I ordered two batteries (zwei) inside the box there is only one battery, although 2 are written on the package.
Update: the error was on the shipment made by Amazon, k&f support was super helpful and willing to send me the missing battery directly home.

Love these batteries, absolutely life changing. I no longer need to bring a battery charger when I travel and I can charge them with a power bank whilst I'm out and about. Their capacity is larger than the original Sony batteries so it's a no brainer! Confirmed they work with Sony a7IV and a7c

I have been using K&F batteries for professional photos and videos for about a year, with great satisfaction and peace of mind This 2600 mAh model exceeds those of the same brand in durability and reliability at a reasonable price

These batteries work great! I also love the USBC charge port very convenient to charge on the go in the car. These batteries last longer than an afternoon day to night Timelapse transmission. Can’t beat the price either.

Haven’t used these batteries enough to determine how long they will last, but they work fine in my A7iv. The USB-C port is great for charging.

Guys, if you are looking for a battery with higher performance than the originals, you know which to choose!
I was amazed at how long they lasted! Normally I have always used batteries from other competing brands and although they declare lifespans similar to the originals, they never reached a breakeven, but here the 2600mha are real and give you that extra peace of mind when you are out for events or anything else!
In addition, the extra bonus is the USB C connector that allows you to charge them with any charger, which is very convenient when you forget the original at home.

I ordered these batteries to use with my A7C during my vacation without a simple possibility of recharging them, I brought both and finally never exhausted the first in 1 week of vacation

Third party batteries usually over promise and under deliver by using bad cells or similar.
This kit has 2 batteries that claim 2600mAH compared to the stock 2280 mAH. I am not going to do a torture test or say which lasts longer. I will say however, I was not left wanting more life or felt like the K&F was cheating me by misrepresenting. This could even mean this battery is actually just 2280 and I would never know but it does last at least the same amount of time.
The added benefit of having the internal charging functionality is nice and a welcome addition but a few notes about it. The little orange trays that come with these batteries is a nice to have but it blocks the charging port. The charger being internal to the battery is a concern as it simply adds more components and more heat to an already tight package.
I would still buy this kit over the $80 Sony wants for ONE battery and no charger regardless of any concerns I have about longevity.

Maybe because they are new but the batteries are lasting long, the USB C makes it so much easy to charge on the go. I carry 3 of these with me to shoots and they last roughly an hour each on my Sony FX3
