A
camcorder is a portable electronic device for recording video live-motion video/audio signals onto a storage device. It's a combination of camera and recorder in one unit. Camcorders are self-contained camera recorder units which allow recording and ususally play back, of live events. A lithium battery is generally used as an electric power source for camcorder since the battery is easy to carry and is easy to mount on the electronic device. Lithium battery comprises lithium metal as a cathode active material and manganese dioxide as an anode active material. The lithium battery also includes an electrolyte which includes an inorganic electrolyte dissolved in a nonaqueous solvent containing propylene carbonate. The lithium battery has a low self-discharge and a high energy density. Camcorder battery packs are generally limited to use with a single brand of camcorder.
