How much current can you pull safely off a standard AAA battery?
The maximum current depends very much on the chemistry of the battery. The capacity of the three main (no Lithium) batteries is approximately: Zinc-Carbon: 540mAh; Alkaline: ~1000mAh; NiMH: ~900mAh; The current limit and capacity of any specific battery can be found in its datasheet. For instance, the Duracell MN2400 has the following nice graph:

What is a safe max. discharge rate for a 12V lead acid battery?
Max Discharge Current (7 Min.) = 7.5 A; Max Short-Duration Discharge Current (10 Sec.) = 25.0 A; This means you should expect, at a discharge rate of 2.2 A, that the battery would have a nominal capacity (down to 9 V) between 1.13 Ah and 1.5 Ah, giving you between 15 minutes and 1 hour runtime.
Wire Size Chart and Maximum Amp Ratings
Electrical current is measured in amps. Each wire size, or wire gauge (AWG), has a maximum current limit that a wire can handle before damage occurs. It is important to pick the correct size of wire so that the wire doesn''t overheat. The number of devices connected to the circuit usually determines how much current will flow through the wire.
