Electronics / Batteries / Energizer Rechargable AA Batteries

I have been using the Energizer Rechargable AA batteries for almost one and a half years now for my digital camera. I am now on my second set. The first set lasted about a year. Since they come in a 4 pack, I always have two in my camera and two to keep on the charger. They take about eight hours to charge. The life of the battery in the camera really just depends on the amount of pictures I take. If I am out and about taking pictures all day, such as on vacation, they barely last throughout the day. Usually by late in the day they are starting to get low. If I just have them in the camera while at home and am only taking a few pictures here and there they can last several days, maybe even a few weeks. I am somewhat happy with them, but really wish they had the power to last throughout the entire day when I am visiting someplace that I want to take a lot of pictures.
