NP-FW50

Great battery, holds a change.

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

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

Well, it's a battery. And it's very good at being one, as it is identical to the that came with my camera. Though, I did find the price a bit too high for it being just a battery, even when factoring in that it's original.

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.
