3 Vibration
The battery will be vibrated 10 times in three mutually
perpendicular directions with amplitude of 0.35mm and
changing frequency between 10 and 55Hz. The rate of
scanning frequency is from 10Hz to 55Hz with the rate of
1Hz per min.

and pulse lasting time 16ms.
5 Free
fall
The battery will be dropped free five times in three mutually
perpendicular directions from the height of 1.0m onto a
hard board with the thickness of 20mm
The battery shall not
rupture, smoke, catch fire,
vent or leak.

INSTRUCTION
REQUIREMENTS
1 Short
Circuit
The battery is to be short-circuited by connecting the
positive and negative terminals of the battery with and
external load of less than 50
mΩ
2
Over charge
testing
According to the method of UL
3
Over
discharge
testing
After complete charge, the battery will be discharged to end
voltage. Then Connect with external load of 30
Ω
for 24hrs.
The battery shall not
rupture, smoke, catch fire,
vent or leak.
C.4.3 Cautions
1) The best operating performance is between -20 ~ +60 °C. Higher or lower temperature could cause
damage to the battery.
2) Operated with external power supply will not hurt battery life since battery does not discharge. Therefore, it
operating temperature range is -40 ~ +85°C.
3) Recharge the battery for 10 hours before use.
