BATTERY SPECIFICATIONS
| Type | Dimensions | Nominal Voltage | Recommended |
| Rechargeable Li-ion Battery | 21700* | 3.6V | Fenix ARB-L21 Series |
| Rechargeable Li-ion Battery | 18650 | 3.6V | Fenix ARB-L18 Series |
Warning: The Fenix dedicated ALF-18 battery holder must be used together when using 18650 Li-ion batter.
*18650 and 21700 Li-ion batteries are powerful cells designed for commercial applications and must be treated with caution and handled with care. Only use 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.
Low-voltage Warning
When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level until Low output is reached. When this happens in Low output mode, the indicator in the mid of the functional side switch will flash red to remind you to recharge or replace the battery. To ensure normal use, the flashlight will not turn off automatically and will work till the battery runs out completely.
Note: This only works with Fenix ARB-L21 Series 21700 rechargeable Li-ion battery.
Intelligent Protection of TK30 Laser Flashlight
The light will accumulate a lot of heat when used on Turbo output level for extended periods. When the light reaches a temperature of 65°C or above, the light will automatically step down by a few lumens to reduce temperature. When the temperature is reduced, the output will gradually return.
USAGE AND MAINTENANCE
- Disassembling the sealed head can cause damage to the light and will void the warranty.
- Fenix recommends only using quality battery with proper built-in protections.
- 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.
- The included battery needs to be charged when it is near depletion. Please immediately charge the battery when it is depleted without concern of affecting the Li-ion It has no memory effect.
- Unscrew the tail cap half a turn or 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 ring with an approved spare (included) when damaged．
- 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 contact your authorized distributor.
