Sony NP-FW50 Lithium-Ion 1020mAh Rechargeable Battery

This battery fit perfectly in my camera. It last a long time and it’s perfect as a backup

Works as my other charger stopped working.

Lasts long time.

New Manufacture's Battery works great!

There is no argument on the longevity of a Sony vs cheap battery. If I have learned anything in my years, don't buy cheap stuff. My original Sony battery for my A6000 is still gong strong, but the LAST (#5, I write the number on them to rotate thru in usage) of the cheap batteries will no longer hold a charge. #4 is on the way out, and #2&3 are slowly catching up. Please, you spent all this money on a good camera, buy a good battery. Thanks.

9/23/12, revised from 1- to 4-star rating (should probably be only 3.5 to be nitpicking about it). From somewhere in Europe. I have now used both (original that came with the NEX-7 and the one from Amazon marketplace. I started out with using the Amazon unit. After like half the afternoon, the battery went kaput! I switched in the other one, and it seemed to fair much better, tho at the end of the day, it'd still be (almost) run. However, on using the original equipment unit, I paid much closer attention to usage, etc. I then noticed somehow that "perhaps" with the camera bouncing in my lap (hung from shoulder), I seemed to notice the LED display screen was on much more of the time. I then started to hold it, with it facing down, and it seemed to fare much better. Just a coincidence perhaps. Perhaps because of the bouncing, somehow the eye-level viewfinder was activated???? causing the drainage???? I did the same with the Amazon unit, and it seemed to do much, much better, tho not quite as close to that of the original, but perhaps both acceptable. Then, I started to notice that somehow it was in I think "VIDEO" mode, and a running clock was on display . I had to shut off the camera, turn it back on, the check I think the shooting mode, and got it back to SINGLE SHOT mode. I was clueless how that got triggered. It happened on this Europe swing (so far a week now) about 4 times now. I will have to talk to Sony, see what triggered it. I am clueless as to how it came about. PERHAPS that's why the battery got drained?????? I'm sure I will even update this mystery later. All digital point-and-shooters are power-hungry because of the LED screen, etc. So, one'd better have a backup for a full-day shooting session. I'd like to have a battery that would last me like 8 hrs. a day, but.... this ain't the case. Considering the situation, I revised the star rating as such. ------------------------------------------------------------------------------------------------------------------- Early Sept., 2-12. The more I researched, I decided on a genuine Sony battery for my new NEX-7. So I purchased 1 thru Amazon, of course. It looked good, except that I noticed the label at the back is not quite 100% as the one that came with the camera, slightly different. Anyhow, I am in Europe now, really field-testing both units. Last couple of days, I would start out with both batteries fully charged up. Each time, both batteries ran out on me after 2-3 hours on the street. It was never that I shot continuously. I'd shoot a few shots, then walk, then a few more. The screen would just go out after a little while. I checked, there's a 10 second after-shot review delay before it'd go out.... Mostly I walked around with it without turning it off; and, because it's a new toy, I was playing around with the menu setting here and there, playing with Scene/Mode/Aperture/Speed etc. Just today (9/14), I went on THE Royal Way around Warsaw, the best part of town. 4-5 hours later I think, one expired about 2 hrs. later, so I put the other in; 3-4 (altogether) hrs. later I think, both were dead. I would say for the last 2 outings, I couldn't have shot more than 30-40 shots total each day/time, with only a couple using the HDR mode (if that matters much at all), other than those, they're just point-and-shoot situations. Am I not using the battery correctly? Or is the NEX-7 really drains that badly? Anyone care to comment (on how to be scroogey and save juice), I'd appreciate. Otherwise, on a single day's outing, I'd need at least 3 batteries. That's RIDICULOUS I'd say. Since the new one purchased here from Amazon gives me similar usage, I wonder if it would warrant sending it back. I will pay closer attention in the next couple of days about usage, to see how bad it really is before deciding.

Factory battery. More expensive than the knock-offs, but I'm willing to pay more for the factory battery for a high dollar camera. No need to worry about failure with the original and consistent charge time and charge off time.

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.

I was amazed to get a Sony battery for less than £50! it seems to be just as good as a full priced new one! Charges quickly too. I'm not sure what makes it "used" as it looks like new, though wasn't in Sony packaging.

Price is a little pricey.

Worked great with my Sony Alpha a6100! lasts much longer than generic batteries. Yes, it’s expensive, but I needed something reliable for long aurora borealis sessions. I used two batteries for about 2 hours of burst shooting at -10°C, and they performed flawlessly. Totally worth it!

Aus langjähriger Erfahrung weiß ich, dass Sony original Akkus wesentlich leistungsstärker und langlebiger sind als die von Fremdanbietern. Man kann sie, um Geld zu sparen, oft auch getrost gebraucht kaufen. Der von anSanto gelieferte NP-FW50 war, wie versprochen, nahezu neuwertig. 19.90€ inklusive Versand mit Rückgaberecht (was ich selbstverständlich nicht in Anspruch genommen habe), sind ein wirklich faires Angebot, und ich bin froh, das hier auf dem amazon marketplace entdeckt zu haben. Ein Blick in die "Kleinanzeigen" verrät schnell, dass das anSanto-Angebot unschlagbar ist.

Lorsquez l'on compare la baterie d'origine Sony à des produits de sous-marque, on sait que ce produit est sensiblement plus cher mais on sait ausii pourquoi : il ne vous abandonne pas en pleine prise de vue alors que votre batterie de rechange est restée dans le sac dans la voiture ! Une bonne photo, ça n'a pas de prix !
