Test Equipment
(1) Dimension Measuring Instrument
The dimension measurement shall be implemented by instruments with accuracy no less than 0.01 mm.
(2) Voltmeter
Class with national standard or more sensitive class with inner impedance not less than 10 KΩ/V.
(3) Ammeter
Class with national standard or more sensitive class. Total external resistance including ammeter and wire is less than 0.01 Ω.
(4) Impedance Meter
Impedance shall be measured by an AC impedance method (AC 1 kHz LCR meter).
Standard Test Condition
Tests should be conducted with new batteries within one month after shipment from our factory, and the cells shall not be cycled more than five times before the test. Unless otherwise defined, tests and measurements shall be done under a temperature of 25±3℃ and relative humidity of 60±25%.
Standard Charge
0.2C = 402 mA
Full charge condition: At 25±3℃, charge with constant current 0.2C and constant voltage 4.2V until the charge current drops below 0.02C.
Charging time is approximately 6.5 hours.
