Lead Acid Battery Voltage Chart: The Voltage Level Differences
Most solar charge controllers are designed to work with 12-volt, 24-volt, or 48-volt battery systems. The voltage of your battery system will depend on the size of your solar power system and the amount of energy you need to store. The lead-acid battery voltage chart shows the different states of charge for 12-volt, 24-volt, and 48-volt batteries.

But if the load is a constant current load (like a battery discharge testing machine) then the load current, naturally, stays constant. If the load is a constant power load, like a switching power converter itself loaded with a resistive load, then the output current could actually increase as the battery is discharged.

If you only have periodic voltage measurements and the load current is small, you can approximate the state of charge of the battery with a SOC-OCV (state of charge - open circuit voltage) graph. You can probably find this graph for whatever chemistry battery you have and find the SOC that corresponds to a given voltage.

In fact, the terminal voltage can change dramatically as a cell goes through charge and discharge cycles. The ''nominal voltage'' is what the chemists tell us the cell should produce with zero current flowing. Whenever a current is drawn from a cell or pushed into a cell, the voltage changes, even when the current is that drawn by a voltmeter.
