You have to have more info then that.
What kind of load are you putting on it.
The formula is I=E/R
I=current in amps
E=voltage (9 in your case)
so you have to know "R"
Technically on paper the battery will attempt
to produce whatever amps the formula calls for.
But in reality it doesn't have the stored power
to give lets say 20amps.
it will TRY to give 20 amps but if it did it would
only last for a millisecond before the battery is dead.

Keep in mind the cutoff voltage of the specs. Down to 5 volts? That's getting pretty weak for most applications. Need to be rated at down to 8 volts or so I'm thinking.

Batteries are rated in amp hours. A battery rated at 500 Mah will supply a current of 500 mA for approximately 1 hour before it is expended. Or 250 mA for two hours, etc.

Raven E's answer would be correct if you had a load and resistance known or you wanted to find the internal resistance of the battery.
Rechargeable is around 175 to 200 mAhr

9v Battery Amps

Batteries are rated in amp/hours, a 9v has between 500 and 800 mAh(milliamphours).

I'm leaning more toward around 500 milliamps.
