Ok to leave Battery charger plugged in indefinitely after green light has gone off?

So I just got hold of a few of these new battery chargers from Apple and I'm just wondering if these are meant to stay plugged in the wall, even after the green light goes off. Does the light going off mean that the batteries will no longer draw power from the power outlet and that it is safe to assume power will continue to be consumed? Or is it preferred that I plug and unplug the charger only when needed to avoid any, unnecessary, extra power consumption?

Anyone have an idea? Much appreciated, thanks.

Yes, it's fine to leave it plugged in. It stops charging when the battery is fully charged. This should answer most, if not all, of your battery questions: Apple Notebook Battery FAQ

Thanks. Great info there, but if I'm not mistaken, is that resource just specifically for Mac laptop batteries? I was speaking of the new Battery charger accessory that Apple just released.

I missed that. Your answer is here:

But the Apple Battery Charger senses when its batteries are done charging and automatically reduces the amount of power it needs.

Thanks to an intelligent power management system, the Apple Battery Charger uses less power once your batteries are fully charged,
