Thermal Cycling
Shock-IEC 60086-5
Repeat the following temperature cycle 10 times:

Heat to +70°C within 30 minutes, hold for 4 hours.

Cool to +20°C within 30 minutes, hold for 2 hours.

Cool to -20°C within 30 minutes, hold for 4 hours.


No fire, No
explosion
No fire, No
explosion
Over Discharge Test
Discharge one fresh battery under IEC 60086-2, with
highest MAD value until on-load voltage falls to (n x
0.6v)”n” is the number of cells. Then, connect 3 fresh
batteries of the same brand, type and origin in series.
Continue discharge until voltage falls to four times (n x
0.6v).
The value of the resistor shall be approximately four
times the lowest value from the resistive load
IEC60086-2.The final value of the resistor shall be the
nearest value to that prescribed in 6.4 of IEC 60086-1

Safety Vent Test
Put 4 fresh batteries in a series ring connection with
one battery with reversed polarity for 1 day. Remove
batteries from circuit and observe for 7 days. Safety
vent shall operate.
