Battery Specifications

Ni-MH Battery AAA 1.2V Recommended ✓✓

Warning: When the voltage level drops below a preset level, the flashlight is programmed to downshift to a lower brightness level until Low output is reached. To ensure normal use, the flashlight will not turn off automatically and will work till the battery runs out completely.

Time-limited Downshift

The light will accumulate a lot of heat when used on High output level for extended periods. When the light has been used on High for 3 minutes, the light will automatically step down by a few lumens until 60 lumens is reached to reduce the temperature. High mode can be reselected.

Usage and Maintenance

  • Disassembling the sealed head can cause damage to the light and will void the warranty .
  • Fenix recommends using excellent quality batteries.
  • Fenix strongly recommends using high-performance Ni-MH rechargeable batteries to get the most out of this light. Alkaline batteries will reduce the runtime relatively.
  • 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.
  • Long-term use can result in 0-ring wear. To maintain a proper water 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.
    : Replace battery (Ensure battery is inserted according to the manufacturer’s specifications).
    B: The threads, PCB board contact or other contacts are dirty.
    : Clean the contact points with a cotton swab soaked in rubbing alcohol.

If the above methods don’t work, please contact your authorized distributor.
