Deep cycle battery are extremely heavy. I doubt that you would want to haul that much weight around with you just for a cooler.
I would believe that the alternator on the GL1800 would provide enough power to run the cooler but check what the amperage is and be sure. Of course you could run directly off the battery if needed, to protect your bike's wiring harness. Nothing is so important than to protect the wiring harness. Just be careful!
Hope this helps.
