Capacity
[defin­i­tion]
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 5.30A (0.1C) until reaching the voltage of 2.5V. The thermal boundary condi­tion is free convection.

Current
[defin­i­tion]
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 54°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 60°C after 5 minutes. The thermal boundary condi­tion is free convec­tion. These opera­tional condi­tions might be outside the speci­fi­ca­tion of the cell manufacturer.
