Well, it's going really well. I don't know if the batteries will last as long as the original Sony batteries, but both the charger and the batteries are doing very well for now.

Cheap and good. Let them give them to the Sony people who now don't even give you a charger with the camera.

Well impeccable, we don't know why the battery was faulty, we talked and they solved in a matter of nothing the replacement at no cost. I recommend this seller, out of 10 we have no words the truth. Everything is perfect.

For anyone wondering, as of 14 April 2026, I tested those batteries with the latest firmware on these cameras, and both correctly report the battery percentage:
FX30 - Firmware version 6.01
a6700 - Firmware version 2.00
Here is the capacity comparison shooting 4K 50fps on the FX30, compared to a genuine Sony battery:
Genuine Sony battery: 1h 39m
K&F battery: 1h 31m
FX30 - Firmware version 6.01
a6700 - Firmware version 2.00
Here is the capacity comparison shooting 4K 50fps on the FX30, compared to a genuine Sony battery:
Genuine Sony battery: 1h 39m
K&F battery: 1h 31m
