Choosing a battery for this project was an issue of weight vs. cost. If cost was not an issue i'd be throwing a Li-Ion pack on here and it wouldn't be a issue. It's much the case that good priced rechargeable batteries are low in amps, so they discharge quickly. My suggestions for this project are the following:

A few D (8000mAh) NiMh batteries equaling 12v (Slightly Expensive but will last quite a while)
or
12v Lead Acid (Heavy as hell, really cheap)
or
2 Lantern Batteries at 6v each (Not Rechargeable, boo)

for this project's longevity, go with a rechargeable option. If you have a lot of amps you could also run a car horn or a small sound system.

Some of the 6-Volt lantern batteries have 4 non-rechargeable D size batteries inside them, particularly the Energizer metal jacket lantern batteries...I converted one to rechargeable once, by taking the old D cells out, and putting new, rechargeable ones in...
