Charge Current 2600mA(ambient temperature 25℃) 3.9 Max. Discharge Current 5200mA(ambient temperature 25℃) 3.10 Discharge Cut-off Voltage 2.75V 3.11 Cell Weight 47.0g max 3.12 Cell Dimension Height : 65.00mm max Diameter : 18.40mm max 3.13 Operating Temperature 3.14 Storage Temperature Charge : 0 to 45℃ Discharge: -20 to 60℃ 1 year : -20~25℃(1*) 3 months : -20~45℃(1*) 1 month : -20~60℃(1*) Note (1): If the cell is kept as ex-factory status (50% of charge), the capacity recovery rate is more than 80%. 2 -SAMSUNG SDI Confidential Proprietary – Spec. 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 Init […]
