How to measure internal resistance of a battery
VI = Voltage across Internal Resistor. VI = I · RI. 0.054V = 0.3615A · RI. RI = 0.149Ω. From this, we can see the internal resistance 0.149Ω for the AA battery. Is internal resistance a factor in performance? The capacity of a battery is useless if it can''t transfer the stored energy; a battery must also have a lower internal resistance.

9V battery and resistor are connected in series
$begingroup$ Also, OP, the reason you might measure 9 or just above 9 on a multimeter on a real 9V PP3 battery, is because while the internal resistance is still there, the multimeter has a much, much larger resistance (in effect, to absorb as much voltage* as it can to cancel out the effect of any potential divider occuring) so the multimeter registers …
21.2 Electromotive Force: Terminal Voltage – College Physics
There are two voltage sources when a battery charger is used. Voltage sources connected in series are relatively simple. When voltage sources are in series, their internal resistances add and their emfs add algebraically. (See Figure 8.) Series connections of voltage sources are common—for example, in flashlights, toys, and other appliances.
