Standard Test Conditions:
Test should be conducted with new batteries within one week after shipment from our factory
and the cells shall not be cycled 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 45~85%.
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%RH.
Dimension Measuring Instrument:
The dimension measurement shall be implemented by instruments with equal or more
precision scale of 0.01mm.
Standard class specified in the national standard or more sensitive class.
Total external resistance including ammeter and wire is less than 0.01Ω.
Impedance shall be measured by a sinusoidal alternating current method(1kHz LCR meter).
Standard Charge :Test procedure and its criteria are referred as follows:
Charging shall consist of charging at a 0.5C5A constant current rate until the cell reaches 4.2V.
The cell shall then be charged at constant voltage of 4.2 volts while tapering the charge current.
Charging shall be terminated when the charging current has tapered to 0.01 C5A .
Charge time : Approx 4.0h,
The cell shall demonstrate no permanent degradation when charged between 0 ºC and 45 ºC.
Cells shall be discharged at a constant current of 0.2 C5A to 3.0 volts @ 20º ± 5C
If no otherwise specified, the rest time between Charge and Discharge amount to 30min.
There shall be no such defect as flaw, crack, rust, leakage, which may adversely affect
commercial value of battery.
