Understanding battery capacity: Ah is not A

hey, great posts. Question. I'm dealing with larger loads, should the math stay the same. I'm looking at an 18a 12v load. I'd need it to last 1/2hr, plus two hours for electronics (.25amps) Is it safe to say an 18ah sealed led acid battery would work for me? Or should I go with a larger ah rating? I'm just want to verify that i'm not missing something as the load scales up.
thanks
