NP-FZ100 Battery Charger Set for Sony Alpha A7 III, A7R III (A7R3), A9, a6600, a7R IV, Alpha a9 II (2-Pack, Micro USB Port, 2280mAH)
SKU: KF28.0005
The batteries come about 2/3 charged and that is what is displayed on the original Sony charger.
The included K&F charger is very basic and has just a red / green indicator light, no status level for the batteries which I would have liked to find here. From that perspective, I am not a fan of this charger, I am not able to check the battery level with it.
The batteries specs (2280mAh / Voltage: 7.4V / WH: 16.8Wh) differ slightly from the original Sony FP-Z100 batteries (2280mAh / Voltage: 7.2V / WH: 16.4Wh) -- I would have liked to see the exact same specs.
The camera (with a firmware 2.0 update) recognized the battery and its charge status is displayed on the screen.
Even with the slightly different specs, the power and endurance seem like the original batteries. I cannot offer longevity observations due to a lack of long-time use.

I have been impressed with K&F products in general and this one is no exception. The charging station takes two forms of USB cable and has easy to see indicator lights. The charging takes the same amount of time as the OEM. The batteries operate the same as the OEM batteries. They check-out in my Sony A7r. I have included a picture comparing the two batteries front and back. The batteries appear to be manufactured well with crisp plastic molding and good contacts.

Purchased this product before I went away to Poland for a car show - these batteries last forever! They really are long lasting and the charger is brilliant, good indicator as to what charge percentage the batteries are at and is really easy to use, takes micro USB and USB C I believe (sorry if I'm wrong) a must have for your Sony camera kit!

The benefits of extra batteries is a must, but not at the price original ones cost!, these are the perfect alternatives, not only can they hold their charge longer than most, the adapter for dual charging, not only works on these but all Fz100 batteries, plus the added bonus of not triggering the Sony software for being third party items, definitely recommend, worth the money 100%

Very well packaged, arrived quickly, batteries pre-charged. Inserting the batteries into the charging cradle: a perfect fit, no play, no loose connections, no rubbing against the charging cradle, camera battery compartment, or vertical grip. USB-C charging cable length: 100 cm – perfectly adequate, flexible sheathing. Battery performance: no noticeable difference compared to the original. Excellent! Can be confidently recommended!
