Summary: Bought this as a replacement battery for my Sony Cybershot. It works perfectly and was about 1/5 the price of the Sony namebrand battery. In fact from Sony the shipping on the battery amounted to almost the total price of this one!
Summary: A good price on the real Sony battery. Delivery was fast. Plugged it in, charged it, and now my camera is back to having the superb battery life it started with. Only complaint - it is pricey everywhere.
Summary: My wife and I have used this battery for over 2 years in our Sony PC100. We are casual users with kids - so we take 200 to 250 photos/videos a month. The NP-FR1 battery lasted us 2 years before it went dead. Considering the grueling conditions we put it through, we were really pleased with the consistency and longevity of the battery. We've used the Sony W-1, which uses AA batteries, and it can't keep up with the battery life of the NP-FR1.
Summary: I received my battery within a week of ordering. I used the battery while on a trip to Philmont Scout Ranch and took about 400 pictures over a two week period without having to recharge it. I was very pleased with the battery.
Summary: This battery holds its charge well over 24 hours and has strong performanace while in the camera as well. I do rapid shots at times and it still manages to keep up. Just remember, don't keep it in your camera for more then 48 hours....
