Car battery voltage chart — State of charge
You can check your car battery start of charge using a voltmeter, thermometer and this car battery voltage chart.
Car battery voltage must be above 12.2 volts to operate properly
If the voltage isn’t within spec, perform a voltage drop test to determine the condition of the terminal/post connection.
Computers can’t operate at voltages of 9.6 or lower.
