Stop in for a cup of coffee

So someone with better electrical understanding double check me.

According to research, a standard car battery in group 34 has a max amp hour of 75 hours. so to figure out how long that battery will last at max, you'd take the Amp hours divided the amp charge draw right?
75 hours at 1 amp draw, or 1 hour at 75 amps. Do the math.

you can leave it parked the same length of time as a newer vehicle. Maybe 30 days max.

dont go overthinking this, as you still need some battery left to start car.
