Spec | Note |
| Charge Voltage | 4.2V | |
| Overcharge protection voltage | 4.28±0.08V | |
| 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:105mAh@ 0.2C Discharge Min:105mAh |
Nominal Capacity refer to the capacity of 0.2C discharge to2.8V cut-off voltage, after charging with standard method. |
