Potlife of Activated Base??

Just curious what the potlife would be on a quart of activated base with a cap of hardner. I just cringe when I have have a cup left over and feel like its a complete waste.
 
Typically the paint companies say 8 hours. I have used mixed basecoat with activator all the way out to 48 hours without issue. Usually I will try to mix it with some "fresh" stuff. I can't say it was okay, but nothing bad has happened either.
