Charge Voltage

                4.2V

Nominal Voltage

                3.7V

The average value of voltage during the discharge period (with standard charge and discharge). When shipping, the voltage without load is between 3.6V and 3.85V.

Nominal Capacity

Typ:10mAh@0.2C

Discharge

Min：10mAh

Nominal Capacity refer to the capacity of0.2Cdischarge to 2.8V cut-off voltage, after charging with standard method.

Standard Charging method

              CC/CV

0.2CCC(constant current) charge to 4.2V, thenCV(constant voltage 4.2V) charge till charge current decline to ≤ 0.05C

Cycle Life

     ³ 300 Times

One cycle refer to one charge period and then one discharge period.

Test condition:

Charge:0.2Cto 4.2V

Discharge:0.2Cto 2.8V

The cycle life is the cycle times when the discharge capacity is about 75% of the rated capacity.

Voltage:3.8±0.1V

Cells must be stored at 3.6V ~ 3.85V. Over long storage periods cells should be cycled every 90 days. The method is to do a charge-discharge cycle with standard method, then charge to 3.6V ~ 3.85V.
