1

Charge Voltage

4.2V

2

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.

3

Nominal Capacity

Typ:10mAh@ 0.2C

Discharge

Min：10mAh

Nominal Capacity refer to the capacity of 0.2C discharge to 2.8V cut-off voltage, after charging with standard method.

5

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

6

Cycle Life

³ 300 Times

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

Test condition:

Charge:0.2C to 4.2V

Discharge: 0.2C to 2.8V

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

Operating Temperature

Discharge: -10℃~ +60℃

Charge: 0℃~ +45℃

11

long term storage temperature

-5 ℃~+35℃

Relative humidity: 45~75%RH

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.
