Well if you take the voltage with the car off (12.18V) and subtract the lowest voltage seen when it starts (10.21V) and you assume the starting motor draws about 90A, you can roughly calculate an internal resistance of 0.022 ohms which is typical.
A very strange video.. I have never heard a car start, only an engine? There was no mention of what the 3 meter readings related to, or if there were correct. Lastly, why was the video titled battery internal resistance?
The title was internal resistance.
This is a real wait of time video , it has nothing to do with the internal resistance of a car battery

Assuming is for asses
And the resistance is?
Since you started, the engine, charged it up for 10 seconds and shut it back off the voltage will be under what you started with.
Very good, Louis. Short, but pointless.
This is voltage testing, not internal resistance. Title is completely wrong.

Might wanna rename the vid "car battery resting/starting/running voltage".
Why do you call your video "resistance" when all you did was measure the voltage. You will get a lot of thumbs down for this.
