yes
and you can confirm this by measuring battery voltage, which will be above 0 volts.
the danger w unprotected ICR chemistry is if discharged below 2.5v, they can overheat during the next recharge… so… charge under adult supervision… do NOT leave on charger unattended overnight
other chemistries such as IMR and INR are less dangerous when overdischarged.
so, we need to learn if the battery is unprotected ICR, as that is the risky one, IF overdischarged, and IF it overheats upon recharging
but these little twisty 10180 lights dont come on at maximum when you press the head after unscrewing, they come on at minimum… so instead of draining the battery in 15 minutes, it can go for several hours…
in any case, if the light gets dim, recharge it on a fireproof surface, and under your supervision… touch the light after a few minutes on charge, if it is not too hot to touch, not smoking, and not venting with fire…
dont worry, be happy
yes
and you can confirm this by measuring battery voltage, which will read 0 volts. Total Zero!
that is because the protection circuit on the battery itself has tripped
if you put it on a charger for a few seconds and then measure the battery, it will be more than 0 volts. Meaning the protection circuit has been reset.
it is possible for the light to get dim before a protection circuit in the battery is triggered
it is also possible to trigger a protection circuit immediately, when using high mode with a depleted cell, that will just blow its fuse when asked to provide maximum power
Ive never heard of a fire from a 10180 battery… try not to worry
enjoy your cute little light

areas for further investigation
learn how to access the battery in your little Olight, so you can use a DMM to check voltages.
is the battery unprotected ICR (most vulnerable to overheating on recharge after overdischarge)
or unprotected IMR or INR (relatively safer, best to recharge promptly if overdischarged, monitor heat during charging, as with ICR)
do you want to buy a protected Klarus 10180?
is protection important in these lights?
does the Klarus cell fit the Olight? (protected cells tend to be a little longer)
