BAK B18650CC--2.2Ah performance report 2012-5 Summery of Safety test result: High-Low temperature discharge performance 5.4.4 Storage Performance -Test inspection: - After standard fully charge, according to standard charge method, the cell is discharged according to standard discharge method. - Perform 10 cycles to check capacity. Finishing fully charged. Record capacity of 10th cycle. The 10th cycle discharge capacity is called the original discharge capacity. Then the cell is fully charged according to standard charge method and stored at 25℃ for 1month. - After storage, the cell is discharged according to the requirement of standard discharge method. This discharge capacity is named by the Residual capacity. And than charge and discharge the cell by 0.5C. The discharge capacity is named by the Recovery capacity. - Pass Criteria: 5.6.3 Hot oven test （130℃） Test inspection: Place the battery in an oven and heat it up to 130℃ at a rate of 5℃/min. Then hold the battery at 105℃ for a duration of 1 hours Pass Criteria: When the temperature of the cell is 130℃. Cell must not fire or explode in 60 minutes NASDAQ: CBAK NASDAQ: CBAK Discharge capacity of 500th cycle/ Original capacity≥80%. Charge at 1C, discharge at:1C, 500 cycles. Room temp.
