1
Temperature
Cycle
Store the battery for 48 hours at 75±2℃after standard
charge, then store the battery at -20℃ for 6 hours, and
at room temperature for 24 hours. Observe the
batteries’ appearance.
No leakage, No smoke,
No fire, No explosion.
2
Static Humidity
Put the battery at 40℃±5℃ and 95%RH chamber
for 48h, then get it out and store it for 2h at room
temperature. Observe the appearance and discharge
at 0.5C to 2.75V, then test the final capacity.
Discharge capacity
after storage is more
than 90% of rated
capacity. No obvious
outside damage, No
corrosion, No smoke,
No explosion
3
Vibration
Standard charge. Equip it to the vibration platform,
prepare the test equipment according to following
vibration frequency and relevant swing, doing
frequency sweeping from X, Y, Z three directions,
each from 10Hz to 55Hz for 30 minutes of
recycling, rating of which is 1oct/min:
A)vibration frequency:10Hz～30Hz
Displacement breadth (single swing): 0.38mm
B)vibration frequency:30Hz～55Hz
Displacement breadth (single swing): 0.19mm.
Observe the final state after scanning.
Residual Capacity≥90%
Rated Capacity
Voltage Decrease Rate
≤0.5%
No obvious outside
damage, No leakage, No
smoke, No explosion.
4
Normal Storage
Test the batteries’ initial state and capacity; store the
battery for 30 days after standard charge, test the final
state; Discharge at 0.5C to 2.75V, then test batteries’
residual capacity. Then after normal charge, discharge
at 0.5C to 2.75V, then test the batteries’ recovery
capacity，Three cycles are permitted for this test, If one
of the three cycles can reach the standard, it represents
the battery has reached the standard.
Residual Capacity≥90%
Initial Capacity
Recuperative
Capacity≥95% Initial
8. Standard Test Environment
Unless especially specified, all tests stated in this Product Specification are conducted at below condition:
Temperature: 25±2℃
Humidity: (65±20) % RH
9. Storage and Others
9.1 Long Time Storage
If the battery is stored for a long time (more than three months),the battery should be stored in dry and cool place.
The battery should be charged and discharged every there months. The batteries’ storage voltage should be 3.6~3.75V
and the battery should be stored in a condition as NO.8.
