6. Q: If I want to test Lithium Polymer Battery, what testing requirements there are?
A: (1)Battery test environment:
,,,,Relative humidity: 60± 20% RH;
,,,,Atmospheric pressure: 86~106 KPa.
(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 meter accuracy no less than 0.5 ℃;
Impedance instrumentation requirements--Measuring impedance should by sinusoidal alternating (1 KHZ) test.
7. Q: What is full charged?
A: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 0.2 C for continuous discharge, when the voltage drops to discharge cut-off voltage 3.0V discharge is terminated, shall be full discharged.
9. Q: If your specification can not meet my requirements, can you design and build my battery?
A: Of course. We will design and build your own products according to your special requests.
10.Q: What is minimal capacity?
,,,,,A:,The capacity means the discharge capacity of the cell, which is measured with discharge current
of 0.2C with 3.0V cut-off voltage after the standard charge.
11.Q: What is typical capacity?
,,,,,A:,The capacity means the average discharge capacity of the cell, which is measured with discharge
current of 0.2C with 3.0V cut-off voltage after the standard charge at 23±2℃ environment
12.Q: What is retention capability?
,,,,,,A:,After full charging, storing the battery 28 days with 20 ± 5°C condition , and then staying 1 hours with
discharge current of 0.2C till 3.0V cut-off voltage.
13.Q: What is standard charge?
,,,,,A:,Charging the cell initially with constant current at 0.2C and then with constant voltage at 4.2V till charge current declines to 0.02C.
