I bought these batteries when I bought my digital camera. I had heard that digital cameras are hard on batteries. Fortunately, I stumbled upon these in the same shopping trip.
I have used these batteries almost exclusively in my digital camera. I roughly estimate that these batteries last between 100 and 120 pictures on my Fuji camera. It is important to note that I never use the flash on the camera. If you use the flash often, it will reduce your battery life considerably, but this is true with any battery.
I have had these batteries for around 3 years, and they have been through many charge cycles and show no sign of dying. They are as strong as ever. Three years ago I may have purchased my last set of AA batteries that I will ever need to buy...
At $9.99 for a set of four, these batteries are a necessity if you use a lot of batteries.
In a review of the charger, I talked briefly about the batteries as well. If you buy these batteries, you will want the fantastic matching charger to go with them.
Buy this charger. The charger plugs right into the wall (and it sits on the wall), out of the way. It is compact in size and easy to store.
