Datasheet

17．Free falling:
(Drop)
 Store the cell or battery more than 24
hours after standard charge, following a
drop test from 450mm (17.717 inches ) on
to a hard-wood board in a vertical axis 2
times on each of 2 mutually perpendicular
axes,
 The subsequent fluctuation of open
circuit voltage and internal
impedance shall be less than 0.02
V and 5mΩ respectively, and the
cell or battery shall not be
externally deformed and no
leakage of electrolyte in liquid
form shall be observed.。
18．Short-circuit
testing
 to store it for 1 hour after standard
charged, and to make positive and
negative electrode short-circuit with a
wire with the section 0.75mm
2
min and
shortest length, the short-circuit time is 1
hour
 It shall not explode during or at the
end of a 1 hour short-circuit test.
However, leakage of electrolyte,
external deformation or outer
sleeve cracking is permitted.。
19. Safety Valve
Performance
(Over dis-
charging)
 to be discharged with 1C mA for 5 hours
 The safety valve must start
normally , battery without
breakage;Leakage, distortion and
outer package breakage are
allowed
20. Safety Valve
Performance
(over charging)
 to be charged with 1C mA for 5 hours
 No explosion, but leakage,
distortion and out package
breakage are allowed
21.To discharge at
low temperature
 to be stored for 24 hours at 0±2, and
discharged at 0.2C mA at 0±2。
 discharge duration shall exceed 3
hour and 30 min。
22.To discharge at
high temperature
 to be stored for 24 hours at 70±2, and
discharged at 0.2C mA at 70±2。
 discharge duration shall exceed 3
hour and 30 min。
5. The transportation and storage
5.1 Transportation
In the transportation process the battery should maintain at clean, dry, and the well ventilated
environment, and prevents the fierce vibration, the impact or the extrusion, prevents to be exposed to the
sun and rain. Battery could be transported by automobile, train, steamboat ,airplane and other
transportation vehicle .
5.2 Storage
5.2.1 Battery must be stored at -20  ~ +35 , (It is best at 15 ~ +25 ) and put in the clean, dry and
ventilated place with relative humidity 85% max.. It must be kept away from corrodent substance,
fire hazard and heat resource.
5.2.2 Storage placement way
The packed battery in a carton stack less than 5 layers, to guarantee that between the cell box has the
good air circulation condition, please maintain between the carton above 5~10 cm distance, which
prevents the safety incident caused by a pile of agglomeration to heat .
