*18350 Li-ion batteries are powerful cells designed for commercial applications and must be treated with caution and handled with care. Using low-quality batteries or mishandling batteries (such as short-circuiting or overheating) could lead to combustion and jeopardize the safety of users and property. Any adverse effects resulting from the use of low-quality batteries are not covered by any Fenix warranty or liability. Using quality batteries with circuit protection will reduce the potential for combustion or explosion.

*CR123A batteries should be reserved for emergency use only. Do not recharge while using a CR123A battery! Using a CR123A battery will reduce available output levels and shorten runtime. For optimal performance, it is recommended to use a Fenix ARB-L18-1600 battery.

Battery Replacement

Usage and Maintenance

• Disassembling the sealed head can cause damage to the lamp and will void the warranty.
• Fenix recommends using an excellent quality battery.

• If the lamp will not be used for an extended period, remove the battery, or the lamp could be damaged by electrolyte leakage.

• Take out the battery to prevent accidental activation during storage or transportation.

• Long-term use can result in O-ring wear. To maintain a proper water seal, replace the O-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: Poor battery level.

  Solution: Recharge or replace the battery.

  B: The contact or contact point of the battery or headlamp is dirty.

  Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol.

If the above methods don't work, please contact the distributor.
