A 120 aH battery will be pretty dead after 80 aH have been drawn. 80 aH in 24 hours is 3.333 amperes, which ain't much (a little less than two typical 12v lamps). So if it'll run a day on a 120 aH battery it seems to me it's not such a hog.

I should qualify I unplugged it at night other wise it would have been dead in the middle of the night it would not make 24 hours even on a good day more like maybe 15 hours.
