I was looking for extra batteries for my Sony a6400 and watched a comparison showing 4 different battery brands competing in which K&F Concept was the winner for longevity, so I decided to purchase them. The proof is in the pudding is all I have to say, these batteries have been with me for over a year and still hold up great as they did when I first got them and they can easily be placed in the charging dock for easy transport. And for the price, you cannot beat these!

I was looking for batteries for my Sony 6000a and found this. It was reasonably priced so I bought it. Charger works great for my Sony battery. However the K&F Concept batteries it came with didn't even hold a charge. I contacted customer service and they got back to me saying they will be sending me new batteries. So I'll update this review to let you folks know if I got the new batteries and if they work.

It is compact, it has two batteries and it is cheaper than the Sony one, the durability is badly done because I have just started

Works amazing. Fits my Sony A7iii with no issues. They work just like the original Sony batteries. Love these and love that they come with their own charging station. I highly recommend these to anyone.

Doesn't last as long as the original(not to far either) but still very good value for the money. I would recommend

Very light and compact. Not the fastest charger, but benefits from charging two batteries at once.

I charged the batteries 1 month ago
When first used, they showed 99%.
So no discharge in the meantime.
During a photo shoot with -1 degrees they withstood the shock well.
4 batteries for about 700 photos. (2 Sony+2 in the kit)
I did not check the difference in discharge according to the brands but with respect to my use it is really a good choice.
Now to see in time.

After one year and a few months of use, the batteries work well, up to 30% of battery life remaining, then they are empty all at once, so be careful because over time they lose their discharging powers.
I also noticed that it took longer to charge.
While my 2 Sony batteries have no problems currently.
So I will go ahead and buy two Sony batteries and keep my 2 batteries as backup
October 2021
Well that's it they no longer hold a charge
Drain quickly and go to 0 to 30%
I will keep the charger which is practical and recommend a Sony battery.
They did the job anyway but my Sonys are still top notch.

Really good replacement for the original sony batteries for Sony a series cameras. I tested them and they are even better than the original ones. They lasted longar than the original ones and oh how I love the slim double charger, AMAZING!
I reccomend totally worth it!
