9．Electrical Characteristics 电气特性
9.1 Battery charge/discharge 电池组充/放电
9.1.1 Full charged definition 充饱定义
With charging voltage 4.2V, current 900mAh (0.5C) continued to charge the battery pack, when
charging current drops to 36mA (0.02C) charging is terminated, shall be full charged.
以充电电压4.2V，电流900mA (0.5 C) 对电池持续充电，当充电电流下降至36mA (0.02 C) 时
充电被终止，即为充饱。
9.1.2 Full discharged definition 放空定义
Standard discharge current360mA (0.2 C) for continuous discharge, when the voltage
drops to discharge cut-off voltage 3.0V discharge is terminated, shall be full discharged.
以标准放电电流 360mA (0.2 C) 进行持续放电，当电压降至放电截止电压 3.0V 时放电被终止，即为放
空。
9.2 standard charge 标准充电
