Test procedure

Requirements

8.1.1 Nominal Voltage

The average value of the working voltage during the whole discharge process.

3.6V

8.1.2 Discharge Performance

The discharge capacity of the cell, measured with 1.1 A down to 3.0V within 1 hour after a completed charge.

≥114min

8.1.3 Capacity Retention

After 28 days storage at 25±5℃, after having been completely charged and discharged at 0.52A, discharge to 3.0V, the residual capacity is above 90%

Capacity≥2150mAh

8.1.4 Cycle Life

After 300 cycles at 100% DOD. Charge and discharge at 1.1A, the residual discharge capacity is above 80% of nominal capacity.

≥300 cycles

8.1.5 Storage

(Within 3 months after manufactured) The cells is charged with 1.1A to 40-50% capacity and stored at ambient temperature 25±5℃, 65±20%RH for 12 months. After the 12 months storage period the cell is fully charged and discharged to 3.0V with 0.48A

Discharge time≥4h
