The lithium battery full charge voltage range is such that they are deemed wholly charged when the voltage hits about 4.2 V. Some batteries can reach 4.35V at full charge. It’s crucial to remember that going beyond this voltage might result in overcharging, which can be dangerous and shorten the battery’s life.
The voltage between a battery’s terminals fluctuates when charged or drained. A lithium battery’s full charge voltage rises as it is charged. For instance, when a lithium-ion battery is ultimately charged, the voltage may increase from its nominal value—roughly 3.7 volts for a single cell—to around 4.2 volts.
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.
Lithium-ion batteries operate differently. They charge under a constant current and switch to a continuous voltage later in the charging cycle. The charging process reduces the current as the battery reaches its full capacity to prevent overcharging.
The nominal voltage of a 3.7 V lithium-ion battery could be 3.7 V, 3.65 V or 3.6 V. Charge/discharge cutoff voltage: The voltage levels at which a battery ceases to be charged or discharged to protect it from harm are referred to as the charge/discharge cutoff voltage.
Charge/discharge cutoff voltage: The voltage levels at which a battery ceases to be charged or discharged to protect it from harm are referred to as the charge/discharge cutoff voltage. The cutoff voltage for a 3.7 V lithium-ion battery is usually 3.0 V (discharge) or 4.2-4.35 V (full charge).
