@Arthur-VU that is a definite no. Most multimeters pass a very small amount of current (from it's internal battery) between the leads to measure resistance based on the voltage drop of that (very small) current, they aren't meant to measure resistance across active supplies especially ones capable of delivery multiple amps like a battery. Basically, don't try to measure resistance across a voltage differential, it can be
very bad for the meter. I learn things like this the hard way, of course, oops
Google "how to test a battery internal resistance" there are plenty of videos and articles. The basics of it, is getting a known value resistor that can handle this task, then measuring the voltage of the battery without a load and then measuring the voltage of the battery across a load (the resistor), and plugging those numbers into a formula to get the internal resistance from the voltage drop.
