supply when there is no battery pack in
the cavity.
Charging a Battery (Fig. A–C)
1. If the DEWALT 12V/20V MAX* Li-ion battery pack
is attached to the laser, remove it.
• While pressing down on the release button on the
battery pack (Figure
up to unlock it from the laser.
• Pull the battery pack the rest of the way up and
out of the laser (Figure
2. Plug the charger into an appropriate outlet.
3. Insert and fully seat battery pack (Fig.
The red charging light(s) will continuously blink
while charging.
4. Charging is complete when the red charging
light(s) remain(s) continuously ON. Battery pack
can be left in charger or removed (Fig.
Some chargers require the battery pack release
button to be pressed for removal (Fig.
WARNING: Only charge batteries in air
temperature over 40 ° F (4.5 ° C) and below
104 ° F (+40 ° C).
5. Charger will not charge a faulty battery pack,
which may be indicated by the charging light(s)
staying OFF. Take charger and battery pack to an
authorized service center if light(s) stay(s) OFF.
NOTE: Refer to label near charging light(s) on
charger for blink patterns. Older chargers may
have additional information and/or may not have a
yellow indicator light.
NOTE: To remove the battery pack, some
chargers require the battery pack release button
to be pressed.
6. Slide the battery pack down in the laser until it
snaps in place (Figure

• The bottom LED will illuminate and flash when the
battery level is low (10%). The laser may continue
to operate for a short time while the battery power
continues to drain, but the beam(s) will quickly dim.
• After the 12V/20V MAX Li-ion battery is charged, and
the laser is turned ON again, the laser beam(s) will
return to full brightness and the battery indicator level
will indicate full capacity.
• If all 4 LEDs on the battery meter remain ON, this
indicates that the laser is not fully powered OFF.
When the laser is not in use, make sure the Power/
Transport Lock switch is placed to the LEFT to the
Locked/OFF position (Figure
Hot/Cold Pack Delay
When the charger detects a battery pack that is too
hot or too cold, it automatically starts a Hot/Cold Pack
Delay, suspending charging until the battery pack has
reached an appropriate temperature. The charger then
automatically switches to the pack charging mode. This
feature ensures maximum battery pack life.
A cold battery pack may charge at a slower rate than a
warm battery pack.
The hot/cold pack delay will be indicated by the
red light(s) continuing to blink but with the yellow
light continuously ON. Once the battery pack has
reached an appropriate temperature, the yellow
light will turn OFF and the charger will resume the
charging procedure.
DCB118 and DCB1112 Chargers
The DCB118 and DCB1112 chargers are equipped with
an internal fan designed to cool the battery pack. The
fan will turn on automatically when the battery pack
needs to be cooled.
Never operate the charger if the fan does not operate
properly or if ventilation slots are blocked. Do not permit
foreign objects to enter the interior of the charger.
Electronic Protection System
Li-Ion tools are designed with an Electronic Protection
System that will protect the battery pack against
