A digital camera, as opposed to a film
or videotape camera, uses an electronic sensor to transform
images (or video) into electronic data. Modern digital cameras
are typically multifunctional and the same device can take
photographs, video, and/or sound.
In 2005, digital cameras are starting to
push traditional film cameras out of many markets. Shrinking
device sizes have recently allowed miniaturized digital cameras
to be included in multifunctional devices, such as cell phones
and PDAs.
Digital Cameras are a high drain electrical device and due to the nature of cameras requiring high current bursts over short periods of time (when taking a picture and using the flash) it is vital that the correct battery is used to ensure effective use of the camera. Some digital cameras come with a custom battery pack designed specifically for that camera; in this case there is no real choice of battery, but many digital cameras run using standard AA size batteries and this is where the choice of battery becomes important.
Many people use standard Alkaline AA batteries and find that they do not last very long before failing, this is because Alkaline batteries were not designed for use in high drain pules applications such as digital cameras. Despite poor performance in the camera, the expense of buying replacement batteries frequently can really add up, a better option when it comes to batteries for digital cameras is Rechargeable NiMh batteries.
NiMh batteries are designed for use in high drain applications such as digital cameras and with capacities as high as 2700mAh, the number of shots you can get in between charges can be up to 500. Couple this with the fact that NiMh batteries can be recharged between 500 and 1000 times, the savings that can be made over a year compared with using disposable batteries can be as high as £650. A saving for your pocket as well as the environment reducing the amount of waste caused by throwing away disposable batteries.
