LOCKOUT TAILCAP (US PAT. RE40125)
To enable, rotate tailcap clockwise until light activates when tailcap
pushbutton is pressed.
To lock out tailcap, rotate counterclockwise until light will not
activate when pushbutton is pressed.
LIGHT OPERATION
Press or click pushbutton tailcap switch once for High output.
Return to Off and press or click on again, within 2 seconds, for Low
output.
BATTERY REPLACEMENT
To load or replace batteries:
1. Unscrew bezel counterclockwise and remove.
2. Remove old batteries and dispose of properly.
3. Insert new 123A lithium battery(ies) or one SF18350/SF18650B
battery with the positive (+) terminal(s) oriented forward.
4. Replace bezel by screwing on clockwise. Press pushbutton
(with tailcap enabled) to test.
BATTERY INFORMATION & WARNINGS
For complete battery information and warnings, reference the enclosed
BATTERY INFORMATION / WARNING insert in your illumination tool’s
original packaging or visit www.surefire.com/batteries.
SAFETY
The internal protection circuit integrated within the battery assembly
provides the following safety features; overcharge, overdischarge,
short circuit, undervoltage, overvoltage.

Discharging: -20°C-+60°C, 65%±25%RH
Note: The battery’s metal button top also functions as a heatsink dur-
ing USB charging, which may result in it being very warm to the touch
during the high charge rate period.

SPECIFICATIONS
The SF18350/SF18650B are Lithium Ion protected batteries with micro
USB charge capability which allows the user to charge the batteries using
USB power sources such as a USB wall charger, computer, power bank, or
automotive USB port. An external 18350/18650 compatible CC-CV cradle
charger can be used to charge either battery; possibly at a faster rate if
so equipped.
The SF18350/SF18650B can be charged directly through the MICRO-
USB port, requiring no external charge cradle. The SF18350/SF18650B
comes with a 6-inch USB type A plug to Micro USB type B plug, with the
MICRO-USB plug being the end inserted into the battery. The battery side
includes a MICRO-USB type B receptacle. Once the cable is plugged into
the battery and a power source, the two LED indicators display the current
charge state: RED for charging and GREEN for fully charged. The battery
can be left connected to the charge source indefinitely as the internal
charge algorithm will restart the charge cycle once the cell voltage drops
below 4-5% of the float voltage. The charge time using the MICRO-USB
port for a fully depleted battery can be >5 hours. An external charger can
be used to shorten the total charge time. The batteries’ protection circuit
quiescent drain is 40uA, which in addition to the cell self-discharge, which
allows a fully charged battery to maintain usable capacity for 2-3 years.
