Although a lead acid battery may have a stated capacity of 100Ah, it''s practical usable capacity is only 50Ah or even just 30Ah. If you buy a lead acid battery for a particular application, you probably expect a certain lifetime from it, probably in years. If the battery won''t last this long, it may not be an economically viable solution.
The critical low voltage threshold for a lead acid battery is around 10.5 volts for a 12V battery. For a 24V battery, it is 21.0 volts, and for a 48V battery, it is 42.0 volts. If the voltage drops below this level, the battery is at risk of being damaged and losing its capacity.

The nominal voltage of a lead acid battery is the voltage level that the battery is designed to operate at. For example, a 12-volt lead acid battery has a nominal voltage of 12 volts. However, the actual voltage of a lead acid battery can vary depending on its state of charge, temperature, and other factors.
The resting voltage of a 12V lead acid battery refers to the voltage measured when the battery is not under load (i.e., not connected to any circuits or devices). After a period of rest, a fully charged battery should have a resting voltage around 12.6 to 12.8 volts.
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?
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 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 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.
