Fast Charger
When the Knucklehead is placed into the charger the red
LED lights and the battery is fast-charging. When the bat-
tery is fully charged (appx.1 hour or less) the green LED
will light and the charger switches to a trickle (mainte-
nance) charge.
Optimal battery life can be achieved if the battery is fast
charged in moderate temperatures. Fast charging at low
temperature may cause the battery to lose some capacity.
The DC FAST CHARGER is equipped with a temperature
sensing system that automatically adjusts the current for
low temperature charging. This system works best when
the charger and the light are close to the same tempera-
ture. Avoid taking a Knucklehead from a cold environment
such as 40°F or lower and placing it into a warm charger.
Allow the Knucklehead to warm up for about a half hour
before placing it in the charger. If the light and charger are
colder than 40°F, the charge indicators will not light until
the system warms.
Steady Charger
The red LED indicates that the battery is being charged
at a steady rate. Charging will continue as long as power
is applied to the charger. The light may be continuously
charged in the steady charger at any temperature above
0°F.
WARNING: Use only genuine Streamlight

charger-
holders and cords. DO NOT remove the wall transformer
from an AC FAST CHARGER and connect it to a DC power
source; the charger will be destroyed.
MOUNTING THE CHARGER (VEHICLES)
The chargers are designed to be used in many positions.
Decide on a convenient location and make sure there is
enough clearance to insert and remove the flashlight.
Use the charger base as a template, mark the location
of the mounting holes and mount the charger securely
with appropriate hardware. Connect the charger to an ap-
propriate power source. The housing of all Knucklehead
chargers is electrically isolated and may be mounted to
the vehicle chassis.
