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.
The voltage of a lead acid battery decreases under load, which means that the voltage will be lower when the battery is powering a device than when it is not. The amount of voltage drop depends on the load and the capacity of the battery. What is the critical low voltage threshold for a lead acid battery?
