Sony NP-FW50 Lithium-Ion 1020mAh Rechargeable Battery

Great battery, holds a change.

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

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

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.

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.

Works great! Good 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.
