DSTE® 2X NP-FW50 Replacement Li-ion Battery for Sony Alpha 7 7R 7R II 7S a7R a7S a7R II a5000 a5100 a6000 a6300 NEX-7 SLT-A37 DSC-RX10 DSC-RX10 II III 7SM2 ILCE-7R 7S QX1 5100 6000 Digital Camera

This really is alternative battery for my power grasping A7r! Previous non-original alternative 2200mAh batteries were complete joke lasting maybe 15-20% of original Sony 1020mAh battery. I can't tell yet if these last what they claim... but they sure last the same or even better as original battery. I also noticed that both my original Sony battery and DSTE battery tend to restore some of their power while camera off. None of that happened with those other 2200mAh cheapos, they were loosing power while on and off.It seems these DSTE batteries are very usable even if they don't mach all numbers written on them or in the ad (these batteries are not 3.7V!). In addition a good charger like Watson Duo or Sony would be great upgrade also, can't wait to see how they perform together over time. For a high drain device like Sony A7R they seem to work fine and I do recommend them based on my experience.EDIT: 03/03/2018Now 3,5 years later few batteries finally gave up and two of them bloated up. Actually they are still keeping enough charge for my needs but they are just unsafe at this point plus they were getting stuck in my camera because of their bloated state (my camera has tight battery compartment)All together, their performance dropped to 500-600maH level max, while original battery maintained better capacity over 3 years. Looking back, the original battery still produced more clicks than this battery. Once a while I used a good charger that gave me exact current capacity readings.Only setback is that they get bloated, which may lead to getting stuck or even destroying your precious camera. I suggest not to use them longer than 1-1.5 years under heavy usage. But I still would get them as a backup and still recommend them for a daily work. Basically any li-po battery has breaking point when they just die, short out or swell up. Keep an eye out!

Work great for my Sony cameras. I lost one of the original batteries that came with my camera and I like to have one always charged and on hand so went looking for one to replace it and came across these. Have been using these for months now and can say so far no issues at all the performance is just as good as the original Sony ones just without the hefty price tag. These charge up just fine in my Sony chargers and now I am never without a battery back up. Great price for a wonderful product!

It is always important to have more batteries than you think you will need. This is my second set that I bought for my NEX3 camera. I cannot explain how much you always need just a couple extra, charged batteries available when you're doing an all day shoot.No, these don't maintain charge as well as their original counterparts. You're looking at (on average) about a 70% capacity comparison. This number is just a typical reference number, and just what I found by my shooting.But on the bonus, you basically can get a 2 for the price of 1, when you buy these. So if you're not too upset about having to carry around a few extra batteries AND you can get an improved 40% of battery life, versus the single battery.

I have bought several of these batteries. They are double the life of the Sony batteries that come with the a6500. They work great and last much longer. While no battery for these a6000 series of cameras will never last long, these work really well. Let's be real, Sony needs to come up with better batteries for these altogether. But these have worked as a really good replacement. If I have to have a lot of batteries, I will choose these.

I purchased these for my sony NEX5R and was all excited that I could get a pair of replacement batteries for my sony camera that uses proprietary accessories. Well the batteries did not work. The batteries are advertised to work in the Nex5R camera, but when I brought them to a full charge and put them into my camera, the screen came on for about 2 or 3 seconds, then it went to a black screen and the message said that the batteries were not compatible with the device, and the camera shut down. I am currently in the process of returning the batteries, and going to order some from Sony instead.

No complaints, just as good as the Sony one!UPDATE!!! Just now looking at my records and it charged me TWICE! Also it's complicated to contact them about this so all in all they get one star. True the batteries are good, but they freakin double charged me! I mean wtf?!UPDATE: bumping it up to three stars. I had them for about a year before they died. So I'm counting that a win for the price. I'm ordering two more right now

I've used Sony cameras that use these batteries for more than 6 years and have bought 4 batteries total from this company. No problems with any of them and performance was almost as good as the original Sony batteries. I even have one from the first set I bought almost 6 years ago that still takes a charge and lasts for about 140 photos. When new, I'd get about 250-300 shots from the batteries, which is pretty good for the cameras I use.

I bought these bad boys 7 months ago for my Sony Alpha 5000. Surprisingly, these bad boys still work and charge just fine. I haven't had any issues with them yet. They actually last longer than the factory battery I have for my Sony Alpha 5000. Good bang for your buck!

Yep, they work really well! I took my camera on a long hike with a zoom lens attached and didn't need to change the battery. Awesome! I wish I had 'em sooner!
