 minute and the battery still reports 100% charge level. It seems to be of very good quality.
I am happy so far and recommend this product.

Best non Nikon batteries I've bought in the last 5-7 years. More expensive than others but charge lasts far longer than the selection of cheaper ones I've previously bought.

Using K&F Concept, it was easy to find the right product for my Nikon. The product offered is a cut above the competition – especially the capacity of the battery. Combined with a speedy delivery, I do not believe it can be beaten!

I got these as backup batteries for when I travel in rather remote areas of south America, these are very good, almost as good as the original. They charge up in the same time and hold their charge well, very good purchase.
