Battery powered server fan

So I need to power this Delta Server Fan with a battery: http://www.newegg.com/Product/Product.aspx?Item=N82E16835213001

 

Which requires 12V and for full speed it recommends 2.45 amps.

 

Does anyone have an idea of how to power this with a battery without using a car battery or power supply?

 

If i were to do 8 AA batteries for 12v, it would have too much amps (yes i know batteries are in milliamp hours). If i do 1 9V battery, not enough power.

Well if you do it correctly you should be able to set up your batteries in series to achieve the amps you require, albeit the life span of your batteries will be a bit short.

You could use the battery from a UPS:

Depends on how much time do you need the fan to work.

Now someone correct me if I'm wrong here, but I do not believe it will matter if you have 8 AA batteries and it provides "too much amps". With a power supply (directly supplied DC or AC voltage with constant power), you cannot draw too many amps, because your device will draw as many amps as it requires, up to the limit of the power source. Now, a Fan does not include any power circuitry, so I don't know how this might change the scenario.
