After fully charge, place the battery in the
environment of 40±2℃ and 90% - 95%
Relative humidity for 48 hours, then place
it in 20±5℃ for 2 hours, later, discharge
with 1C5A to cut-off voltage.
Batteries are vibrated 30 minutes in three
mutually perpendicular directions of X, Y,
Z with amplitude of 0.38mm (10~55Hz)
and the scanning rage of 1oct per minute.
Vibration test ended, place the battery in
the directions of X.Y.Z three mutually
perpendicular axis, and set pulse peak
acceleration as 100m//s2. Then shock the
battery with frequency of 40 ~ 80 per
minute. The duration of pulse is 16ms,
Shock times: 2000 ± 10.
After shock test, the batteries are
dropped on the 18-20mm hardwood on
the concrete floor from 2000mm height
as per positive and negative 6 direction
of X, Y, Z. Each direction should drop
one time. After test, batteries can be
charged and discharged for at least
three cycles.
After fully charged, continue to charge the
battery for 8 hours with C.C/C.V source.
The constant voltage source sets to 2
times nominal voltage and constant
current sets 2 C5A.
At 20±5℃, discharge the battery
discharge with 0.2C5A to cut-off voltage.
Then, continuously discharge the battery
with a 30Ω load resistance for 24 hours.
After fully charge, short-circuit positive
and negative electrode with 0.1Ω for 1
hour. Cut-off positive and negative
electrode, then charge the battery at
0.5C5A instantaneously for 5S.

drops to about 10℃ lower than the max
temperature, test is finished.
Place battery connected thermocouple
in a ventilated cabinet, short-circuit the
positive and negative, then monitor the
changes
of
temperature.
If
the
temperature of battery drops to about
10℃ lower than the max temperature,
test is finished.
Put battery in the nail test platform.
then, use a diameter 8 mm steel tip to
poke through into hole.
Finally, use a heavy hammer to blow the
battery
At 20±5℃,charge battery with 0.5 C5A to
4.2V and then charge it with constant
voltage to the current less than 20mA.
Stop charge and display for 0.5~1 hour.
Then discharge it with 1 C5A to cut-off
voltage. Display for 0.5 ~1 hour, do next
charge and discharge cycle. Repeat
these steps. Stop it until the continuous
two cycle discharge time is less than 48
minutes.
