When charging a lithium-ion battery, the charger uses a specific charging algorithm for lithium-ion batteries to maximise their performance. Select LI-ION using the MODE button.
As for the specification of the cell, the charging current range is from 1A to 4A (0.67C to 2.67C), the discharge current range is between 7.5A and 15A (5C–10C), while the voltage range is 4.2∼2.5 V. The recommended current for a fast charge is 4A from the battery manufacturer.
Lithium-ion batteries accept a maximum charge current of 1C or less, where 1C refers to the capacity of 1 times the current to the charge over 1 hour. However, some devices, like laptops, often have a maximum of 0.9C, and to extend lithium-ion battery lifespan, using 0.5C or less is recommended.

Going below this voltage can damage the battery. Charging Stages: Lithium-ion battery charging involves four stages: trickle charging (low-voltage pre-charging), constant current charging, constant voltage charging, and charging termination. Charging Current: This parameter represents the current delivered to the battery during charging.
Here is a general overview of how the voltage and current change during the charging process of lithium-ion batteries: Voltage Rise and Current Decrease: When you start charging a lithium-ion battery, the voltage initially rises slowly, and the charging current gradually decreases. This initial phase is characterized by a gentle voltage increase.
Charging Termination: The charging process is considered complete when the charging current drops to a specific predetermined value, often around 5% of the initial charging current. This point is commonly referred to as the “charging cut-off current.” II. Key Parameters in Lithium-ion Battery Charging
The lithium battery charging algorithm consists of constant current and constant voltage stages. After the constant voltage stage, the battery should be disconnected to prevent overcharging. Periodically, the battery can receive small charges to keep it full. Figure 1 provides a visual overview of how a lithium battery is charged.
