Capacity:
The capacity is measured by discharging the cell at an ambient temperature of 25°C from 100% with a constant current C/10 until the lower voltage limit is reached.

Energy:
The energy is measured by discharging the cell at an ambient temperature of 25°C from 100% with a constant current of C/10 until the lower voltage limit is reached.

Power:
The peak power is the power the cell can supply for 5 minutes. The cell is therefore discharged from 100% SOC at an ambient temperature of 25°C with a constant current until it reaches either the lower voltage limit or the maximum surface temperature after 5 minutes. For cells that reach the maximum temperature limit, the measured power is directly taken as peak power. For cells that do not reach the maximum surface temperature after 5 minutes because they reach the lower voltage limit first, the measured power is multiplied by a correction factor that estimates the power that would have heated the cell to the maximum surface temperature within 5 minutes. The thermal boundary condition is free convection. These operating conditions may be outside the cell manufacturer’s specification.

Current:

The cell is therefore discharged from 100% SOC at an ambient temperature of 25°C with a constant current until it reaches either the lower voltage limit or the maximum surface temperature after 5 minutes.
