User Manual
Operation instructions
Battery installation
Unscrew the tailcap, insert 4 × 18650 Li-ion or 8 × CR123 batteries with
the positive (+) end pointing toward the flashlight head. Replace the
tailcap. In special circumstances, such as emergency situations, between
one and three 18650 Li-ion or two and six CR123 batteries may be used.
Note 1: Due to the strain using less than 4 x 18650 or 8 CR123 places
on batteries, Nitecore recommends using this feature only when
necessary and for short periods of time. Please see point
number 1 in the warning below.
Note 2: After loading batteries, “NITECORE” will be displayed on the
OLED screen for 2.5 seconds followed by battery voltage
(accurate to 0.01V) after which the TM26 will enter into standby
mode.
WARNING
1. Using less than 4 x 18650 or 8 x CR123 batteries can lead to turbo
mode malfunctioning, can trigger the overload protection circuit in
Li-ion batteries and can even lead to explosion of CR123 batteries. As
such Nitecore recommends this function is used with caution and only
when necessary.
2. Insert batteries with the positive (+) end pointing toward the flashlight
head.
3. Do not mix rechargeable and non-rechargeable batteries.
4. Do not mix batteries of different types/brands.
5. Do not mix batteries of different charge levels.
6. Do not use lithium batteries without a protected circuit board.
7. This product does not support unprotected 18650 Li-ion batteries.
Please also ensure that all the 18650 batteries used in the TM26 have
a button top configuration or they will not make contact with terminals
in the battery compartment. We recommend Nitecore 18650 batteries
for the best performance and reliability.
Charging the TM26
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 four
depleted 18650 batteries takes approximately 7 hours.
2. Under normal charging conditions, the on/off switch’s blue indicator
light will blink twice every second and the OLED screen with display
the word ‘Charging...” together with battery voltage.
3. If a problem is detected while charging the TM26 will stop charging, the
blue indicator will blink rapidly and the OLED display will show the
word “ERROR”. This is usually caused by faulty or incorrectly inserted
batteries.
4. When charging is
complete, the blue
indicator will remain on,
and “CHG.FINISHED”
along with battery voltage
will be displayed on the
OLED screen.
