I think that it'd be more convienient to think of aura like a battery. Some contain more than enough to be used for centuries, some contain only the miniscule amount required to activate an ability, some take ages to recharge, others seconds.

I see it like this for mainly variance's sake. It'd be interesting to see how a different auras work and the special dynamics that they entail.
