4
with precision less than 0.01 mm.
2Multi-meter
Precision of multi-meter not less than0.25%internal resistance larger than
1MΩ
3Loaded Resistance
Loaded resistance should include resistance of external circuit and the
tolerance has to be less than 0.5%.
4.3 Test Method
1 Appearance
By visual observation.
(2 Dimensions
Dimensions are measured according to 4.21. When measuring the total
height of battery, protector should be mounted on one or two sides of the
measuring contact to avoid battery short-circuit.
3Open Voltage
Measure the battery according to the stipulated temperature of table 1 stored
for 4 hours or above and using mutli-meter at the same temperature and
should comply the requirements of 4.22.
4Loaded Voltage
Measure the battery according to the stipulated temperature of table 1 stored
for 4 hours or above and using mutli-meter at the same temperature and
should comply the requirements of 4.22,loaded resistance should
comply with the requirements of 4.23when circuit is closed and take
the reading within 0.8 seconds.
5Operating Life
Measure the battery according to the stipulated temperature of table 3 stored
for 4 hours or above and under the same temperature with loaded
resistance to discharge in table 3, continuously discharge to end voltage of
2.0V, the battery life will be the discharge time under the conditions of
continuously discharge.
6High temperature operating life
Measure the battery according to the stipulated temperature and storage time
of table 4. Then the battery is taken out and stored under the temperature
of 20±2 for 4 hours or above and then discharge continuously to end
voltage of 2.0V. This discharge time will be the high temperature operating
life.
7Leakage Property
Measure the battery according to the stipulated temperature, relative humidity
and storage time as listed in table 5. Then the battery is taken out and
stored under the temperature of 20±2 for 4 hours or above to conduct the
visual observation of leakage property.
8Leakage under over-discharge
Measure the battery according to the stipulated conditions as listed in table 6.
Then the battery is taken out and stored under the temperature of 20±2 for
4 hours or above to conduct the visual observation of leakage property.
