    Electronic Characteristics test and inspection:

    • 4.1

      Standard testing environment

Unless special stated, tests should be done within one month of delivery and the charging-recharging times is less than 5 times. The following is test conditions:

Ambient Temperature

250.5

Ambient Humidity

65 20%

    • 4.2

      The requirement of measure instrument

    • (1)

      The measure instrument is passed tested by qualified institute.

    • (2)

      The accuracy of the size instrument is not more than 0.01mm.

    • (3)

      The accuracy of multimeter is not less than 0.5%. while measure the voltage, the internal resistance mustn’t less than 10K.

    • (4)

      The principal of the internal resistance is 1KHz LCR, the accuracy is 0.2%.

    • (5)

      The internal resistance is changeable, it varies according to the temperature and the charging mode. And it is relevant to the PTC and the length and the Capacity of the drawing line.

    • (6)

      The current accuracy of the battery test system is more than ±0.1%, is obarically accuracy is ±0.5%, timer accuracy is less than ±0.1%.

    • (7)

      The accuracy of the temperature meter is less than ±0.5.

    • 4.3

      Visual inspection

Any visual inspection defects will affect the electronic characteristics, such as cracks, leakage, and flaw, are not inexistence. 4.4 Charge/Discharge Methods and Test Conditions
