Sony NP-FW50 Lithium-Ion 1020mAh Rechargeable Battery

Great batteries. Loved that they are OEM so I bought 2 more. Just wish they weren't so expensive. They fit my A6400 perfectly and now I cant tell which was the original.

Works great! Good battery.

The great mystery is why anyone would conclude that this battery is not a genuine Sony battery. It could not be more obvious that it is. I can't rule out the possibility that Amazon somehow bought a batch of counterfeit batteries at some point and was selling them unknowingly. That is possible I supposed, but it is not particularly likely, and even if it happened, it did not continue for very long. The packaging is exactly the same as the packaging you see for this battery anywhere else, to include the retail shelf at BB. And there aren't any visible differences between this battery and the battery than came with my NEX-7. As for the price markdown, it is apparent that Sony permits on-line retailers to sell this battery at a discounted price, that Sony specifies, because there are many on-line retailers who sell this battery, and they all sell it for the same price. The only way that could occur is if Sony tells them that they can sell it at a discount, and tells them the specific amount at which they are permitted to sell it. The fact that this is clearly taking place is further compelling evidence that this is a genuine Sony battery. And the package has the special holographic security strip, that shows the Sony logo only if you hold it at the required angle relative to the light. There just isn't any reason for anyone to think that this is not the real deal. It could hardly be any more obvious that it is the real deal. But, if you prefer, you can go buy it at BB instead and pay twice as much for it.

Took forever to charge but it's doing well so far. I think it will hold up better than the cheaper options.

This is a replacement for the original Sony battery. If you liked the original, you will be pleased with this replacement.

These genuine Sony batteries are worth the extra cost as they last much longer than the cheap knockoffs in my experience. If you are packing for a trip and trying to lighten your load, knowing you can take 2 of these and get the same life as 4-5 others is good to know. Plus, they're reliable longer term.That said, I did receive one and it refused to charge - both in my genuine sony wall charger as well as a knock-off USB.It seems the issue could be that some of these may come so completely drained they won't come to life enough to accept a charge. The instructions even note that it could take a few tries. Well, 10 tries and I ended up returning it. The replacement worked perfectly.May be a fluke, and it's possible it was fine if it could just get a minimal base charge. (I was tempted to try, but didn't really have time to mess with it, plus, the replacement came in a day.)Otherwise I will say I'm happy with the two of these I have compared to the knock-offs. These really are better and longer lasting.
