*Li-ion batteries are powerful cells designed for commercial applications and must be treated
with caution and handled with care. Quality batteries with circuit protection will reduce the
potential for combustion or explosion but cell damage or short circuiting are potential risks the
user assumes.
Battery Replacement
Unscrew the tail cap to insert the battery with the anode side (+) towards the light head, then
screw the tail cap back on.
Usage and Maintenance
Disassembling the sealed head can cause damage to the light and will void the warranty.
Fenix recommends using excellent quality battery. If the light will not be used for an
extended period, remove the battery, or the light could be damaged by electrolyte leakage
or battery explosion.
Continuous usage at Turbo brightness level in hot or poor heat dissipation environment, the
light may activate overheat protection or light beam trembling. To maintain normal usage,
please lower brightness level to cool down the flashlight.
Long-term use can result in O-ring wear. To maintain a proper watertight seal, replace the
ring with an approved spare.
Periodic cleaning of the battery contacts improves the lamp's performance as dirty contacts
may cause the lamp to flicker, shine intermittently or even fail to illuminate for the following
reasons:
A: The battery needs replacing.
Solution: Replace battery (Ensure battery is inserted according to the manufacturer's
specifications).
B: The threads, PCB board contact or other contacts are dirty.
Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol.
If the above methods don't work, please refer to the warranty policy before contacting your
authorized distributor.
