As you are making a purchase decision, we suggest that you take the time to read some NP-BG1 Battery reviews in order to see what other consumers have to say about the product. Here are some user reviews to help you make your shopping decision:

I'm using this battery on a Sony Cybershot camera and have been extremely pleased. I'm carrying the camera on my belt each day and I'm finding this battery stays charged for weeks. Granted, I don't use the camera all the time but will, periodically, pull the camera out to snap a shot or two or take a short video of something. This battery just keeps going and going. It also recharges in about 4 to 6 hours (depending on how low it is).

I would recommend this to anyone. I bought an extra one simply so I could have an extra battery. For times that I know I'll probably use the camera a lot, I take the extra battery in my pocket (in it's plastic case). Then if I need it during the day, there it is.

We bought this as a second battery for the Sony W50 digital camera. These batteries, in this camera, last a LONG time. Having a spare allows us to keep one in the external charger and swap quickly when needed. It is an original Sony product so fits and works perfectly.

Just an excellent deal! The LiON battery lasts for sooooo many pictures, but once it's getting low on power - picture taking is over. Don't miss another shot - it's worth every darn penny - it comes with a plastic carry case to toss it in your pocket - NEVER put it in your pocket with coins or keys without the case!!! The battery terminals are exposed and they are all next to each other - easy to short out and wreck your battery.

This battery was ordered as a backup to the one which came with my new Sony digital camera. The first battery (just like this one) is doing so well that I am sure the quality of the battery is great. I looked long and hard in stores in my area for a duplicate battery and then looked at amazon.com. They had the battery and sent it right away. Good battery...good service from amazon! What more can one ask?

After buying the Sony DSC-W90 in Black and being used to digital cameras eating up batteries fast, I figured I should get an extra just in case. Then I started using the camera and quickly realized that I can get over 200 shots before needing to recharge the battery. So I really could have gotten by without an extra battery.
However, Being I do a lot of long rides on my motorcycle and there are times I need that extra power supply, its good that I have it with me. There is nothing worse than seeing that great shot only to discover your battery is dead. Not many things will anger you more than that. So now when I take off on those three or four day trips into the mountains on my motorcycle, I will never have to worry about finding a place to plug in my charger to charge my camera battery. So if you find yourself without the ability to recharge, its a great investment to buy an extra battery. So now that its all said and done, buying an extra battery for my camera was a good idea.

This battery is for my Sony DSC-W80 Digital Camera. I always like to have a spare battery, even though my DSC-W80 has fantastic battery life in general. Found this on Amazon at substantial savings from local retail stores.
