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

Great battery, holds a change.

very nice and works great

New Manufacture's Battery works great!

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.

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.

There are many, many options on Amazon for 3rd party, Sony compatible batteries. I’ve read reviews of many of them, there are many good and bad reviews. After driving myself crazy to save a few dollars on a 2nd battery for my camera, I just gave up and went with the original Sony battery. At the end, I figure why risk damaging my expensive camera to save a few dollars, not worth it. I’ll save money elsewhere. These lasts for years also, so it’s worth the price, in my opinion.

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.

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 !
