A lead acid battery voltage chart is crucial for monitoring the state of charge (SOC) and overall health of the battery. The chart displays the relationship between the battery’s voltage and its SOC, allowing users to determine the remaining capacity and when to recharge.
The charging voltage should be increased when the temperature of the battery is low and decreased when the temperature of the battery is high. The voltage of a lead-acid battery also varies with temperature. At room temperature, the voltage of a fully charged lead-acid battery is around 12.6 volts.
When the lead acid battery is discharging, the active materials of both the positive and negative plates are reacted with sulfuric acid to form lead sulfate. After discharge, the concentration of sulfuric acid in the electrolyte is decreased, and results in the increase of the internal resistance of the battery.
The minimum open circuit voltage of a 12V sealed lead acid battery is around 12.2 volts, assuming 50% max depth of discharge. The minimum open circuit voltage of a 12V flooded lead acid battery is around 12.1 volts, assuming 50% max depth of discharge. How much can you discharge a lead acid battery?
At 0% charge, a 12V lead acid battery will have an 11.36V voltage. This is a full 1.37V difference between 100% and 0% charge. Onward to 24 lead acid battery chart: We see the same lead-acid discharge curve for 24V lead-acid batteries as well; it has an actual voltage of 24V at 43% capacity.
The charging voltage of a lead-acid battery should be adjusted according to the temperature of the battery. The charging voltage should be increased when the temperature of the battery is low and decreased when the temperature of the battery is high. The voltage of a lead-acid battery also varies with temperature.
Lead–acid battery
Overcharging with high charging voltages generates oxygen and hydrogen gas by electrolysis of water, which bubbles out and is lost. The design of some types of lead–acid battery (eg "flooded", but not VRLA (AGM or gel)) allows the electrolyte level to be inspected and topped up with pure water to replace any that has been lost this way.
