Batteries for Digital Cameras
A digital camera needs to have some type of power source because it's an electronic device. Batteries are the easiest way for you to power your digital camera. You can connect some cameras into an AC outlet but this is an impractical way for you to use the camera if you're not in a studio setting.
The camera LDC display, as well as the camera flash, requires a battery to power them. A sure way to drain the batteries is by leaving the display on when you're not using the camera. If you don't have any extra batteries you risk losing that once in a lifetime picture.
The majority of digital cameras will use AA batteries. You can buy AA batteries almost anywhere at a very low cost. However, when you use non-rechargeable batteries you spend a lot more money on batteries while at the same time harming the environment. The ideal solution is to have a few sets of rechargeable batteries available.
Digital cameras need batteries that have a high energy level through the energy cycle because they are considered "high drain". NiMH (Nickel Metal Hybride) rechargeable batteries are best for digital cameras. The NiMH battery is inexpensive and will keep your camera charged longer than other types of batteries. As well, these batteries are composed of non-toxic materials and are safe for the environment.
Some digital cameras come with lithium-ion batteries which are supplied by the manufacturer. While these batteries cost more than NiMH batteries they also keep their charge almost double the time. As well, a lithium-ion battery will keep its charge while it's in storage and the power will drain at a predicable rate so that you can determine how much power your camera still has.
If nothing else is available you can use alkaline batteries for your digital camera, however they are the least desirable since their power will be gone after you take a few photos. Alkaline batteries that are rechargeable are just as bad since their power will be gone after two or three pictures.
You should get up to 100 shots with a fully charged NiMH battery if you are careful about how you use your camera. If you use the camera flash, leave the LCD on between photos, or do a lot of focusing and zooming the number of shots per battery life will be reduced.
