UN Test Data (Model:3UR18650-2-T0590) 1.Test Item: Thermal Test (T2) 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. P.4/10 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. 5.Test Date: 2007/10/17 6.Test Data Battery No. Mass(g) Mass Voltage(V) Voltage loss (%) Retention( Before test After test (=90%) Other event Result Judgement At first 1 294.50 294.43 0.024 12.52 12.36 98.7 PASS cycle,in 2 293.71 293.65 0.020 12.52 12.36 98.7 fully charged 3 294.30 294.27 0.010 12.52 12.36 98.7 PASS PASS states 4 294.02 293.91 0.037 12.52 12.35 98.6 PASS At first 5 294.67 294.60 0.024 cycle,in 6 fully discharged 7 294.79 294.76 294.71 294.70 0.027 0.020 states 8 294.50 294.43 0.024 After 50 9 294.13 294.08 0.017 12.55 12.40 98.8 cycles ending in 10 294.68 294.65 0.010 12.55 12.40 98.8 fully 11 294.67 294.63 0.014 12.56 12.40 98.7 charged states 12 294.05 294.01 0.014 12.56 12.40 98.7 After 50 13 294.55 294.50 cycles 0.017 ending in 14 294.60 294.56 0.014 fully 15 294.12 discharged states 16 294.38 294.10 294.32 0.007 0.020 Notes: L-Leakage, V-Venting, D-Disassembly, R-Rupture, F-Fire, 0-No leakage, no venting, no disassembly, no rupture & no fire PASS PASS PASS PASS PASS PASS PASS PASS PASS PASS PASS PASS PASS
