3.1 Standard Test Conditions
Test should be conducted with new batteries within one week after shipment from our factory and the batteries shall not be cycled more than five times before the test. Unless otherwise specified, test and measurement shall be done under temperature of 25±3℃ 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.
3.1 Measuring Instrument or Apparatus
3.2.1 Dimension Measuring Instrument
The dimension measurement shall be implemented by instruments with equal or more precision scale of 0.01mm.
3.2.2 Voltmeter
Standard class specified in the national standard or more sensitive class having inner impedance more than 10k/V
3.2.3 Ammeter
Standard class specified in the national standard or more sensitive class. Total external resistance including ammeter and wire is less than 0.01.
3.2.4 Impedance Meter
Impedance shall be measured by a sinusoidal alternating current method (1kHz LCR meter).
3.3 Standard Charge/Discharge
3.3.1 Standard Charge : 0.2 C5
Charging at 0.2 C5 constant current until the battery reaches 14.6V. The battery shall then be charged at constant voltage of 14.6V while tapering the charge current. Charging shall be terminated when the current has tapered to 0.05 C5A. Charge time is approx 7.0 hours, The battery shall demonstrate no permanent degradation when charged between 0 ºC and 55 ºC.
3.3.2 Standard Discharge : 0.2 C5
Battery shall be discharged at a constant current of 0.2 C5 to 10.0V @ 25º ± 3C
3.3.3 If no otherwise specified, the rest time between charging and discharging is 30min.
3.4 Appearance
There shall be no such defect as crack, rust, leakage, which may adversely affect commercial value of battery.
