Cell Origin | purchased on free market |
Cell Format | 21700 |
Dimensions | 21.61 x 70.75 mm |
Weight | 68.9 g |
Capacity [definition][close]
The nominal capacity originates from the manufacturer’s data sheet, if available. When the data sheet is unavailable, the nominal capacity is estimated. Batemo measured the C/10 capacity by discharging the cell at an ambient temperature of 25°C from 100% with a constant current of 0.50A (0.1C) until reaching the voltage of 2.5V. The thermal boundary condition is free convection. |
nominal 5.00 Ah C/10 4.91 Ah |
Current [definition][close]
All quantities are measurement results of the Batemo battery laboratory. The continuous current is the highest current that completely discharges the cell without over-heating it. Therefor, the cell is discharged from 100% state of charge at an ambient temperature of 25°C with a constant current until reaching a residual state of charge of 10% and either the voltage of 2.5V or 90% of the maximum surface temperature of 63°C. The peak current is the current the cell can deliver for 5 minutes. Consequently, the cell is discharged from 100% SOC at an ambient temperature of 25°C with a constant current until reaching either the voltage of 2.5V or the surface temperature of 70°C after 5 minutes. The thermal boundary condition is free convection. These operational conditions might be outside the specification of the cell manufacturer. |

Energy [definition][close]
Batemo measured the C/10 energy by discharging the cell at an ambient temperature of 25°C from 100% with a constant current of 0.50A (0.1C) until reaching the voltage of 2.5V. The thermal boundary condition is free convection. |
C/10 18.0 Wh |
Power [definition][close]
All quantities are measurement results of the Batemo battery laboratory. The mean continuous power is the highest power that completely discharges the cell without over-heating it. Therefore, the cell is discharged from 100% state of charge at an ambient temperature of 25°C with a constant current until reaching a residual state of charge of 10% and either the voltage of 2.5V or 90% of the maximum surface temperature of 63°C. The peak power is the power the cell can deliver for 5 minutes. Consequently, the cell is discharged from 100% SOC at an ambient temperature of 25°C with a constant current until reaching either the voltage of 2.5V or the surface temperature of 70°C after 5 minutes. The thermal boundary condition is free convection. These operational conditions might be outside the specification of the cell manufacturer. |
