Probably so, look to find it's rated watts per hour and divide that number by 12 to get the current. Then multiple that by the number of hours you will use it to get how much the battery will discharge.
120 watts per hour / 12 = 10 amps
10 X 8 = 80 amps discharged.
Your battery may be 550 CCA so it will be down to 470 CCA.
Older battery's never reach full recharge.
