Maybe I wasted a few bucks!

That is, they step up the supply from 12 Volts to a higher voltage which is then regulated and supplied to the computer.
The other alternative is to buy a 240 Volt inverter which runs from 12 Volts and then use your existing mains power supply.
Unfortunately both those solutions tend to chew through the battery fairly quickly so your deep-cycle battery would need to be a decent capacity.
Given that you only get some 1.5 hours out of your laptop battery I'm guessing it's possibly a reasonably powerful device?
Perhaps a more modest computer such as a small, cheap and possibly second-hand netbook might be a solution?
