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.

After more than 50 charging cycles, absolutely problem-free and reliable in handling

To be honest, I dislike The En-EL14 batteries for Nikon cameras as much as i do the NP-Fw50 batteries for Sony. These batteries have always had terrible battery life in my use cases. So having multiple batteries was always a must, to ensure that i was never up a creek without a paddle when i needed it most.

K&F has always done a good job with their series of batteries. I have tested their batteries across multiple camera brands and i have never had any issues with any of them. The only thing that can be said is that these do not give you the full battery life that the OEM will offer but the reduced battery life to cost savings over the OEM is worth it in most cases for me.

I used these batteries in my Nikon D5600 and D3500. I noticed more of a difference in performance in my D5600 battery life when compared to OEM than with my D3500. I took both cameras out with me while i walked around getting shots of nature for the day. It was about 95 degrees that day so i expected the batteries to die much faster, which did not happen. The batteries held up well in the higher temps and gave me a sufficient amount of shots. In most cases, i would never take over 300 shots when birding or anything of that nature but did on both cameras just to better access the batteries.

The biggest area that i noticed a difference in was when i left the batteries fully charged in the camera bodies and coming back 2 days later to one at 52% and the other at 39% when i had never seen the at much of a power drain on my OEM batteries when i left them in the body. Not sure why that happened but i know now to never leave those batteries in the body if i want them fully charged and ready to go.

Overall these are good batteries that fall slightly short of the OEM. It is also hard to find new OEM batteries, so amongst the deep sea of third party batteries, these are some of the better ones i have used.

Very pleased with these batteries that works great in my aging Nikon D5100 DSLR that can be picky about aftermarket batteries.

Pleased that the charger accepts USB-C charging and has big clear red / green status leds for each battery.

I’ve tried a few products from K&F concept and have been impressed with them all.

5/5 recommended

Compatible batteries for Sony Alpha 6000 series camera. They work great and it is very convenient to have the external battery charger. Possibility to connect the charger with the supplied USB-C cable or micro-USB (not included). I am fully satisfied with the construction quality, compatibility (I have an alpha6100) and charging speed (I use a 2 amp wall charger). Perhaps they have a slightly shorter life than the original SONY batteries but I have not noticed the difference, plus with what an original battery costs at a little more than half the price you will have 2 and a dedicated charger.

This is a pretty decent set and a good price. Compared to the OEM, the batteries retain their charge well and charge quickly.

There is not a lot else to say about this set other than it is a good product at a good price if you need additional or replacement batteries or a charger.

For extended use with only short breaks, a second battery and external charger are essential. The lack of the required USB power adapter is easy to live with these days and doesn't represent a negative for me. You almost always have suitable power adapters for other devices in your household that you can easily use as a backup. It's good for the environment!

The charger does exactly what it's supposed to: charge two batteries simultaneously. It works very well; the indicator light makes it easy to check whether the battery is full or still charging. The charger can be connected to a power adapter or a computer via a USB port. Would I buy it again? Absolutely!

Bought with my first camera (SONY ZVE10), and frankly I didn't expect spare batteries to be so useful. They certainly don't last as long as my camera's original battery, but the fact that there are 2 of them more than makes up for this shorter lifespan, and the battery charging station is super practical, it also charges my Sony battery. Really a very good purchase especially considering the very affordable price!! I recommend :)

These batteries do a good job of powering my Nikon, they're easy to keep charged, with the included charger. They're priced fairly for lithium ion batteries. I'm glad I ordered them. If I run into any issues with them, I'll update the review.
