A:(1)battery test environment；
Temperature:23±2℃;
Relative humidity:60±20%RH;
Atmospheric pressure:86~106Kpa.
(2)Measuring instrumentation requirements
Voltage instrumentation requirements--Measuring the voltage meter accuracy no less than 0.5 magnitude;
Current instrumentation requirements--Measuring the current meter accuracy no less than 0.5 magnitude;
Time instrumentation requirements--Measuring the time meter accuracy no less than 0.1%;
Temperature instrumentation requirements--Measuring the temperature mater accuracy no less than 0.5℃
Impedance instrumentation requirement--Measuring impedance should by sinusoidal alternating(1 KHZ)test.
7.Q:What is full charged?
A:With charging voltage 4.2v,current 0.2C continued to charge the battery pack ,when charging current drops to 0.02C charging is terminated,shall be full charged.
8.Q:What is full discharged?
A :Standard discharge current 0.2C for continuous discharge is terminated,shall be full discharged.
