I was probably not very clear. I meant removing them when the camera
stops working, I'd hope modern cameras stop at an appropriate point.

i didn't mean discharge to zero, and they do stop ahead of that.

the point is that lion batteries will last longer with many partial
discharges than fewer deep discharges.

I have recently read, in conjunction with suspected battery problems
on a third generation iPad, that it is desirable to discharge to zero
once a month or so. The explanation is that it allows battery
management system in the iPad to recalibrate itself. The explanatikon
was minimal and I didn't understand it. Does it make sense, even if
only in terms of iPads?

it makes sense. what part did you not understand?

The part where it contradicts your advice "discharging them fully is a
very bad idea... "

however, it doesn't need to be done anywhere near monthly and isn't
specific to apple products.

it also has nothing to do with what's best for long term battery life.
