Output & Runtime
Power Tips
1. With the light on, the blue LED built into the switch will flash once
every two seconds when battery power levels reach 50%. The blue LED
will flash quickly when battery power is close to depletion
2. After battery installation or with the mode switch being pressed when
the light is off, the blue LED built into the switch will blink to indicate
remaining battery power. The power indicators will blink three times
when power levels are above 50%; twice when power levels are below
50%; and once when battery power is close to depletion.
Changing Batteries
Batteries should be replaced when any of the following occurs: The
power indicator blinks rapidly, output appears to be dim or the flashlight
becomes unresponsive.
Maintenance
Every 6 months, threads should be wiped with a clean cloth followed by
a thin coating of silicon-based lubricant.

Tips
Inserting batteries in a dark environment: Two of the four battery slots in
the EA41’s battery compartment feature grooves indicating that batteries
should be inserted with the negative (-) ends facing forward, while the two
slots with no grooves require the batteries to be inserted with the positive
(+) ends facing forward. In this way, batteries can be inserted correctly
through tactile feedback alone.
After loading the batteries, the power indicator light will blink to indicate
the battery power. Please refer to the “Power Tips” section of this manual
for details.
WARNING
1. Insert batteries using the image on the inside of the battery
compartment as a reference.
2. Do not mix rechargeable and non-rechargeable batteries.
3. Do not mix batteries of different types/brands.

brightness levels of ultra-low, low, medium, high and turbo. This mode
provides an intelligent memory function to ensure direct access to the
setting last used when reactivated.
Instant ultra-low/turbo
Instant ultra-low: with the light off, press the on/off switch for more than
one second to create ultra-low output of 1 lumen;
Instant turbo: with the light off, press the mode switch for more than
one sencond to create turbo output of 960 lumens.
NOTE:
The EA41 will lower its output lumens after 20 minutes of use to
prevent overheating and preserve battery longevity.
Special modes (Strobe/Location/SOS)
With the light on, press the mode switch for more than one second to
enter strobe mode. To cycle through all three modes of Strobe / Location /
SOS, simply press the mode switch for more than one second again.
To exit special modes, simply press the on/off switch .
Strobe ready
With the light off, press the mode switch twice in quick succession to
enter strobe mode instantly. To exit, simply press any button and the light
will turn off.
Lockout/Unlock
With the light turned on, press and hold dual switches for more than one
second until the flashlight is switched off and enters into lockout mode. In
this mode, the EA41 can continue working on one set of batteries for over
12 months.
Lockout mode prevents accidental activation of the flashlight. To exit
lockout mode, simply press and hold dual switches for more than one
second again.
NOTE:
When the EA41 is kept in a backpack or left unused for extended periods,
Nitecore recommends removing the batteries to cut off power, thus
preventing battery drain or accidental activation of the flashlight.
