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.
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 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.
Charge temperature | Discharge temperature | |||||
---|---|---|---|---|---|---|
0°C | 5°C | 25°C | 45°C | 50°C | 25°C | |
Relative Capacity | 80% | 90% | 100% | 95% | 95% |
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:
Charge Condition | ||
---|---|---|
Current | 0.65A | Rapid 4A |
