You can buy with complete peace of mind, in addition to quality items at reasonable prices, they have exceptional after-sales service.

was very impressed with the set. The batteries feel no worse than the original Sony batteries. And the charger isn't bad either, as it has two charging ports. You always need...

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.

Batteries charge quickly and to our complete satisfaction. Excellent value for money. Delivery is fast and reliable. I'd be happy to use them again.

As a photographer, you always need batteries for your cameras. This was a quick, easy and reliable way take it all my batteries charged.

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.

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.

I have used it since January. Not many times, but whenever I go out and batteries need to be recharged. I never had issues and if I had a problem I asked the K&F Concept and they helped me quickly. Very professional. For me, it works almost as perfectly as the original Sony battery. Tbh, I don't see any difference and I am happy with the product!

Good battery life, about 30% less than an OEM sony battery but less than half the cost so pretty worth it in my book.

I recently purchased the K&F Concept NP-FZ100 Battery and Dual Slot Charger Set for my Sony A9, and I couldn’t be more satisfied with my decision. As a photographer who often shoots for extended periods, having reliable and long-lasting batteries is crucial. This set delivers on all fronts including traveling.

Battery Performance:
The 2280mAH capacity ensures that I have ample power to last through long shoots without constantly worrying about running out of juice. I’ve found these batteries to be just as reliable as the original Sony ones, if not better. They hold a charge well and provide consistent power output all while charging fast

Dual Slot Charger:
The dual slot charger is a game-changer. Being able to charge two batteries simultaneously saves a lot of time and hassle, especially when preparing for a big shoot. The charger is compact, easy to use, and the LED indicators clearly show the charging status of each battery.

Value for Money:
Considering the quality and performance, this set offers excellent value for money. It’s a cost-effective alternative to the original Sony batteries and charger, without compromising on quality.
