Remark

1

Charge Voltage

4.20±0.02V


2

Nominal Voltage

3.7V

Cell voltage between3.75V ~3.95V before shipping

3

Nominal Capacity

380mAh@ 0.2C Discharge

Nominal capacity refers to the capacity of 0.2C discharge with 3.0V cut-off voltage.

4

Cycle Life

≥500 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 3.0V

The cycle life is the cycle times when the discharge capacity is about 60% of the rated capacity.

5

Self-discharge

Residual Capacity>90%

After standard charging, storied at 25°C±0.5°C for 30 days, then measure the capacity as item 4.

6

Impedance

Max:200

After standard charging, measure the internal resistance with AC1KHz

3.0V


14

Operating Temperature

Charge: 0 ℃~ +45℃

Discharge: -20~ +60


15

Storage Temperature

Less than 1 year: -5~25℃

Cells must be storied at 3.75V~3.95V. During long period storage, cells should be maintained every 90 days. The method is to do a charge-discharge cycle with standard method, then charge to 3.75~3.95V.

Less than 3 months: -10~40℃
