All of those in series would give you 12 volts, but assuming 1800 milliamp-hours (mAh) it would only power the lights for 1.2 continuous hours.
I found this quote "AA alkaline cells have their capacity rated at only 25mA and an end voltage of only 0.8V per cell. At 500mA their capacity is half.
At 0.5A and 1A their voltage quickly drops like a rock."

So you may have voltage problems with 1.5 amps flowing through those AA's.
Check out something like BigSlowTarget suggests, for example: http://www.amazon.com/Rechargeable-Sealed-Lead-Acid-Battery/dp/B000BPCUXO
If you look at the description, it says it's only "3.5 x 2.8 x 4.1 inches ; 3.9 pounds", which is comparable to a block of AA's. The SLA batteries should be rechargeable too, but you'd need to buy a charger for them.
20W x 3 hours = 60Wh
So you need a 12v battery rated at 5Ah I guess....

Let me see what it costs, if it's not too bad I'll save you the trouble. You can buy these on-line for $15 with free shipping , so I want to make sure we can keep the shipping under that, otherwise it's cheaper for you to just buy a new one. ;-)
