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.

Just finished putting this battery to the test and it is totally compatible with my Sony a35 camera. The battery life is superb and of course very easy to install. This was great value for money as other places I looked at were charging nearly £10 more.

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.

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.

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

This is so much better than another aftermarket brand that I purchased from Amazon. That didn't last half as long (in fact about a quarter) as this Sony one. Not really saving here.

One star short as communication with Sony charger is not accurate.

Niks beter dan het origineel natuurlijk. Wat prijziger dan de 3rd party accu’s maar ik geef dat er met plezier aan uit

Battery lasts in accordance with expectation and camera specs. Original brand product price is higher than the replacement, but given the cost of camera it is irrelevant.

Muito bom

I bought this product as a substitue for the one shown on the infomercial that is playing on TV every day now. My main concern was if the 2 sets of outlets would fold all the way to the left or right so that plugs could be connected from the side. Every picture I could find only has them turned 45 degrees and never the full 90. I've happy to report that the do turn turn the full 90 degrees and with surge protection built in, it is exactly the product I was looking for.

使用中の持ちも良く充電も遅くは無いので本物だと思います。 価格の変動が大きくて、私が買った時より800円も（セールではなく）安い時があり、焦らずに1カ月以上ぐらいは価格の見極めをしてから買えばよかったなとちょっと後悔しています。
