Sony NP-FW50 Rechargeable Lithium-Ion Battery Pack for Select Alpha Mirrorless and NEX Series Digital Cameras – Long-Lasting Power

Always best to have a spare battery for the camera when travelling. Arrived perfectly and on time.

I have been using Sony cameras NEX and A7n and A7rn that take this battery for many years now. Put off by the price of the OEM units I researched and bought recommended 3rd party batteries. I tested these for capacity and only one brand had equivalent, or better capacity to the Sonys, this was DSTE. Satisfied, I bought several DSTE batteries. In early use the DSTEs were as good as my Sonys, but after a few months I noticed that they began to sef-discharge rapidly and gradually lost capacity. I still have the Sony batteries that came with my cameras, they still have good capacity and hold charge well on the shelf. ALL of the 3rd party batteries I have tried are long gone, they simply do not last, and these were brands recommended by users on the net. I only buy OEM Sony batteries now, and not one of these has let me down so far (touches wood). In this case the old adage "if you buy cheap, you buy twice" really does apply.

Hands down, the best option for your Sony camera. Whatever you think of Sony’s battery choices (the np-fw50 does seem like an under-performer for serious shooting/video and the more recent higher capacity upgrades Sony has made on newer cameras, should have been made much sooner in my opinion), If you are looking for one of these, this is the one to get. -reliability -charge retention -build quality -piece of mind -lifespan You could get several cheaper batteries, but in my experience- none of them touch the Sony ones on the above points. It’s just down to you whether you can stomach Sony’s pricing.

works well

Not much more to say, these are great and last long. Considering how expensive cameras can be I wouldn't want to risk putting a 3party battery in it!

This battery has been behaving oddly. Took a few charges to start showing a charge above 78% and seems to discharge faster than the one that came with the camera. May be old stock? At the price I cant be bothered to test it more formally

ITS SONY IT WILL BE GOOD

Great battery, it is a feuine Sony battery and as expected performs very well. It does seem to be expensive for a battery but the price on amazon is cheaper that others I have seen. Really happy with it regardless, definitely worth buying original batteries instead of other brands
