Characteristics of INR18650 20Q

1 Standard charge

This “Standard charge” means charging the cell CCCV with charge current 0.5CmA (1,000mA), constant voltage 4.2V and 20mA cut-off in CV mode at 25℃ for capacity. .

2 Rapid charge

Rapid charge means charging the cell CCCV with charge current 4A and 100mA cut-off at 25℃

 3 Nominal discharge capacity

The standard discharge capacity is the initial discharge capacity of the cell, which is measured with discharge current of 400mA with 2.0V cut-off at 25℃ within 1hour after the standard charge.

Nominal discharge capacity ≥ 2,000mAh

4 Standard rated discharge capacity

The standard rated discharge is the discharge capacity of the cell, which is measured with discharge current of 10A with 2.0V cut-off at 25℃ within 1hour after the standard charge.

Standard rated discharge capacity ≥ 1,950mAh

5 Initial internal impedance

Initial internal impedance measured at AC 1kHz after standard charge

Initial internal impedance ≤ 18mΩ

6 Temperature dependence of discharge capacity

Capacity comparison at each temperature, measured with discharge constant current 10A and 2.0V cut-off after the standard charge is as follows.

Discharge temperature
-20℃ -10℃ 0℃ 25℃ 60℃
60% 75% 80% 100% 100%

Note: If charge temperature and discharge temperature is not the same, the interval for temperature change is 3 hours.

Percentage index of the discharge at 25℃ at 10A (=1,950mAh) is 100%.

7 Temperature dependence of charge capacity

Capacity comparison at each temperature, measured with discharge constant current 10A and 2.0V cut-off after the standard charge is as follows.

Discharge temperature Discharge temperature
-20℃ -10℃ 0℃ 25℃ 60℃ 25℃
Relative capacity 60% 75% 80% 100% 100%

Note: If charge temperature and discharge temperature is not the same, the interval for temperature change is 3 hours.

Percentage index of the discharge at 25℃ at 10A (=1,950mAh) is 100%.

8 Charge rate capabilities

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

Charge condition
Current Standard 1A Maximum rapid charge 4A
Cut-off 100mA 100mA
Relative Capacity 100% 98%
