stays OFF.
NoTE: Refer to label near charging light on charger
for blink patterns. Older chargers may have additional
information and/or may not have a yellow indicator light.
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
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.

Electronic Protection System

Li-Ion tools are designed with an Electronic Protection
System that will protect the battery pack against overloading,
overheating or deep discharge. The tool will automatically
turn off and the battery pack will need to be recharged.

Important Charging Notes

1. The charger and battery pack may become warm to the
touch while charging. This is a normal condition, and
does not indicate a problem. To facilitate the cooling of
the battery pack after use, avoid placing the charger or
battery pack in a warm environment such as in a metal
shed or an uninsulated trailer.
2. If the battery pack does not charge properly:
a. Check operation of receptacle by plugging in a lamp
or other appliance;
b. Check to see if receptacle is connected to a light
switch which turns power off when you turn out
the lights;
c. If charging problems persist, take the tool, battery
pack and charger to your local service center.
3. You may charge a partially used pack whenever you
desire with no adverse effect on the battery pack.
Charger Cleaning Instructions

WARNING: Shock hazard. Disconnect the charger
from the AC outlet before cleaning. Dirt and grease
may be removed from the exterior of the charger using

any cleaning solutions.

Wall Mounting

Some D WALT chargers are designed to be wall mountable
e
or to sit upright on a table or work surface. If wall mounting,
locate the charger within reach of an electrical outlet, and
away from a corner or other obstructions which may impede
air flow. Use the back of the charger as a template for the
location of the mounting screws on the wall. Mount the
charger securely using drywall screws (purchased separately)
at least 1" (25.4 mm) long, with a screw head diameter of
0.28–0.35" (7–9 mm), screwed into wood to an optimal
depth leaving approximately 7/32" (5.5 mm) of the screw
exposed. Align the slots on the back of the charger with the
exposed screws and fully engage them in the slots.
