Use quality batteries so as not to
damage the
light due to leaks or other self-destructive possibilities. Remove
batteries
when light will not be used for an extended period or if batteries are
discharged. When using Li-ion batteries Olight only recommends the use
of
"protected" batteries that limit charge and discharge.
Clean contacts, threads and O-rings of
the flashlights
with clean cloth from time to time when necessary. Should flickers or
doesn't
light up this is the most likely cause. If flashlight is used in wet
environment, lubricate O-rings frequently to maintain watertight seal.
After
prolonged exposure to moisture, the bezel, lamp, and batteries should be
removed, inspected, and cleaned if necessary.
