4、BRAND AND PACKAGING
Both OEM and ODM orders are welcome. Any specific design and packing requirements will
be accommodated as required.
5、TESTING
5.1 Initial test
Means the test begin in three months or less after production.
5.2 Test conditions for Samples
Unless otherwise specified, the test conditions for samples shall be, as a general rule, at the
temperature of 20±2℃ and the humidity of 65±20%.
5.3 Measuring instruments
5.3.1 Voltmeter
The accuracy of the voltmeter shall be within 0.005V for each 1.5V. The resistance of the measuring instrument
shall be at least 10 times the discharge resistance but with a minimum of 1 M ohms per volt of the scale.
5.3.2 Load resistance
The load resistance shall include all of the external circuit, and its allowance shall be within ±0.5%.
5.3.3 Caliper
The caliper shall be the one having precision of 0.02minimeters or the one having the same or superior
precision to this.
5.3.4 Electrical drying box: Tolerance shall be ±2℃ or below.
5.4 Test methods
5.4.1 Dimensions
Dimension shall be measured with instruments specified in subparagraph 5.3.3 above,
provided that either one or both side of such instruments shall be insulated in measuring
the overall height of the batteries.
5.4.2 Appearance Examination shall be carried out by visual inspection
5.4.3 Off-load Voltage
The specimen batteries shall be kept for 8 hours or longer at the ambient temperature
specified in 5.2, and than the voltage between both terminals shall be measured at the
same ambient temperature with a voltmeter as specified in subparagraph 5.3.1.
5.4.4 On-load voltage
The specimen batteries shall be kept for 8 hours or longer at the ambient temperature
specified in 5.2, and than the voltage between both terminals shall be measured with
a voltmeter as specified in subparagraph 5.3.1 while the specified load is connected
between both terminals at the same ambient temperature as specified above; provided
that the measured value shall be based on meter reading taken 0.8 seconds after the circuit
is closed.
5.5.5 Service life
Test specimen batteries shall be kept for 8 hours or longer at the ambient temperature
specified in 5.2, and shall then be continuously discharged at same ambient temperature
and through the specified load resistance. The discharge shall be continued until
the terminal voltage of 2.0V, and the time during which the terminal voltage has been
maintained equal to and above the discharge end-point voltage shall be taken as the
service life.
5.5.6 Service life at high-temperature storage
Test specimen batteries, after having been stored at the temperature and period specified
in 3.3, shall be kept for 12 hours or longer at ordinary temperature (20±2℃) and at ordinary
humidity (65±20%RH) and shall then be continuously discharged through the load
resistance 15KΩ at ambient temperature of 20±2℃. The discharge shall be continued
