It means just that, the battery has been drained, has no power left. W/o battery the engine can't crank, w/o cranking it won't fire, w/o fire it won't run.
Yep, will not start.
A car battery should not be "cycled" as in fully discharged and then recharged. Such a cycling would quickly destroy this kind of battery. A car battery is discharged slightly when you start your car, then it is recharged again when you drive your car. Proper charging whilst running car engine is good for the battery. A normal car-battery (Lead-acid) can last for many years if not "cycled". Never discharge battery more than 50%. How often you actually need to recharge your battery depends on how it is used.

no the car wont start because the battery is dead, it was discharged by running it and not being recarged by the alt
Could be a battery problem, discharged, dead or dirty/loose battery connections.
An auto battery does emit hydrogen gas when it is being charged or discharged but it does not contain gas per se.
Either your battery is discharged or dead. caused from 1) alternator not working or 2) Battery life span is over - recharge battery at Any auto parts store . if not recharging . replace battery .
On an automobile battery it sure does. Each time the battery is discharged the life is shortened. On a deed cell marine or golf cart battery this is not the case.
Usually from being discharged in below freezing weather. The water will freeze in a dead battery, expand, & swell the battery. This won't occur with a fully charged battery.
Discharged battery possibly or trouble with starter.
You'll need an external power source (such as a battery charger or another car hooked to battery cables) in order to start your vehicle. A battery which is truly depleted - not just discharged - will not take a charge from the alternator, and will need to be replaced.
Maybe there is a short to earth somewhere in the car so the battery is being permanently discharged.
