Tech Note | The Proper Charging of Stationary Lead-Acid …
With constant voltage charging there are two common charging voltage levels: Float charging is the normal charging method, ... For a lead-acid battery, the value above the OCV is approximately 0.12 volts. This "adder" voltage will vary very slightly (about +/- 0.02V) for different plate additives and construction, but it is a very good rule ...
Battery Impedance Size. Lead-acid batteries have a low impedance, therefore the ability to deliver high currents. Hence the large, short circuit current specified on battery datasheets, e.g., 2,500A for 12V 80 Ah battery. Typical impedance for a battery in the standby industry: 12V 80Ah VRLA battery = 0.003 Ω (3.0mΩ)
