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 load conditions applied to a lead-acid battery can also impact its voltage. When a load is connected to the battery, the voltage tends to drop due to internal resistance and the energy being drawn from the battery. Similarly, removing a load can cause the voltage to rise.

When a lead–acid battery loses water, its acid concentration increases, increasing the corrosion rate of the plates significantly. AGM cells already have a high acid content in an attempt to lower the water loss rate and increase standby voltage, and this brings about shorter life compared to a lead–antimony flooded battery. If the open ...
