Nominal Specification of INR18650-13B

Note

1): If the cell is kept as ex-factory status (50% of charge), the capacity recovery rate is more than 90%.

Characteristics of INR18650 13B

1 Standard Charge

This “Standard Charge” means charging the cell with charge current 650mA and constant voltage 4.2V  100mA at 25℃ .

2 Standard Discharge Capacit

The standard discharge capacity is the initial discharge capacity of the cell, which is measured with discharge current of 1300mA with 2.5V cut-off at 25℃ within 1hour after the standard charge.

Standard Discharge Capacity ≥ 1250mAh

3 Standard rated discharge capacity
The standard discharge capacity is the initial discharge capacity of the cell, which is measured with discharge current of 10A with 2.5V cut-off at 25℃ within 1hour after the standard charge.

Standard rated discharge Capacity ≥1,250mAh

4 Initial internal impedance

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

Initial internal impedance ≤ 25mΩ

5 Temperature Dependence of Discharge Capacity

Capacity comparison at each temperature, measured with discharge constant current 10A and 2.5V cut-off after the standard charge is as follows.

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℃(=1250mAh) is 100%.

6. Temperature Dependence of Charge Capacity

Capacity comparison at each temperature, measured with discharge constant current 10A and 2.5V cut-off after the standard charge is as follows.

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℃(=1250mAh) is 100%.

7.Discharge Rate Capabilities

Discharge capacity is measured with the constanr current 10A and 2.5V cut off after the cell is charged with 4.2V as follows:
