Sony is again the company to look for with great products. I have experience with the Sony DSLR camers and the previous battery, (FM55), which was a great battery to use. I was loving the length of time I got from the battery but this one goes even stronger. This newer battery blows the lid off the amount of pictures. Once I could get around 900 shots now I can get about 1500 shots depending on flash usage and setup. If you need a battery with the stamina to keep pace with your picture taking this is it. It's even backwards compatible with the older Alpha 100 but the 100 battery will not work in the Alpha 700.

Sony has really increased the battery life with the newer infolithium batteries they offer. I use them with my A700 and various lenses. I can usually get a good 4 hours of continuous shooting out of them. That's powering the camera, lense motors, auto focus...etc.

Very good battery life. I was able to photograph an entire 6 to 7 hour Wedding without changing the battery once. I bought two of these batteries, but probably only needed to buy one because the life is better than I thought. Oh well, it's better to have too many batteries than too little...Also, this battery definitely lasts longer than the original battery that came with my Sony A-100.

The battery has excellent life and allows one to take more than 500 shots in a day. I took arround 500 shots and the battery was around 35%, which meant I could have taken another 100 more!!

As this is the brand-name battery that fits the Sony Alpha 100-200-300 (etc.) family of digital SLRs, it makes sense to buy the one produced by the maker of the camera. It holds a charge for a very decent time, but for a traveler, it is always advisable to have an extra battery, just in case.
