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. On the other hand, when a battery discharges, the voltage drops as the gadget draws power from the battery.
However, this is only partially true. The lithium-ion battery’s voltage increases as it charges, but the relationship is not linear. It can vary based on several factors, including the battery’s age and temperature. For instance, a typical lithium-ion cell might show a voltage of 3.7V at 50% charge.
The chemistries of lead-acid and lithium-ion batteries differ, impacting their voltage properties, particularly full charge voltages. A single lead-acid battery has a nominal voltage of 2.0 volts. Lead-acid battery full charge voltage is 2.41 volts.
It’s a common belief that the voltage of a lithium-ion battery can accurately indicate its charge state. However, this is only partially true. The lithium-ion battery’s voltage increases as it charges, but the relationship is not linear. It can vary based on several factors, including the battery’s age and temperature.
The notion that lithium-ion batteries should constantly be fully recharged to 100% before use is another myth. Data shows that partial charges can be more beneficial. According to Battery University, lithium-ion batteries do not require a complete charge cycle, and partial discharges with frequent recharges are preferable.
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.
