No. not time based.  It charges to a specific ampreage.  So if
the charger is for 600mAh batteries (or whatever) and you put
in 1200mAh batteries it will charge till the back current load
is about 600mA and then trickle charge until removed.

Since the lithium and nickel battery carge cycles (time:charge) are
actually logarithmic as opposed to linear my example above will
result in a bettery that is only about 40% of what is considered
to be a "full charge".
