What is the state of charge of a lead acid battery?

The state of charge (SOC) of a lead acid battery refers to the amount of charge remaining in the battery. The SOC of a lead acid battery can be determined by measuring its voltage using a multimeter or other device. As the battery discharges, its voltage level decreases. Conversely, as the battery is charged, its voltage level increases.

What is the float voltage of a 12V lead acid battery?
