            LI-POLYMER BATTERY INTRODUCTION
            Li-Polymer Battery Characteristics 

            Nominal voltage: 3.7 V; 

            Working voltage: .75~4.2 V. 

            Highest energy density, both volumetric and gravimetric
            Long cycle life:300-500 cycles
            No memory effect
            Environmental friendship: Deleterious metals such as Hg, Cd, Pb are not contained.
            Light weight and small volume
            Over charge voltage/Over discharge voltage protection are needed, and the voltage protection is monitored by the outside circuit.
            Self discharge is about 6% (20℃,30 days after fully charged), and would increase as the temperature increases.
            Temperature range:
              Charge: 0-45 ℃
              Discharge: -20~60 ℃
              Storage: -20~45 ℃
