6.2.4
Over-discharge Protection
Characteristics
Under the temperature of 23±2
℃
., after discharging the battery with
0.2C to 3.00V, then connect the load with 30Ω and discharge for 24h.
It is required the battery should be no leakage, fire, smoking and
explosion during the test processes.
6.2.5
Short-circuit Protection
Characteristics
Under the temperature of 23±2
℃
., after full-charging the battery with
0.2C, then make the battery’s anode and cathode short-circuit for 1h
(the connecting resistance is smaller than 100mΩ), then cut the anode
and cathode, after the battery momentary charge by 0.2C current
，
the
voltage should come back to 3.7V, and there should be no leakage,
deformation, smoking and explosion during the test processes.
6.2.6
Constant Humidity and
Temperature
Characteristics
Under the temperature of 23±2
℃
., after charging the battery with
0.2C, then put the battery into the constant temperature and humidity
oven with 40±2
℃
and 90
～
95% for 48h, the battery should be no
obvious deformation, leakage, rust, smoking and explosion. After
testing take out the battery then rest for 2h under the temperature of
23±2
℃
, discharge with 0.2C to 3.00V. The discharge time is required
≥72min.
6.2.7
Drop Test
Under the temperature of 23±2
℃
., after full-charging the battery with
0.2C, then drop it freely from 1 meter height onto the hard board
which 18~20mm thick (6 times each of X, Y, Z with positive and
negative directions).The battery should be no smoking and explosion.
6.3 Standard charge
(0.2C=520mAh) Full charge condition: Constant current 0.2C, Constant voltage 4.2V for 6.5 hours in all
at23±2
℃
.
6.4 Standard test condition
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 temperature of 23±2
℃
and relative humidity of 45~75%.
6.5 Test equipment
a.Dimension Measuring Instrument
The dimension measurement shall be implemented by instruments with accuracy no less than 0.01mm.
b.Voltmeter
Class with national standard or more sensitive class with inner impedance not less than 10 KΩ/V.
c.Ammeter
Class with national standard or more sensitive class. Total external resistance including ammeter and wire is less
than 0.01Ω.
