Electricity is a key element to modern life and without its benefits; our quality of life would be significantly different. Many portable, domestic appliances such as digital cameras rely on battery cells as a source of electricity.

The modern camera is an incredible invention which allows us to capture priceless snapshots and moments of our lives which we can then review and cherish at our leisure.

Cameras range in price and in quality, measured by megapixels. Megapixels determine the clarity of the photograph taken: the higher the megapixel rate, the clearer the photograph and so, the better the camera.

In addition, the better the camera, the more tasks it will be able to carry out and subsequently, the more battery life the camera will require. For example, if a camera has movie-shooting and voice-recording capabilities, this will involve a larger drain on the battery when this function is used. This will consequently affect the all-important number of photographs a camera can take before running out of power. The last thing you want to happen is for your camera to run out of power when you need it most. There are many different types of digital camera batteries available on the market, but sometimes it is quite difficult to decide which one is best for you.

The majority of cameras come with a standard battery, however, there are many kinds of camera batteries available to us today as an additional purchase. These include lithium, alkaline and nickel-metal hydride (NiMH) batteries along with many others. Each battery has its own advantages and disadvantages which make them suitable to particular uses more than others.

Usually, a lithium battery can be an expensive option but it is well-suited for digital cameras. In general, disposable lithium batteries have a much longer lifespan than their alkaline counterparts (sometimes as much as seven times more) and in many cases, it can also improve the speed that your camera functions at.

For this reason, many electrical and camera stores will recommend them. In addition, lithium batteries are readily available throughout the country, meaning you can stock up on them easily when running low. However, it is important that lithium batteries are disposed of properly as they have toxic properties and can be harmful to the environment.

Nickel-metal hydrides (NiMH) are rechargeable batteries which can save you a lot of money in the long run. The beauty of NiMH batteries is that they have a long lifespan and can be recharged whenever it suits you. Unlike lithium batteries, NiMHs are much more environmentally friendly as they are non-toxic and do not have any special disposable requirements.
