2. Description
2.1 Model: 0762100
3. Specification
3.1 The fundamental parameters of the cell
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:300mAh@ 0.2C Discharge
Min:250mAh
Nominal Capacity refer to the capacity of 0.2C discharge to 2.8V cut-off voltage, after charging with
standard method.
4 Charge Current Cell surface Temperature Charge Current
<0ºC Charge shall be prohibited
0ºC~300ºC 0.1C Max(CV:4.1V Max)
300ºC~15ºC 0.2C Max
15ºC~25ºC 0.5C Max
25ºC~45ºC 1.0C Max
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 not less than 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.
7 ,Initial
