Test Conditions



1. Standard Test Conditions

Test should be conducted with new batteries within one week after shipment from our factory and the cell shall not be cyded more than five times before the test. Unless otherwise specified,test and measurement shall be done under temperature of 20±5℃ and relative humidity of 45~48%.if it is judged that the test results are not affected by such conditions,the tests may be conducted at temperature 15~30℃ and humidity 25-85%R.H.




  • Measuring Instrument or Apparatus

    • Dimension Measuring Insturment





The dimension measurement shall be implemented by instruments with equal or more precision scale of 0.01mm.



2.  Voltager

Standard class specified in the national standard or more sensitive class having inner impedance more than 10kΩ/V.




  • Ammeter



Standard class specified in the national standard or more sensitive class.Total extermal resistance including ammeter and wire is less than 0.01Ω.




  • Impedance Meter



Impedance shall be measured by a sinusidal alternating current method(1kHz LCR meter)




  • Standard Charge/Discharge

    • Standard charge:Test procedure and its criteria are referred as follows:

      0.2C5A= Charging shall consist of charging at a 0.5 C5A constant current rate until the cell reaches 14.6V. The cell shall then be charged at constant voltage 0f 14.6 volts while tapreing the charge current Charging shall be terminated when the charging current has tapreed to 0.02 C5A.Charge time:Approx 6.0h,The cell shall demonstrate no permanent degradation when charged between 0℃ and 45℃.

    • Standard Discharge: 0.2 C5A= Cells shall be discharged at a constant current of 0.2 C5A to 10.0 volts @20℃±5℃.

    • If no otherwise specified,the rest time between Charge and Discharge amount to 30min.
