I hope I am being clear with my question.

With Lithium Ion's, if you leave them off the charger for a certain amount of time they will permanently lose a small percentage of their capacity, so these are more important to keep an eye on.
I'm not sure about Nickel Metal Hydride.

You coud just leave the camera on for a long time.
There's a danger in completely draining NiCad batteries. If the battery's a bit old and all the cells aren't equal then when the first cell completely discharges, the others will reverse charge it - which kills that cell (for the technically inclined, use Kirchoff's Law to calculate this effect). You'll hear a lot of numbers about how low to safely discharge NiCads, the quoted figures tend to be conservative - but that's probably not a bad idea - better than killing a battery. Metal Hydride batteries have a different chemistry and I haven't personally seen this effect in them.
