K&F Concept 1600mAh EN-EL25 Battery and Set with LCD Dual Slot Charger, 2 Pack Replacement Batteries for Nikon Z30 Z50 ZFC Camera
SKU: KF28.0031
I have a Nikon Z50 that uses the EN-EL25 – I used to charge the battery in the camera, but now I’ve got a charger I can keep plugged in and just pop the battery in when I need. I really wish the design of this had the indicator lights on the other side of the battery. When you put the batteries in, they block the view of the indicator assuming the cord is at the back. It works, it charges, but I wish I didn’t have to stand over it to see the light just to see if it’s done charging. Using the batteries that come with it, they seem to work as well as any of the OEM ones.

I tested these batteries with my Nikon Z50. I found they do not last as long as the original OEM battery when recording video and also the maximum video clip length I could record was reduced by about half, probably due to overheating.
I was able to record 100 minutes of 1080p 60Hz video with these batteries. That is about half of the 208 minutes I recorded using the OEM battery. Also, the OEM battery was able to record 30 minute clips (which is the max my camera supports) without stopping whereas with these batteries recording halted after anywhere from 10 to 20 minutes. I am assuming the shortened clips was due to overheating as I was not watching the camera when the recordings stopped. Note, this was indoors in a 70 degree environment, not outside in the blazing heat.
As far as the charger, I found it took 2 1/2 hours to fully charge a depleted battery. Note also that the charger does not come with an adapter so you will have to supply your own. The charger is also able to charge the OEM battery.
These batteries are an inexpensive way to have backup power for your camera but I probably wouldn't want them as my primary battery due to their limited life.

I am using this type of batteries for quite a long time and this set is very practical because it has two batteries and also dual slot charger which is a big plus because it allows me to charge both of them at the same time.
The charger has a compact size and I like that it has USB type c port and like this I don't have to carry with me any additional cables and I have noticed that a charges both batteries in roughly 2 hours which means that I can constantly use my camera.
Because usually I record video using my camera, one battery lasts for around 30 minutes which is still very practical and I find this set to be valuable because I can easily swap the batteries around and while one of them is in use, the other one is charging.
Also I have noticed that during the charging process, the batteries don't warm up that much and so far I am satisfied with their performance so I consider this to be a good set for my camera.

For $70, you get 2 batteries and a charger and USB-C charging cable. The battery charger has both
USB-C and micro USB ports for extra flexibility and a useful 4 bar charging status indicator. The battery
claims to have extra capacity compared to OEM battery but that remains to be seen. Many 3rd party
batteries claim extra capacity without merit. Still, if these batteries function anything close to the OEM
batteries, then this is a really good deal price-wise.

The battery holds its charge well, offering peace of mind during important shoots. It’s become an essential part of my gear, ensuring I’m always ready to capture the moment without worrying about running out of power.

Second time getting a K&F Concept battery for my cameras. This time I picked up EN-EL15C battery. No issues with my Nikon Z8, Z6 or Z7. Works just fine without any error messages. Cheaper option when buying extra batteries for the cameras. You are able to charge them with your regular charger or via USB-C which comes in handy when you already have several other products that are using USB-C like your cell phone & headphone. I am able to use this battery without issues when shooting 20 fps on my Nikon Z8. If you are in the market for something that cost less and works just as good as the OEM, this is one does it.
