Battery Powered Peltier (electrothermal) cooler?

[zeig]

I'm currently working on a project and need to power a Peltier (electrothermal) cooler. Is there any way i can get cold temperatures with a battery?I've provided a link to the component, they are around 12V and 77W and about 6A.

is there any electrical circuitry i could use off a basic battery or any way to power one of these? I need some cool temperatures on the cool side of the Peltier chip to cool some water, I'll have a heat-sink and fan attached to the hot side to increase efficiency.

Thanks~

The math is quite straight-forward; 77W/12V = 6.4A.

That means that you need a minimum of a car battery if you intend to run it for any length of time. AA's could last about 15 min at that level of current.
