Other Types Of Lead Acid Batteries Have Varying Ideal.
Constant current discharge curves for a 550 ah lead acid battery at different discharge rates, with a limiting voltage of 1.85v per cell (mack, 1979). The table below summarizes the float voltage ranges for 12v and 24v batteries. Do remember that battery voltage readings are temperature dependent.
At Higher Temperatures (Over 85 Degrees F) This Should Be Reduced To About 2.10 Volts Per Cell.
Secondly pulling voltage down to less than 50% remaining capacity permanently devalues the battery. But in fact far higher rates are acceptable in many cases if due care is taken. Sealed/flooded lead acid battery voltage gel battery voltage agm battery voltage;
Can I Have A Mathematical Relationship Between Soc And Open Circuit Voltage Of A Lead Acid Battery?
Minimum voltage anything above 2.15 volts per cell will charge a lead acid battery, this is the voltage of the basic chemistry. If it can put out more current than the battery can take then the battery may overheat. So between 50f and 80f could have a 10% difference in charge state.
A 10A Load On A 100Ah 20 Hour Rated Battery Would Therefore Be A 0.1C Discharge Rate, A 0.2C Discharge Rate On A 200Ah Would Be 40A And So On.
This also means than nothing below 2.15 volts per cell will do any charging (12.9v for a 12v battery) however, most of the time a higher voltage than this is used because it forces the charging reaction at a higher rate. 14.7v is higher than you'd usually meet but around 14.4v is common for topping mode charging which is used to equalise charge in series connected cells. Depending on the state of charge (soc), the cell may temporarily be lower after discharge than the applied voltage.
