UN Test Data (Model:3LUNA-1-T0636)
1.Test Item:
Thermal Test (T2)
P.4/10
2.Test Purpose:
This test assesses cell and battery seal integrity and internal electrical connections. The test
is conducted using rapid and extreme temperature changes.
3.Test Procedure:
Test cells and batteries are to be stored for at least six hours at a test temperature equal to 75±2
℃
, followed
by storage for at least six hours at
a test temperature equal to -40±2
℃
.The maximum time internal between
test temperature extremes is 30 minutes.This procedure is to be repeated 10 times, after which all test cells
and batteries are to be stored for 24 hours at ambient temperature (20 ±5
℃
). For large cells and batteries the
duration of exposure to the test temperature extremes should be at least 12 hours.
SANYO Internal Procedure:
As above.
4.Test Requirements:
No mass loss(less than 0.1%),no leakage,no venting,no disassembly,no rupture and no fire,and the voltage
retention is not less than 90%.
The requirement relating to voltage is not applicable to test batteries at fully discharged states.
