A fully charged lead acid battery typically measures between 12.6 and 12.8 volts, while a 50% SOC corresponds to around 12.0 volts. The voltage continues to decrease as the battery discharges, with 11.8 volts indicating a 25% SOC and 11.6 volts representing a nearly depleted battery at 0% SOC.
Discharging a lead acid battery below its recommended voltage can cause permanent damage to the battery. It can also reduce the battery’s capacity and lifespan. Therefore, it is essential to avoid discharging the battery below its recommended voltage level. This will ensure its long-term health and performance.
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 nominal voltage of lead acid is 2 volts per cell, however when measuring the open circuit voltage, the OCV of a charged and rested battery should be 2.1V/cell. Keeping lead acid much below 2.1V/cell will cause the buildup of sulfation. While on float charge, lead acid measures about 2.25V/cell, higher during normal charge.
A lead acid battery consists of electrodes of lead oxide and lead are immersed in a solution of weak sulfuric acid. Potential problems encountered in lead acid batteries include: Gassing: Evolution of hydrogen and oxygen gas. Gassing of the battery leads to safety problems and to water loss from the electrolyte.
A flooded lead-acid battery has a different voltage range than a sealed lead-acid battery or a gel battery. An AGM battery has a different voltage range than a 2V lead-acid cell. According to the provided search results, the voltage range for a flooded lead-acid battery should be between 11.95V and 12.7V.
