Lead acid battery voltage curves vary greatly based on variables like temperature, discharge rate and battery type (e.g. sealed, flooded). The voltage to battery capacity chart in your battery manual should always take precedence over the generic, averaged ones listed below.
A lower voltage reading on the Lead Acid Battery Voltage Chart generally suggests a lower state of charge in the battery. It indicates that the battery has less available energy and may require charging to maintain its optimal performance. Can the Lead Acid Battery Voltage Chart be used for all lead acid batteries?
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?

No, the Lead Acid Battery Voltage Chart is specifically designed for lead acid batteries. Other battery chemistries, such as lithium-ion or nickel-cadmium, have different voltage characteristics and require separate voltage charts or documentation for accurate analysis of their state of charge.
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?
