or better yet how many ampres can I pull from a single 1.5v AA battery?

You can readily get 50 mA from a single AA alkaline cell.
The projected life at that current is about 40 hours.
Here is a link to some Duracell info...

(I have no connection of any kind with Duracell, but their product is presumably representative.)

A single healthy alkaline AA battery can deliver 10 amps in short bursts 10-20 seconds. Two in parallel will deliver twice this much.
This is 400 times your original 50 ma target. You will not get much life at this high discharge rate because the battery will heat enough to produce internal damage if left connected longer for than about 10 seconds between cycles.
Ni cad batteries have the highest short circuit current available. They can produce 5 to 10 times that of alkaline but suffer the same overheating problems in high current drains. Nimh have higher overall capacity per size but short circuit current that is in between alkaline and ni cads.

One. If you put a 1.5 volt battery across a resistive load it will produce 50 milliamperes of current. However as the battery discharges current, the voltage will droop, and the corresponding current flow will decrease. Since a typical AA battery doesn't have a large capacity, the current will be 50 milliamps only for an instant.
The following link may shed some more light on the subject.

including yet another battery in parallel received't provide you with any more beneficial potential (wattage) because the Resistance of your starter stayed the same and your voltage remained the same. And... potential(watts) = modern (amps) X Resistance (ohms). All you do hooking those up in parallel is advance your storage skill. (amp hours) In different words you doubled the era of time it takes to run your battery down. if you're not any further getting sufficient cranking amps there could be another difficulty.. Like cables are too lengthy or undesirable connections. Be very careful taking area in round with this idea of more beneficial batteries. The solutions above are incorrect for the most area an my reason complications extraordinarily the tongue remedy.........

The Duracell Company posted information about the standard Duracell battery on the Internet. This information stated that their battery had a capacity of 2850 milliamp-hours, when drained at 26 milliamperes on a load of 43 ohms.(5)

to be perfectly honest with you i (and i doubt anyone) has ever measured the amp load of a battery (except for car batteries).
since a battery of that size would be measured in milliamps
it would be to small to measure. and would be in the design of the device being powered as to the rating in terms of voltage.
