Capacity
definĀ­iĀ­tion
The nominal capacity origiĀ­nates from the manufacĀ­turĀ­erā€™s data sheet, if availĀ­able. When the data sheet is unavailĀ­able, the nominal capacity is estimated. Batemo measured the C/10 capacity by discharging the cell at an ambient temperĀ­aĀ­ture of 25Ā°C from 100% with a constant current of 2.30A (0.1C) until reaching the voltage of 1.5V. The thermal boundary condiĀ­tion is free convection.

Current
definĀ­iĀ­tion
All quantiĀ­ties are measureĀ­ment results from the Batemo battery laboraĀ­tory.
The continĀ­uous current is the highest current that completely discharges the cell without overheating it. ThereĀ­fore, the cell is discharged from 100% state of charge (SOC) at an ambient temperĀ­aĀ­ture of 25Ā°C with a constant current until a residual state of charge of 10% and either the lower voltage limit of 1.5V or 90% of the maximum surface temperĀ­aĀ­ture (50Ā°C) is reached.
The peak current is the current that the cell can supply for 5 minutes. The cell is thereĀ­fore discharged from 100% SOC at an ambient temperĀ­aĀ­ture of 25Ā°C with a constant current until it reaches either the lower voltage limit of 1.5V or the maximum surface temperĀ­aĀ­ture of 55Ā°C after 5 minutes. For cells that reach the maximum surface temperĀ­aĀ­ture, the measured current is taken directly as the peak current. For cells that do not reach the maximum surface temperĀ­aĀ­ture after 5 minutes because they reach the lower voltage limit first, the measured current is multiĀ­plied by a correcĀ­tion factor that estimates the current that would have heated the cell to the maximum surface temperĀ­aĀ­ture within 5 minutes.
The thermal boundary condiĀ­tion is free convecĀ­tion. These operating conditions may be outside the cell manufacturerā€™s specification.
