NP-FW50 Efortek Replacement Battery Charger Set for Sony A6000, A6500, A6300, A7, A7II, A7SII, A7S, A7S2, A7R, A7R2, A7RII, A55, A5100, RX10, RX10II

Worked well for a few years until I recently went to remove one from my Sony a7ii, it had swollen to the point that I had to pry it out. Carefully. Luckily it hadn't started leaking yet and when I checked the 2nd one it was swollen also, charger still works fine so 2 stars but I'll be buying Sony batteries from now on. Why save a few bucks only to risk a camera that cost over a grand?

Both of these batteries discharge on their own when not in use. I charged my Sony battery and the two new batteries and after 2-3 weeks the new batteries were at 86% each and my original Sony battery was still at 100%. I find this too annoying.As a follow up to my review, I notified the seller of the problem I was having and their response was: "Since the original battery the cell is made in Japan and ours made in China, there will be difference as you can see the big price difference."So there you have it, you make the decision.

These batteries work as well as the Sony battery my A6000 came with. The charger is very quick and charges all 3 of my batteries (these two and my original) very quickly. The light on the charger works (a lot of times in my experience, the lights on these things quit quickly). I haven't used the car charger part of European adapter. I just plug the box straight into the wall. I am so happy I bought this. It was the best price I could find for the 2 batteries and charger. At the speed in which it charges, you don't really need a charger that charges both batteries at once. This one is perfect.

Although it works, at least one of the batteries has been very difficult to remove from the battery compartment. I eventually can get it to dislodge but this method is simply not acceptable to use on a regular basis. I have taken that battery out of my camera bag. I will probably stick with the Sony brand ones that I have and take this as a lesson learned.

The batteries are great! The charger is not; the batteries don't properly fit, and after you think you've charged it because the light is green, it's really still a dead battery. After several tries, I finally just threw the charger away. However, the batteries are awesome!

This is much needed addition to the Sony a6000. These Sony camera's are awesome, but one of their major problems is a notorious for a short battery life. Make sure you buy extra batteries, and having a charger is necessary the only way to charge these is with a charger or through the camera (not recommended). So far I am impressed with the Li - ion battery quality, as good as original Sony battery.

These batteries work just like the Sony but are so much cheaper so you can buy a bunch of them if you are not able to charge batteries for while (like backpacking). I have owned four of them.

Works well. But you do need to press the battery quite hard in order for it to snap on the charger, but I personally feel like this is more secure and safe.
