I''ve read this new (20230 study about desulfating flooded lead acid batteries with just high voltage DC charge. It is very interesting as they tested just overvoltage on desulfating flooded lead acid. Many a company sells pulse desulfators, but if all we need is a bench power supply - that would be a great discovery.
Lead-acid batteries are known for their nominal voltage, which is usually 2 volts per cell. A typical lead-acid battery consists of multiple cells connected in series to achieve the desired voltage level. The voltage of a lead-acid battery can vary with respect to its state of charge, temperature, and load conditions.
At room temperature, the voltage of a fully charged lead-acid battery is around 12.6 volts. The voltage of a lead-acid battery varies with temperature, decreasing as the temperature decreases and increasing as the temperature increases.
To use a Lead Acid Battery Voltage Chart, locate the specific battery model you are using on the chart. Then, based on the voltage reading of your battery, you can determine its state of charge and make informed decisions about its usage or charging requirements.
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?
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.
