|Non-rechargeable Battery (Lithium)
Warning: *18650 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.
Unscrew the tail cap to insert the battery with the anode side (+) towards the light head, then screw the tail cap back on.
Intelligent Overheat Protection
The light will accumulate a lot of heat when used on High output level for extended periods. When the light reaches a temperature of 60°C or above, the light will automatically step down a few lumens to reduce the temperature. When the temperature drops below 60°C, it will then allow the user for the reselection of High mode.
Low-voltage Warning on the TK11 Tactical Flashlight
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, the light blinks 3 times every 5 minutes to remind you to recharge or replace the battery.
Note: This only works with Fenix ARB-L18 Series 18650 rechargeable Li-ion battery.
