For a typical 12 V battery v s varies from 12.7 V fully charged to 11.7 V when the battery is almost fully discharged. Internal resistance R S is also a function of the state of charge and temperature. When the battery provides current, there is a voltage drop across R S, and the terminal voltage v < v s. To charge the battery, a voltage v > v
For instance, a 12V sealed lead acid battery has a voltage of 12.89V at 100% charge, while 11.63V indicates it is at 0% charge. The good news is that you can refer to a lead acid battery voltage chart to find the

A lower voltage reading on the Lead Acid Battery Voltage Chart generally suggests a lower state of charge in the battery. It indicates that the battery has less available energy and may require charging to maintain its optimal performance. Can the Lead Acid Battery Voltage Chart be used for all lead acid batteries?
A lead acid battery is considered fully charged when its voltage level reaches 12.7V for a 12V battery. However, this voltage level may vary depending on the battery’s manufacturer, type, and temperature. What are the voltage indicators for different charge levels in a lead acid battery?
The nominal voltage of a lead acid battery is the voltage level that the battery is designed to operate at. For example, a 12-volt lead acid battery has a nominal voltage of 12 volts. However, the actual voltage of a lead acid battery can vary depending on its state of charge, temperature, and other factors.
Temperature affects lead acid battery voltage levels. The voltage level of a lead acid battery increases as the temperature decreases and vice versa. Therefore, you need to consider the temperature when measuring the voltage level of a lead acid battery. At what voltage level is a lead acid battery considered fully charged?
The resting voltage of a 12V lead acid battery refers to the voltage measured when the battery is not under load (i.e., not connected to any circuits or devices). After a period of rest, a fully charged battery should have a resting voltage around 12.6 to 12.8 volts.
Meanwhile, the float voltage of a sealed 12V lead acid battery is usually 13.6 volts ± 0.2 volts. The float voltage of a flooded 12V lead acid battery is usually 13.5 volts.
