The charging voltage of lithium batteries is usually 4.2V and 4.35V, and the voltage value will be different if the cathode and anode materials are different. The battery voltage is one of the important indicators to measure the discharge performance.
Source : Hunan Huaxing New Energy Technology Co. Lithium-ion cells can charge between 0°C and 60°C and can discharge between -20°C and 60°C. A standard operating temperature of 25±2°C during charge and discharge allows for the performance of the cell as per its datasheet.
When the cells are assembled as a battery pack for an application, they must be charged using a constant current and constant voltage (CC-CV) method. Hence, a CC-CV charger is highly recommended for Lithium-ion batteries. The CC-CV method starts with constant charging while the battery pack’s voltage rises.
The battery voltage is one of the important indicators to measure the discharge performance. Take the car battery voltage as example, on the circumstance of no-load, the normal voltage of the car battery is about 13V while the load voltage often exceeds 11V. It will be difficult to start when the voltage is lower.
