1 Excellent battery life even in cold weather
This is the battery I compare all other digital camera batteries to. I've owned many digital cameras from Nikon, Konica Minolta and Sony and the Sony NP-FM50 lasts the longest. I used this battery in my F707 on a climb of Denali in Alaska. At the 20,320 summit on a chilly evening my digital camera was the only one that still functioned out of three in our group thanks to the Sony NP-FM50! I own two batteries for my F707 but even on week-long backpacking trips I really only use one battery and I use the LCD on the camera for all pictures.
2 Very Good Battery For The DSC-F717!
This makes the fourth NPFM50 battery I have bought for the Sony DSC-F717. The first battery konked out after a time without knowing why exactly, but the two after that have worked flawlessly and for a great length of time. I expect that the fourth battery (which hasn't arrived yet) will do just as well. This battery has great longevity in between charges and is well-made. I take away one star because of the original battery konking out.
3 interchangeable battery
If you own other sony products then you know the value of this battery. If your thinking about buying a sony product then concider getting one with this battery. Lasts a very long time and recharges quickly. The best part is that I have never had to dispose of one from it not charging.
4 Great Battery Concept
This is Sony's workhorse battery. It is not cheap but it recharges very quickly and I've got one I've had in use for 4 years now and it still charges up 110 min of power.
5 Sony makes long lasting batreries
I have two different Sony camera's. The life on Sony batteries is quiet good; however for long days an extra battery is a must.
