Specification
4.4.1
Drop Test
Cells charged per 4.1.1 are dropped onto an wooden
floor from 4 feet height for 3 cycles, 2 drops from each
cell terminal and 1drop from the side of cell can (Total
number of drops = 9).
No leakage
No temperature rising
4.4.2
Vibration Test
Cells charged per 4.1.1 are vibrated for 90 minutes per
each of the three mutually perpendicular axis (x, y, z)
with total excursion of 0.8mm, frequency of 10Hz to
55Hz and sweep of 1Hz change per minute
No leakage

Specification
4.5.1
Overcharge Test
Cells are discharged per 4.1.2, then charged at constant
current of 3 times the max. charge condition and
constant voltage of 4.2V while tapering the charge
current. Charging is continued for 7 hours (Per UL1642).
: No explode, No fire
4.5.2
External Short -
Circuiting Test
Cells are charged per 4.1.1, and the positive and
negative terminal is connected by a 100m
Ω
-wire for 1
hour (Per UL1642).
: No explode, No fire
4,5.3
Overdischarge
Test
Cells are discharged at constant current of 0.2C to
250% of the minimum capacity.
: No explode, No fire
4.5.4
Heating Test
Cells are charged per 4.1.1 and heated in a circulating
air oven at a rate of 5ºC per minute to 130ºC. At 130ºC,
oven is to remain for 10 minutes before test is
discontinued (Per UL1642).
: No explode, No fire
4.5.5
Impact Test
Cells charged per 4.1.1 are impacted with their
longitudinal axis parallel to the flat surface and
perpendicular to the longitudinal axis of the 15.8mm
diameter bar (Per UL1642).
: No explode, No fire
4.5.6
Crush Test
Cells charged per 4.1.1 are crushed with their
longitudinal axis parallel to the flat surface of the
crushing apparatus (Per UL1642).
: No explode, No fire
