No. ICR18650-26H Version No. 1.0 4. Outline Dimensions See the attachment (Fig. 1) 5. Appearance There shall be no such defects as scratch, rust, discoloration, leakage which may adversely affect commercial value of the cell. 6. Standard Test Conditions 6.1 Environmental Conditions Unless otherwise specified, all tests stated in this specification are conducted at temperature 25±5℃ and humidity 65±20%. 6.2 Measuring Equipment (1) Ammeter and Voltmeter The ammeter and voltmeter should have an accuracy of the grade 0.5 or higher. (2) Slide caliper The slide caliper should have 0.01 mm scale. (3) Impedance meter The impedance meter with AC 1kHz should be used. 7. Characteristics 7.1 Standard Charge This "Standard Charge" means charging the cell with charge current 1300mA and constant voltage 4.2V at 25℃ for 3hours. 7.2 Standard Discharge Capacity The standard discharge capacity is the initial discharge capacity of the cell, which is measured with discharge current of 520mA with 2.75V cut-off at 25℃ within 1hour after the standard charge. Standard Discharge Capacity ≥ 2550mAh 7.3 Initial internal impedance Initial internal impedance measured at AC 1kHz after rated charge. Initial internal impedance ≤ 100mΩ 7.4 Temperature Dependence of Discharge Capacity Capacity comparison at each temperature, measured with discharge constant current 520mA and 2.75V cut-off after the standard charge is as follows. Charge Temperature 25℃ Relative Capacity -10℃ 50% Discharge temperature 0℃ 25℃ 80% 100% 40℃ 80% Note: If charge temperature and discharge temperature is not the same, 3 -SAMSUNG SDI Confidential Proprietary – Spec. No. ICR18650-26H Version No. 1.0 the interval for temperature change is 3 hours. Percentage as an index of the capacity at 25℃(=2550mAh) is 100%. 7.5 Temperature Dependence of Charge Capacity Capacity comparison at each temperature, measured with discharge constant current 520mA and 2.75V cut-off after the standard charge is as follows. Relative Capacity Charge temperature 0℃ 25℃ 45℃ 80% 100% 80% Discharge temperature 25℃ Note: If charge temperature and discharge temperature is not the same, the interval for temperature change is 3 hours. Percentage as an index of the capacity at 25℃(=2550mAh) is 100%. 7.6 Charge Rate Capabilities Discharge capacity is measured with constant current 520mA and 2.75V cut-off after the cell is charged with 4.2V as follows. Current Cut-off Relative Capacity 0.2C (520mA) 7h or 0.05C 100% Charge Condition 0.5C (1300mA) 1.0C (2600mA) 2.5h or 0.05C 2.5h or 0.05C 2.0C (5200mA) 2.5h or 0.05C 95% 90% 80% Note: Percentage as an index of the capacity at 25℃(=2550mAh) is 100%. 7.7 Discharge Rate Capabilities Discharge capacity is measured with the various currents in under table and 2.75V cut-off after the standard charge. Current Relative Capacity 0.2C (520mA) 100% Discharge Condition 0.5C (1300mA) 1.0C (2600mA) 95% 90% 2.0C (5200mA) 80% Note: Percentage as an index of the capacity at 25℃(=2550mAh) is 100%. 7.8 Cycle Life Each cycle is an interval between the charge (charge current 1300mA) with 2.5h or 4 -SAMSUNG SDI Confidential Prop.
