How to Measure Internal Resistance in a Lead Acid Battery: A …
After measuring the internal resistance of your lead acid battery, you will have a numerical value that indicates the resistance of the battery''s internal components. This value can be used to determine the state of health of the battery.
[SOLVED]
The internal resistance forms a voltage divider with the load. If the voltage is 12V with no load and drops to 6V when the load is 1 ohm then the internal resistance is 1 ohm. But the voltage will not drop that low, maybe it drops to 10V so the missing 2V has a current of 10A and the internal resistance is 2V/10A= 0.2 ohms.
