All batteries have a higher voltage when fully charged, and a lower voltage when discharged. The range may be narrow or wide, depending on the chemistry of the battery. No battery works at "just" the voltage listed. Most lithium-ion batteries have a working range of about 25%. Each cell is about 3v at lowest charge, 4v or so fully charged.

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.
This point is commonly referred to as the “charging cut-off current.” II. Key Parameters in Lithium-ion Battery Charging Several crucial parameters are involved in lithium-ion battery charging: Charging Voltage: This is the voltage applied to the battery during the charging process.
Several crucial parameters are involved in lithium-ion battery charging: Charging Voltage: This is the voltage applied to the battery during the charging process. For lithium-ion batteries, the charging voltage typically peaks at around 4.2V.
Steady Voltage and Declining Current: As the battery charges, it reaches a point where its voltage levels off at approximately 4.2V (for many lithium-ion batteries). At this stage, the battery voltage remains relatively constant, while the charging current continues to decrease.
When charging, lithium-ion batteries typically use a current rate of 0.5C to 1C, where “C” represents the capacity in amp-hours. Thus, for a 100Ah battery, this translates to a charging current of 50 to 100 amps. However, most manufacturers recommend a lower charging current to prolong battery life, often around 0.2C for optimal performance.
The Charging Characteristics of Lithium-ion Batteries Charging a lithium-ion battery involves precise control of both the charging voltage and charging current. Lithium-ion batteries have unique charging characteristics, unlike other types of batteries, such as cadmium nickel and nickel-metal hydride.
