K&F ConceptNP-FZ100 Battery and Three Slot Charger, 3-Pack Replacement Battery for Sony A7iii, A7iv, A7C, FX3, FX30, A9, A6600, A6700, ZV-E1, ZV-E10ii, Alpha 9, A9S, A7R III, A7R IV, A7R V, 2280mAh

These work perfectly in my Sony A7RV. A great value, and the 3-at-a-time charger is very handy. Highly recommend this.

Batteries are long lasting!! Definitely great value for your money!

These batteries work seamless in my new A7RV with the firmware updated to V 3.04. I felt the batteries didn't last as long as the Sony but might be how I use the camera.

Awesome batteries! I’ve been buying this companies products for a few years now and the batteries are just as good as everything else they make. These last just as long as my Sony barriers. The charger is fast and I’ve purchased more than one of these sets. I’ve never gotten the “battery not supported, cannot guarantee safety of this device” message from these that you get with some cheaper aftermarket batteries.

Batteries don’t last that long. But it’s convenient having all 3 of them. The charger charges them up fairly quickly with the USB-C plug.

i have multiple sets of these because you can never have enough batteries. they work flawlessly in my FX3 and both of my ZV-E1's

Fast deliveryExcellent qualityBest price

These batteries were great in my Sony camera. We all know how the Sony cameras like to eat through batteries. These hold up well
