9V Battery Current Range
For example, a freshly made "Zeus 9V alkaline battery" can deliver 2.5 A of current (9.5V with 3.9 Ω load for 0.3s): With voltage drop of just 0.1 V, this make the battery ESR of 0.1/2.5 = 0.04 Ω. SHorting this battery might create quite a peak of current. The datasheet also shows "service output" for this battery under several scenarios.

Measuring MAX current of a battery 9 volts, AAA, AA
9 volts is at 25 mA, is 25mA the max current out of a 9 volt battery? No, 25mA is the safe current for maximum efficiency of the battery. 1.5 volts is 4.0mA, is 4.0mA the max current out of a 1.5 volt battery? No, 4mA is the safe current for maximum efficiency of the battery. Why are they testing a 9 volt batterys current output at 25ma?
Batteries
That is, the 9 Volt battery would need to be tested by having it supply . 1/20th of its rated capacity -- this would be 50 milliamps -- for twenty hours. If it were drained faster, as in a one-hour test or in a high-current application, the effective capacity would be much less. ... along with the maximum voltage and current. Lead acid cells ...

The ultimate guide to understanding 9 volt battery
Nearly every household electronic device uses batteries, and most small devices possess a 9 volt battery to operate. 9-volt batteries were initially invented in the 40s for use in World War II radios and clocks in tanks. But now, it highly demands batteries in various applications to provide suitable energy to electronic devices like smoke alarms, …
batteries
After a lot of research and experimentation I have come to learn that the sentence "This is a 1.5V, 2800mAh battery" is entirely a lie. (i.e., the potential difference between the terminals of a battery changes over time and the shape of the graph is dependent on battery chemistry, ambient temperature and current draw, as is the useful …

Maximum power/current for a battery?
5. How can I determine the maximum power/current for a specific battery? The maximum power/current for a battery is typically listed on its datasheet or packaging. It can also be calculated by multiplying the battery''s voltage by its maximum current output. It is important to note that the maximum power/current may vary …
How much current can a 9V battery supply? Let''s test it!
In this video I conduct a scientific test to find out how much current different batteries can supply under maximum load. This will tell you which battery t...
multimeter
If the current is too high it will blow the fuse on the multimeter, or blow up the battery. Wikipedia says the Energiser AA battery has an internal resistance of about 0.15R at room temperature. This gives around 10A current. However, the internal resistance of the multimeter may now have an effect, reducing the current.
9 (7.4v) Li-ion rechargeable battery maximium drain current?
So, I would say that the discharge rate of about 55 mA is the right one for this battery. You probably can get more, 200-500 mA, but the capacity will degrade. EDIT: From some reviewers, this "9-V" battery is the best, made by iPowerUS. Here are test data for it. Discharge current is 500 mA max. Internal resistance - under 450 mOhms.
Nine-volt battery
The nine-volt battery, or 9-volt battery, is an electric battery that supplies a nominal voltage of 9 volts. Actual voltage measures 7.2 to 9.6 volts, depending on battery chemistry. …
9V battery versus 6xAA batteries
To calculate max allowable internal resistance of the 9v battery for your application, first, find the critical battery voltage at which the normal operation will halt (5V in our case) and the current o/p required in that state to …
