If 4 batteries are connected in parallel and NO LOADS are connected to it, the Terminal Voltage = 9 volts.
If loads are connected to battery termials:
For ideal case (zero internal resistance which is almost impossible), the terminal voltage = 9 volts.
If the internal resistance of each battery is R, the equivalent resistance of 4 parallel batteries = 1/[1/R + 1/R + 1/R + 1/R] = R/4, and if the connected load draws a current of I from the battery, the available
BATTERY TERMINAL VOLTAGE = (9 - IR/4) volts

assuming no voltage droop when under load, the voltage would be 9 volts. In a parralles circuit voltage is common. In a series circuit current in common.

That would be 9 volts. If you hook them up in series it would be 36 votls.

9 Volts....
If they were connected in series...that is negative to positive...the voltage would add to 36..

offcourse 9 volts.

Just nine. This is done so you can draw more current.
