     A: We accept USD, EUR, CAD, AUD,HKD, GBP, JPY, NZD, SGD, CHF, THB, etc

 

6. Q: If I want to test Lithium Polymer Battery, what testing requirements there are?

     A: (1)Battery test environment:

Temperature: 23±2℃;

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 

temperature, unit:mAh

 

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.
