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

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.

Works as it should, as good as the original

I brought this battery as a spare for my NEX-5. I used it for the first time on a recent weekend away. With a full charge the battery took about 250 shots over 3 days and still showed 30% battery at the end of the weekend. This was consistent with the standard battery that came with the camera. The battery I received from Stark Tch was a genuine Sony EU product, in a sealed blister pack and contained the Sony hologram in the top left-hand corner below the W Series branding. I was a bit concerned that this might not be a legitimated product as it was nearly 50% cheaper then the price on other websites but this seems to be a genuine product. Although even at £[] these batteries aren't what I would call good value.

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.

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

works well

I bought this battery believing it to be a genuine Sony product but it is not. An examination of the batteries label will review this. It seems to work fine on my a55 but fails to operate the NEX7. Disappointed in not spotting this earlier.

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!

NEX-5のために電池を2個持っておくほうが安心だなと思い、新品は高かったので非常に良いという状態の電池を買わせていただきました。 見た目もすごく状態が良く、電池の状態もむしろ既に持っているやつよりも良好でした！ 本当にいい買い物ができました！ありがとうございました！ (このレビューを参考にされる方へ、電池の容量は個体差があります。ご了承ください)

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.

Got original product.
