Operation instructions

Battery installation (see adjacent diagram)

1. Unscrew the tail cap in a counter-clockwise

direction.

2. Insert one 18650 battery or two CR123

batteries with the positive pole pointing
forward (toward the light head).

NOTE:

Ensure batteries are inserted with the
positive (+) end pointing to the head. The
MH25 will not operate with incorrectly
inserted batteries.

Charging Function

The MH25 is capable of charging a protected 18650 Li-ion battery via the included
USB cable. Simply install a protected 18650 Li-ion cell, plugging one end of the USB
cable into the flashlight and the other end into a universal USB port / adaptor and the
MH25 will take care of the rest.

User Manual

Charging indicator light

1. Connect the charging cable to the flashlight and the A/C power adapter to the wall
outlet as shown in the adjacent image. Fully charging a depleted 18650 battery
takes approximately 6 hours.

2. Under normal charging conditions, the red indicator light near the charging port will
blink twice every second.

3. If a problem is detected during the charging process, the MH25 will stop charging
and the red indicator will blink rapidly. This is usually caused by faulty or
incorrectly inserted batteries.

4. When charging is complete, the red indicator will illuminate steadily.

Caution:

The MH25 needs to be turned on in
order to enter charging mode.

Switching ON/OFF

To switch ON: Press the button on the tailcap until a “click” is heard.
To switch OFF: Press the button on the tailcap a second time until a “click” is heard.

Mode Switching

The Nitecore MH25 has two modes: Turbo and user-defined. These two modes can
be changed by simply tightening and loosening the flashlight head. Turbo provides
100% output while user-defined contains five selectable sub-modes.

Turbo Mode

Turbo mode provides an output of 860 lumens and is accessed when the flashlight is

switched ON with the head lightly tightened. While in this mode, momentary

illumination can be achieved by switching off the flashlight and then half pressing and

holding the switch.

Note: After three minutes of use in turbo mode, the flashlight will lower its

output automatically to preventing overheating and increase runtime.

User-Defined Mode

User-defined mode is accessed by slightly loosening the flashlight head. In this mode,
lightly and rapidly pressing the switch will cycle through brightness and other
functions in the following order: “High-Mid-Low-SOS-Strobe”. Pressing the switch all
the way down will save and memorize a desired setting.

Tips: Make NITECORE MH25 your perfect Multitask Hybrid flashlight.

NITECORE MH25 flashlights essentially have two modes: Turbo mode (100% output)
and custom mode. Turbo mode is accessed by tightening the flashlight head while
any of the five customizable modes (strobe, SOS, low, medium and high) are selected
by loosening the head and rapidly pressing the on/off switch to cycle through the
modes. A given mode can be saved by simply turn off the light while in that mode.
Real-world examples include: When used as a flashlight around the home, the head
can be loosened and low level selected in custom mode, providing long runtimes at a
lower light intensity. The same flashlight could then be taken out and used a
law-enforcement duty light, with user-defined mode set in strobe, making it easy to
alternate between turbo mode and strobe with a simple twist of the flashlight head.

Maintenance

Every 6 months, threads should be wiped with a clean cloth followed by a thin coating
of silicon-based lubricant.
