The capacity of any battery is the total area under that curve, the area under the curve is integral, so if you know how to do your integrals and you’ve got the actual data, you can do an integral of it, but we would not do that. The other easier way to do it is to log the voltage and the current from the battery for a given load.
To measure capacitance, you'll need a digital multimeter, which you can pick up at your local hardware store. First, turn off the power to the capacitor, and connect a resistor across the terminals to drain the charge. Then, disconnect the capacitor, set the multimeter to measure capacitance, and press the REL button if your multimeter has one.
To calculate the capacity of a lead-acid battery, you need to know its reserve capacity (RC) and voltage. The reserve capacity is the number of minutes a fully charged battery can deliver a constant current of 25 amps at 80°F until its voltage drops below 10.5 volts. The formula for determining the capacity of a lead-acid battery is:
Obtain a reference impedance-capacity curve: Obtain or create a reference curve for your specific battery type that relates impedance to capacity. This can be done by performing controlled discharge tests at different SOCs and measuring the impedance at each SOC, or by referring to the battery’s datasheet.
