A 12V sealed lead acid battery will have an open circuit voltage of around 12.9 volts when fully charged. A 12V flooded lead acid battery will have an open circuit voltage of around 12.6 volts when fully charged.
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.
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. As always, defer to the recommended float voltage listed in your battery’s manual. Some brands refer to float as “standby.”
The 12 Volt Battery Voltage Chart is a useful tool for determining the state of charge (SOC) of your battery. The chart lists the voltage range for different levels of charge, from fully charged to fully discharged.

How to test a lead-acid battery
Well what you need to learn first is the voltage range in which a lead-acid battery should be operating. A healthy, fully charged battery should be sitting at 12.7 – 12.8 volts. And at the other end of the scale, a lead-acid battery is considered fully discharged when it reaches 12.0 volts. Finally, to remain healthy, a lead-acid battery should be at least above 12.5volts at all times.
