UN Test Data (Model:3UR18650-2-T0638) 1.Test Item:Impact (T6) P.8/10 2.Test Purpose: This test simulates an impact. 3.Test Procedure: The test sample cell or component cell is to be placed on a flat surface. A 15.8mm diameter bar is to be placed across the center of the sample. A 9.1kg mass is to be dropped from a height of 61±2.5cm onto the sample. A cylindrical or prismatic cell is to be impacted with its longitudinal axis parallel to the flat surface and perpendicular to the longitudinal axis of the 15.8mm diameter curved surface lying across the centre of the test sample. A prismatic cell is also to be rotated 90 degrees around its longitudinal axis so that both the wide and narrow sides will be subjected to the impact. Each sample is to be subjected to only a single impact. Separate samples are to be used for each impact. A coin or button cell is to be impacted with the flat surface of the sample parallel to the flat surface and the 15.8mm diameter curved surface lying across its center. SANYO Internal Procedure: As above. 4.Test Requirements: External temperature of test batteries does not exceed 170°C and there is no disassembly and no fire within six hours of this test. 5.Test Date:2009/10/21 6.Test Data: Cell No. Maximum Temperature(°C) Other event 1 120 0 Result PASS Judgement 2 126 0 PASS 3 122 0 PASS At first 4 135 cycle, 50% 5 139 charged 6 states 7 0 PASS 0 PASS 0 0 8 0 PASS 9 0 10 0 11 43 0 PASS 12 40 0 PASS 13 45 After 50 cycles 14 42 ending, in 15 41 fully 16 discharged 17 states 18 0 PASS 0 PASS 0 PASS 19 20 Notes: D-Disassembly, F-Fire, 0-No disassembly & no fire

1.Test Item:
Impact (T6)
P.8/10
2.Test Purpose:
This test simulates an impact.
3.Test Procedure:
The test sample cell or component cell is to be placed on a flat surface. A 15.8mm diameter bar is to be placed across
the center of the sample. A 9.1kg mass is to be dropped from a height of 61±2.5cm onto the sample.
A cylindrical or prismatic cell is to be impacted with its longitudinal axis parallel to the flat surface and perpendicular to
the longitudinal axis of the 15.8mm diameter curved surface lying across the centre of the test sample. A prismatic
cell is also to be rotated 90 degrees around its longitudinal axis so that both the wide and narrow sides will be subjected
to the impact. Each sample is to be subjected to only a single impact. Separate samples are to be used for each impact.
A coin or button cell is to be impacted with the flat surface of the sample parallel to the flat surface and the 15.8mm
diameter curved surface lying across its center.
SANYO Internal Procedure:
As above.
4.Test Requirements:
External temperature of test batteries does
not exceed 170°C and there is no disassembly and no fire within six hours
of this test.
