Charging Operation
(1) Screw the head of ST11 off and screw the CH11 onto the top of the torch body, ensuring the battery is still present in the ST11
(2) Connect the USB cord to the CH11 and to an appropriate power supply (laptop, wall charger, etc)
(3) Turn the tail switch of the ST11 ON
(4) The Charging Indicator Lights should illuminate to indicate power is present and show the status of the battery (Charging/Complete/Not inserted or inserted incorrectly)

Charging Time
The typical charging time for an 18650 2200mAh battery (from 0% charge) is approximately 5.4 hours from a standard USB connection.

Charging Indicator Lights
(1) While charging, the RED ‘Charging’ LED is illuminated.
(2) When complete the GREEN ‘COMPLETE’ LED is illuminated.
(3) If no battery is inserted or the torch tail switch is OFF the GREEN ‘COMPLETE’ LED is illuminated and the RED ‘CHARGING’ LED will flash.
(4) If the battery is inserted incorrectly the GREEN ‘COMPETE’ LED will pulsate.

Note: DO NOT continue to use the charger if no indicator LEDs are illuminated while the charger is inserted on the torch and power is present via USB. This may indicate a fault.

Note
1. Only one Li-ion 18650 battery with PCB protection can be recharged at a time.
2. If you do not intend to use the flashlight for a long period (i.e. a few months), remove the battery from the device and store separately to avoid leakage and damage to the torch and/or charger unit.
3. If storing the battery for long periods of time, charge and discharge the battery once every 3 months in order to prolong the lifespan of the battery.
4. Do not charge any other battery or poor quality battery using this charging unit or the Klarus ST11. Improper use may cause the battery to overheat, explode or cause serious damage to the battery or device it is contained in. This may also result in injury to persons or damage to property.
