Almost all digital cameras that have a rechargeable battery can charged using a power adaptor that comes with the camera, along with the manufacturer's specifications for the types of batteries that can be used with this charger. Another way to charge the battery would be through a universal serial bus cable that is linked from your computer to the camera. This draws up power from the power supply in the computer and then converts into the power requirement of your camera. This is also the same cable that allows you to link up with the computer so you can download pictures to and from the camera, possibly storing them in an internal memory or a removable memory card.

Most modern cameras today use lithium ion powered battery cells. Before, the common ones used were either Nickel Cadmium (NiCad) or Metal Hydride Batteries. Unlike the old type of battery cells, the lithium ion cells are very light and, surprisingly, pack more punch. These batteries have no memory, unlike the old NiCad cells that you need to drain out totally before you can recharge them. If you do not do this, the next charging will recognize the last point level before you started. This results in lower battery power and life. The other nice thing about lithium ion batteries is because they consume very little power. This allows you to shelf your battery longer once not in use. It is a very efficient type of fuel cell and is why it is being used in a lot of digital devices today.

The lithium ion cell works the same way as any battery, consisting of an anode and the cathode. During the charging state, the lithium ion flows toward the anode; when discharging, it moves toward the cathode. Depending on the manufacturers' claim, these types of batteries are rated by voltage and by milliampere-hour (mAh). This type of battery cell is very stable and lasts quite a long time.

If you want to know more about the specifications of your battery, you can consult the manual of your digital device or get in touch with your vendor. If you want to know more about battery cells concerning your camera, you can get more information on the Internet about your digital camera power supply
