yes, actually, it'll stop higher than that, depending on the LED you are
using..
Make sure you have a ballast resistor in series with it, don't
connect it directly.. The ballast R depends on the voltage your NiMHs are..
Most LED flashlights have "usual white LEDs", which are blue ones with
a phosphor that converts much but not all of the blue light to a broadband
yellowish light. The yellowish light combines with the unconverted part
of the blue light to form white or whitish light.
These LEDs do not significantly conduct at any voltage normally produced
by a single NiMH cell. An LED flashlight that uses a single NiMH cell has
a boost converter circuit. Chances are fairly high that the boost
converter circuit will not shut off when the cell voltage decreases to .9
volt.
On the other hand, there are many 3-cell white LED flashlights. If you
put in 3 equally-charged NiMH cells, chances are "reasonably good" that
they are "discharged safely" once the flashlight runs them down to being
"noticeably dim" or "almost uselessly dim". Don't run the cells down to
"completely uselessly dim" or "dim as a glowing cigarette" or "completely
out".
One more thing - if an NiMH or NiCd cell, after removing it from the
device that discharged it, still has voltage at least .5 volt and in the
proper polarity, then in my experience any overdischarge damage is very
negligible. My experience is that "overdischarge damage" mostly occurs
from either "discharging past zero" ("reverse charge") or prolonged
storage with zero charge.
