Why can''t I measure the internal resistance of a car battery
If you do the change in voltage due to 1 Amp load test: Assuming 10 milliohm resistance (above post), loading the battery with a 12 ohm resistor for 1 Amp current should change the voltage at the battery terminals by 10 mV.--To measure < 10 mV change at approximately 12 V requires at least 4-1/2 digits in the DVM.
