Test Method and Condition Visual 目测 Caliper 游标卡尺 Scale 秤 CC/CV (Constant Current / Constant Voltage) As of shipment., Voltmeter 出货状态,伏特计 Impedance meter at 1kHz AC 1kHz 交流内阻仪 After fully charged， discharge at 0.2C current until the voltage reaches overdischarge voltage. 充满电后，0.2C 放电至截止电压 Charge: CC/CV， CC at 0.2C， CV at overcharge voltage， Cut-off Current: 0.05C. Discharge: 0.2C to overdischarge voltage. 0.2C 标准充电至最高电压，然后 0.2C 放 电至截止电压 After fully charged, store the Battery under the condition as No.4.4 for 30days, then measured the capacity with 0.2C till 2.1V 充满电后， 在 No.4.4 条件下贮存 30 天， 再以 0.2C 放电至截止电压所放出的容量。 After fully charged， maintain the cell at different temperature for 60 minutes， and then perform 0.2C discharge until the voltage reaches overdischarge voltage. 充满电后， 在以不同温度放 60 分钟，再 以 0.2C 放电至截止电压。
