Datasheet

Note：The data may be different from the above value，if the environmental
temperature is changed。
14．Cycle Life
 Based on clause 7.4.1.1, IEC61951-
2 2003。
 The charge-discharge cycles
shall exceed 500
times。
15．Humidity
 Standard charge and store for 14
days under the following storage
conditions： 33℃±3℃(91.4℉±
5.4℉) ，Relative humidity of 80%
±5%. (Salting is permitted).。
 No leakage of electrolyte in
liquid form shall be
observed。
16．Vibration
 Store the cell or battery more than
24 hours after standard charge,
following vibration tests over an
amplitude of 4 mm (0.1575 inches)
at a frequency of 16.7 Hz(1000
cycles per minute) and repeated
through any axes during 60mins。
 The subsequent fluctuation of
open circuit voltage and
internal impedance shall be
less than 0.02
V and 5 mΩ
respectively, and the cell or
battery shall not be externally
deformed and no leakage of
electrolyte in liquid form shall
be observed. 。
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 5 m
Ω 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. Safty Valve
Performance
(Over dis-
charging)
 to be charged with 1C
mA for 5
hours
 safety valve can work
normally, no breakage,
leakage, distortion and out
package breakage are allowed
20. Safty 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 4
hour。
