4. Performance
Unless otherwise stated, tests should be conducted under the following conditions:
Time frame Within one month of delivery
Ambient temperature 20 ± 5ºC
Relative Humidity 65 ± 20%
4.1 Standard Capacity
The initial capacity is the discharge capacity of the cell measured with a discharge current of 0.2C to a discharge end-off voltage of 2.75V within 30 minutes after the standard charge.
Up to three cycles are permitted for this test.
Discharge capacity = 1400mAh
4.2 Open Circuit Voltage
The open circuit voltage is above 3.75V within one hour after standard charge
4.3 Initial Impedance (for reference only)
The initial internal resistance is measured at 1KHz within 30 minutes after standard charge.
Initial Impedance = 150mOhm
4.4 Fast Discharge Capacity
Fast discharge capacity is measured with a discharge current of 1C to a discharge end-off voltage of 2.75V after standard charge.
Fast discharge capacity = 1260mAh
4.5 Charge Retention
After standard charge and storage time of 28 days at ambient temperature, the capacity is measured with a discharge current of 0.2C to a discharge end-off voltage of 2.75V.
Capacity = 1190mAh
4.6 Discharge capacity at -10?
After the standard charge, the battery is stored in an ambient temperature of -10?±2? for not less than 16h and not more than 24h. The capacity is measured with a discharge current of 0.2C to a discharge end-off voltage of 2.75V.
Discharge capacity = 980mAh.
4.7 Discharge capacity at 55?
After the standard charge, the battery is stored in an ambient temperature of 55?±2? for not less than 16h and not more than 24h. The capacity is measured with a discharge current of 0.2C to a discharge end-off voltage of 2.75V.
Discharge capacity = 1260mAh.
