401030 / 90mAh
Charge Limited Voltage
Cell shipping Voltage between 3.6V ~3.9V before
90mAh@ 0.2C Discharge
Nominal Capacity refer to the capacity of 0.2C discharge with 2.75V cut-off voltage, after charging with standard method.
One cycle refer to one charge period and then one discharge period. Test condition: Charge: 0.2C to 4.2V Discharge: 0.2C to 2.75V The cycle life is the cycle times when the discharge capacity is about 80% of the rated capacity.
After standard charging, storied at 25°C±0.5°C for 30 days, then measure the capacity as item 4.
After standard charging, measure the internal resistance with AC1KHz
