Measure voltage and current to determine battery loss
Methods of SoC determination of lead acid battery
In case of ohmic polarization (internal resistance) determination, an alternating current I AC of about 1 kHz applied to the battery terminals can be used. In the 1 kHz range, the imaginary component of the battery impedance is close to zero and the real component is minimal. ...
3 Ways to Measure Voltage
Set the range to one level above the voltage you plan to measure, so if you are measuring a 12v battery, turn the dial to 20v to get an accurate reading. X Research source If you choose a range that is too low for your test, the multimeter will display a "1", indicating that you need to choose a higher range.
