Test Sample Specifications Nominal Capacity = 3400 mAh Graphite / NCA 18650 Cell Cycling Protocol - Normal (N) Voltage Window Charge: CCCV at C/2 up to 4.2 V and a 50 mA cutoff current Discharge: CC at C/2 down to 2.7 V Cycling Protocol - Reduced (R) Voltage Window Charge: CCCV at C/2 up to 4.0 V and a 50 mA cutoff current Discharge: CC at C/2 down to 2.9 V Cycling Life Capacity fade and number of cycles are included in the filename. Example: File = 'Ba01_N20_OV1_300.xls' N20 = 20% Capacity fade under the normal voltage window Number of Cycles = 300

N stands for normal voltage window R stands for reduced voltage window OV indicates the cell was overcharged at the end of the aging test EX indicates the cell was externally shorted at the end of the aging test
