NOTICE
The above data has been measured in accordance with the international
flashlight testing standards ANSI/NE MA FL 1 using 4 x 1.2V 2400mAh AA
batteries under laboratory conditions. The data may vary slightly during real-
world use due to battery type, individual usage habits and environmental
factors.
Operation Instructions
Battery installation
- Insert batteries with the positive(+) and negative(-) ends corresponding to the diagram on the inside of the battery compartment.
- Tighten the tail cap by aligning the two gold pins on the inside of the tail cap with the corresponding holes on the flashlight body and rotate clockwise.
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.
- Do not mix rechargeable and non-rechargeable batteries.
- Do not mix batteries of different types/brands.

location of the EA41. In this mode, the EA41 can keep running on 4 x AA
batteries for 120 days.
NOTE: With the power indicator off in standby mode, the EA41 can work for
more than 12 months with 4 x AA batteries.
Brightness Levels

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.

one second to create ultra-low output of 1 lumen; II] Instant turbo: with the
light off, press the mode switch for more than one second to create turbo
output of 1020 lumens.
NOTE: The EA41 will lower its output lumens after 20 minutes of use to
prevent overheating and preserve battery longevity.

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.
Power Tips
Each time batteries are inserted, or the mode switch is pressed with EA41 turned off, the blue LEDs will blink to indicate battery levels:
- Three times for battery levels over 50%;
- Twice for battery levels below 50%;
- Once for battery levels close to depletion (below 10%).
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.
