Battery Options
Note:
EC2 is compatible with two primary CR123 Lithium batteries and one
18650 rechargeable Li-ion battery. When installing battery, EC2’s built-in
MCU will automatically detect the installed battery type, and then
automatically select the best suited driving data and battery capacity
detecting data.
WARNING
Always ensure batteries are inserted with the positive (+) ends pointing
toward the flashlight head. If incorrectly installed, the flashlight will not
work.
Switching ON/OFF
To switch ON: Press the “On/OFF” button once to turn the light on.
To switch OFF: Press the “On/OFF” button once again to turn the light
off.
Note: When EC2 is off, the power indicator (red light) will flash once
every 3 seconds to act as a locator. In this mode, the EC2 consumes a
very little amount of current (about 0.2mA) to maintain working of the
built-in MCU and power indicator. Under such status, two CR123
batteries will last about 1 year in this mode.
Brightness Selection
With the flashlight switched on, each time you press the “MODE” button,
it will go through the different preset brightness levels as follows:
ultra-low mode→low mode→medium mode→high mode then repeat.
Under this mode, the flashlight has a memory function. It can memorize
the selected brightness after turning the light off, while next time turning
on the light, it automatically resumes to the previously selected mode.
Entering Turbo Mode
With the flashlight switched on, press the “MODE” button for more than 1
Second, EC2 will enter Turbo mode. Press the MODE button again, the
flashlight will retreat from turbo brightness and resume to previous
brightness. In Turbo mode EC2 circuit will deliver maximum current to
make brightness as high as possible.
Thanks for purchasing NITECORE!
Operation instructions
Battery installation
1. Unscrew (counterclockwise) and remove the tail cap.
2. Insert two CR123 batteries or one 18650 battery with the positive
poles of the batteries pointing toward the head.
3. Replace the tail cap and fasten tightly
SIZE Nominal voltage Compatible
Primary Lithium battery CR123 3V Y (Recommended)
18650 Rechargeable Li-ion battery 18650 3.7V Y (Recommended)
Rechargeable Li-ion battery RCR123 3.7V Y
Note:
When EC2 is driven by 2 RCR123 batteries, the battery capacity indicator function
cannot be activated normally.
Brightness & Runtime
Note:
1. After 30 minutes working in Turbo mode, the flashlight will
automatically restore to the previously selected brightness level to
safeguard against overheating.
2. While activating Turbo mode, the brightness level increases about 150
lumens. Due to adaptability of human eyes, this brightness increase
may not be apparent within close range observation. In real-world
usage, Turbo mode can help EC2 throw to a longer range.
Entering Strobe and SOS Mode
With the light switched off, press the “ON/OFF” button for more than 1
second to enter Strobe mode. In strobe mode, press any button (ON/OFF
or MODE) to exit strobe and switch the light off.
With the light switched off, press the “MODE” button for more than 1
second to enter SOS mode. In SOS mode, press any button (ON/OFF or
MODE) to switch off the light and quit SOS mode.
Red Light Mode
With the light switched off, press the “MODE” button to enter red light
mode. In this mode, the power indicator will continuously emit red light
(0.2 lumens). Press the “MODE” button once again to quit the red light
mode.
Lockout Mode
With the light switched on, press the ON/OFF button for over 1 second to
enter lockout mode. In lockout mode, EC2 power source system will shut
down most of the circuit components to reduce its power consumption.
The MCU only consumes small amount of power to maintain its work. The
red light indicator also switches off to save energy. Under this mode, the
maximum consuming current is about 0.1mA, which ensures two CR123
batteries can maintain its work for around 2 years. In lockout mode, the 2
buttons on EC2 will not work, which can prevent the light from being
turned on accidentally.
To exit lockout mode, simply press the ON/OFF button for more than 1
second.
Note: When entering lockout mode, the red light indicator light will
continuously flash to advise of battery voltage. Please refer to the
“Power Indication” section below.
EC2
Power Indication
With the light switched on, and when the battery power has been
consumed by about 50%, the power indicator light (on the control panel)
will flash once every 6 seconds as a reminder of battery capacity.
When the battery power is almost depleted, the power indicator light will
flash 3 times every 3 seconds to indicate low battery capacity.
When entering lockout mode, the power indicator will automatically
detect and notify you of battery voltage (accurate to ±0.1V) with a series
of flashes. For example, if the battery voltage is 4.2V, the indicator will
flash 4 times, followed by a one second pause and then another 2
flashes.
Battery replacement
If battery level is low, the red power indicator light will flash three times
every 3 seconds. If the power level is critically low, the light will become
very dim and unresponsive to brightness adjustment. A replacement
battery is required at this time.
Maintenance
Every 6 months, the threads should be wiped with a clean cloth followed
by a thin coating of silicon-based lubricant.
