Commonly seen portable electronic devices are Cellular Phones, Media Players, Digital Cameras, Digital Camcorders, Handheld GPS units, Digital Readers and PDAs. With the emerging technologies that are available today, portable electronic designers are trying to integrate more features into thinner and smaller form-factors while maximizing the battery life. Batteries are the main power source for portable electronic devices, and selecting a right battery system for a unique application is one of the important factors in the portable electronic design process. It involves selecting a battery chemistry and charge management control circuitry. The battery life indicates the length a product can be used under portable mode. Longer battery life can simply make a portable device standout in the market automatically. This can usually be achieved by reducing system power consumption and implementing an advanced battery technology.
