I did find one chart that said it draws 7.2 amps on the lowest speed.
7.2 amps you might get two hours run time out of that battery.
Since it lists Cold Cranking Amps it is most likely a STARTING battery. If that is the case then discharging to 50% not recommended.
You might look for AGM batteries (This is one of the rare exceptions where I recommend AGM's cause they do not mind being upside down). You can find them in assorted sizes at Batteries PLUS stores all over the country.. Look for a true DEEP CYCLE, and buy two of 'em.
