The math is right, but charging batteries ain't an exact science...So add like 20% to your final time and I'd say you're fine with 13 to 14 minutes.
As far as the AA ratings...I haven't tested a single Alkaline AA, but I'd say 1250mA would be about right.
Let's use the classic Water to Electricity comparison, hopefully this helps with understanding what's going on...
If Electricty was water; Current (mA) would be the volume or amount of water flowing and Voltage would be the pressure or how fast it was flowing at.
For comparison sake, using an AC Adapter at 3v/500mA would be like getting shot by one of those big Super Soaker guns...Whereas using a 4xAA Alkaline battery pack would be like getting shot by a Firehose...They'll both get you wet, but one hurts less...ESPECIALLY over time.
So, the hog is right in saying that Voltage matters (somewhat)...But you need to be careful with the Current
