BATTERY REPLACEMENT
The flashlight is modular in design. Replacement of the lithium battery module is as
follows:
1. To remove the battery: Turn off the power; carefully rotate the battery counter clockwise away
from the ballast housing.
2. To replace the battery: Be careful to line up the battery with the ballast and rotate the battery
clockwise on to the ballast housing, be careful not to cross thread. Tighten snugly.
3.
DO NOT FORCE OR OVER TIGHTEN
as damage will occur and you will void your warranty.
NOTICE:
While replacing the battery, please make sure that your flashlight is in the “OFF” position;
otherwise damage can result to the lithium battery, electronic ballast and electrical connection between
ballast and lamp.
LAMP AND BALLAST REPLACEMENT
CAUTION NOTICE:
Before replacing lamp, make sure the light is “OFF” for a minimum of 10 minutes or
longer to ensure any stored power has dissipated, to avoid electric shock from stored energy in the
ballast, and temperature of lens has cooled enough to avoid being burned from high temperature.
The lens cap has a “fine thread”. Grasp the lamp-head-housing (serrated edge behind lens protector),
with one and while grasping the lens cap in the other, rotate the lens cap counter clockwise to access
the lamp.
While removing the lens cap, be careful not to drop lens, spacer and lamp to avoid damage.
While installing the lamp module, inspect the rubber O-rings for chaffing or breakage, Replace if signs of
wear. There is a plastic spacer between the lens and the outer reflector. The flat side faces the lens and
the slotted side faces the reflector. Check the rubber seal under the clear lens for wear or breakage,
replace if signs of wear. A dab of silicon lubricant or low mineral petroleum jelly should be used on the
threads of the light head before replacing the lens cap. Be careful not to cross thread and DO NOT
FORCE, or you will void your warranty and your light will be rendered inoperative.
BATTERY CHARGING NOTICE INFORMATION
A safety circuit is incorporated into the battery to protect from over-charging and rapid discharging of
the Lithium Ion battery. In the event of a rapid discharge, due to short circuiting the battery or an over
charge condition, the internal circuit will trip and render the battery inoperative and will have to be
replaced. The charger will indicate a full charge condition (Green LED), but the battery will not power
the light.
Do not short circuit the battery. A short circuit will occur if the electrical contacts, (contact rings), on the
inside end of the battery come in contact with each other by metal (such as coins, clips, pens, keys or
necklaces, etc.). This will cause the internal fuse to blow.
The battery and charger are calibrated to sense charge rate and charge capacity. Under normal
circumstances the system works reliably. Excessive temperature, power surges, or shock can cause the
circuits to sense an unstable condition that will cause the internal fuse to blow.
