LI-POLYMER BATTERY INTRODUCTIONLi-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.
Charge: 0-45 ℃
Discharge: -20~60 ℃
Storage: -20~45 ℃
