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

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.

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.

These worked great for my Nikon D750 , I will probably buy another set

The charger works very well, not fast but solid, it has both a USB C port and a Mini USB. The C port is a real plus. The batteries have held up to all day several hundred photo shoots so far so good.

The is a great value for the money if you own a Nikon Camera: I have owned several Nikon Cameras and one of the biggest issues I have always had is the charger going bad! This charger was one of the best replacements I have every purchased!

Quality: The build quality is pretty good: The plastic feel is somewhat on the light weight side, but it feels sturdy enough to endure constant transport and on the go use!

Performance: The charging performance is okay compared to the original Nikon Charger. This charger takes about 90 minutes to 2 hours to fully charge both batteries! The Original Nikon Charger took about an hour to fully charge. Not a deal breaker for me.

Battery Life: The battery life is really good for these to be after market batteries! I was able to get through two separate photo shoots without having to recharge either battery. That is pretty impressive during a 4 hour shoot!

Great option for aftermarket Nikon Charger.

These normally are expensive but this charger set pairs great with our nice camera. I like having extra chargers so we are never out of battery when it really counts.

Any photographer knows the first rule of cameras: the battery will run down just when you need it most. So extra batteries are a must, especially when using DSLRs to capture video. I get about 30 minutes of reliable recording time from each battery, so I keep half a dozen charged for any given event.

This collection of two batteries comes with a charger where the two included batteries can be charged simultaneously. That is important. It powers from a USB connection - super convenient for almost any venue and cars where you already have your USB adaptor in place.

The charger has red and green LEDs for each battery to indicate when a battery is fully charged. Super reasonably priced for getting both the batteries and the charger!

These gave about the performance I expected. So a good choice!
