Specification Description: Minimum capacity: 3000mAh Typical capacity: 3050mAh Battery model: 103665 Nominal voltage: 3.7V Overcharge voltage: 4.2V Overdischarge voltage: 3.0v Maximum charge rate: 0.5C Maximum discharge rate: 0.5C Maximum charge current: 1.5A Charging temperature: 0-45°C Discharge temperature: -10-60°℃ Battery interface: Micro JST 1.25 Charging line interface: JST 1.25, USB Charging cable specifications: 3.7V-300mA Charging time: 10 hours Battery life: depends on the power consumption of the device. If the 3000mAh battery is continuously discharged at a current of 300mA, it can theoretically be used for 10 hours. If it is used for some small electronic devices with low power consumption, such as smart watches, the battery life may reach several days or even weeks; If it is used for devices with high power consumption, such as some high-brightness flashlights or tablets running large programs, the battery life may only be a few hours. Note: Charge: 1.Charging current: Charging current should be less than the maximum value. 2.Charging Voltage： Charging shall be done by voltage less than 4.4V/cell.Charging beyond 4.45V，which is the absolute maximum voltage，must be strictly prohibited. 3.Charging temperature： The cell shall be charged within the specified temperature range. 4.Prohibition of Reverse Charge： Reverse charge is prohibited.Cells shall be connected correctly.The polarity has to be confimed before wiring.In case of the cell is connected improperly，the cell cannot be charged.Simultaneously，the reverse charging may cause damage to the cell. Discharge: 1.Discharge Current： The cell shall be discharged at less than the maximum discharge current. 2. Discharge temperature The battery should be discharged within the specified temperature range. 3. Over-discharge The battery should be charged periodically to avoid over-discharge and keep the voltage between 3.7V and 3.9V. Over-discharge will lead to a decrease in the performance, characteristics or functions of the battery.
