Yes, they can be 12v....for the smaller units. Anything over 500va is generally going to have two batteries in series to create 24v, four batteries to create 48v, etc.
Now, as for the time that they will run, many of the larger units have extended battery capabilities, allowing them to run for longer periods of time. I have several in the racks at work that are (intentionally) oversized for the load in the rack. They will run for 30-45 minutes or more easily without overheating. Granted, small load on a big unit. The only reason they stop running is because the battery runs out during a power outage.
Will you be able to do what you want for $100 though? Probably not.
