It depends on the leakage current of the device or power.
A 12V, 2.2 Ah battery can supply:
12V 2.2 A * 1 h = 26.4 watts for 1 hour or
12V * 1A * 2.2h = 12 watts for 2.2 hours, or
12V * 0.5 * 4.4h = 6 watts for 4.4 hours
12V * 132 * 1 minute = 1584 watts for 1 minute.
etc.
Put an ammeter between the device and battery, and then multiply this reading (in amperes) of 12V, and add 10% loss in the conversion of AC into DC for your horsepower.
Specify power requirements for the battery is not based supply available. Most power supplies are rated at a certain voltage and current levels then the chances are you have a power supply 12Vdc to 120Vac, that can deliver the load current.
.. You can try, hmmm http://www.needbattery.com
