Characteristics of ICR18650 26F

1 Standard Charge

This “Standard Charge” means charging the cell with charge current 1300mA and constant voltage 4.2V at 25℃ for 3hours.

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

3 Initial internal impedance

Initial internal impedance measured at AC 1kHz after rated charge.

Initial internal impedance ≤ 100mΩ

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 Discharge temperature
25°C -10°C 0°C 25°C 40°C
Relative Capacity 50% 80% 100% 80%

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%.

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.

Charge temperature Discharge temperature
0°C 25°C 45°C 25°C
Relative Capacity 80% 100% 100%

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.Discharge Rate Capabilities

Discharge capacity is measured with the various currents in under table and 2.75V cut-off after the standard charge.

Charge temperature
Current 0.2C(520mA) 0.5C(1300mA) 1.0C(2600mA) 2.0C(5200mA)
Relative Capacity 100% 95% 90% 80%
