NP-FW50

Great battery, holds a change.

very nice and works great

Worked great in my sony camera.

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.

Good

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.

First and foremost, I used to work for "Sony Seattle Premium Outlet" before it leases was bought out by Ambercombie & Fitch. I work there for two years, I was in charge of the camera department hence I know everything about still camera batteries and video batteries for every make and model of camera. This battery is 100% the real deal. Its the same as the old Japanese built W series battery but now made in China. The reason for this is the battery used to cost $80.00 but the switch to a Chinese manufacturing shaves off $20.00. Also, the technology has vastly improved in the past few years thanks to the switch to a more uniform slightly slimmer design and YES this battery will work with your old W series charger that came with your camera. MOST importantly, take the battery out of the package and give it a complete full charge BEFORE you use it in a camera. Doing this will help to set the internal InfoChip to give you an accurate percentage reading of your battery power level. As for other Sony batteries out there. How to find an exact replacement for your old battery is simple. Etched or Printed onto the battery itself is a letter this indicates what battery is compatible with your product. For Example: W - Most Older Sony Still Cameras Nex and Alpha Series Z - Is the grandson and replacement for the W series battery, (WILL NOT WORK WITH OLDER CAMERAS THAT USE W BATTERIES) V - Is the uninformed standard for ALL Video Cameras (However the L series exist, but that's mainly used as replacements for OLD Handycams and external recording devices) M - Is used for large body full frame still cameras and broadcast field monitors. I hope this guide has been useful in helping clear up the confusion, on the legitimacy of this product.

I purchased these Sony brand NP-FW50 Lithium Ion batteries for my Sony DSC-10 (3) through Amazon at a better than local retail prices. These Sony batteries actually fit and lock into the battery compartment. I've recently purchased Kastar, Arche, and Bonacell NP-FW50 batteries (not through Amazon) and none of these batteries fit. They're all 2-3 mm too long to fit securely in the battery compartment so the camera wouldn't operate. Some of these same non-Sony brand batteries are also offered through Amazon and the price is attractive. Buyer Beware! Very pleased with the Sony brand batteries.

Price is a little pricey.

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.

We looked on line for a spare battery for our new camera, although the prices varied from each seller, some batteries were not the Sony make, although they tried to pass off a such, we decided to pay the extra money and take a chance with this seller, and we were not disappointed the battery arrived in good time well packaged and more important fits the camera as good as the original one and does not "rattle around" as some customers reported with a cheaper substitute. worth the money, thanks.

I do not like paying this kind of money for batteries, but based on multiple after market brands I have used original brand names do appear to hold charges longer, not only while being stored but during use.

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 !
