4. BATTERY TESTING EQUIPMENT AND CONDITIONS
4.1. Appearance
There shall be no such defect as scratch, bur and other mechanical scratches, and the
connector should be no rust dirt. For the structure and dimensions, see the attached drawing
of the battery.
4.2. Measurement Apparatus
1. Dimension Measuring Instrument
The dimension measurement shall be implemented by instruments with an equal or more
precision scale of 0.01mm.
2. Voltmeter
The standard class specified in the national standard or more sensitive class has inner
impedance less than 10 KΩ/V.
3. Ammeter
Standard class specified in the national standard or more sensitive class. Total external
resistance, including ammeter and wire, is less than 0.01Ω.
4. Impedance Meter
Impedance shall be measured by a sinusoidal alternating current method(AC 1kHz LCR
meter).
4.3. Standard Test Condition
The test 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, test and measurement shall be done under a temperature of 23±2
℃
and relative
humidity of less 75%, air 86Kpa~106Kpa.
4.4. Rest Period
Unless otherwise defined, 30min, rest period after charge, 30min, rest period after discharge.
