WARNING: If the plug or power cord is damaged,
it must be replaced by the manufacturer or its
representative or by an equally qualified person to
avoid danger.
Do not place any object on top of the charger or place
•
the charger on a soft surface that might block the
ventilation slots and result in excessive internal heat.
Place the charger in a position away from any heat source.
The charger is ventilated through slots in the top and the
bottom of the housing.
Do not operate the charger with a damaged cord
•
or plug–have them replaced immediately.
Do not operate the charger if it has received a sharp
•
blow, been dropped or otherwise damaged in any
way. Take it to an authorized service center.
Do not disassemble the charger; take it to an
•
authorized service center when service or repair
is required. Incorrect reassembly may result in a risk of
electric shock, electrocution or fire.
Disconnect the charger from the outlet before
•
attempting any cleaning. This will reduce the risk of
electric shock. Removing the battery pack will not reduce
this risk.
NEVER attempt to connect 2 chargers together.
•
The charger is designed to operate on standard
•
120V household electrical power. Do not attempt to
use it on any other voltage. This does not apply to the
vehicular charger.

WARNING: Shock hazard. Do not allow any liquid to
get inside the charger. Electric shock may result.

WARNING: Burn hazard. Do not submerge the battery
pack in any liquid or allow any liquid to enter the
battery pack. Never attempt to open the battery pack
for any reason. If the plastic housing of the battery pack
breaks or cracks, return to a service center for recycling.

CAUTION: Burn hazard. To reduce the risk of injury,
charge only D WALT rechargeable battery packs. Other
e
types of batteries may overheat and burst resulting in
personal injury and property damage.

CAUTION: Under certain conditions, with the charger
plugged into the power supply, the charger can be
shorted by foreign material. Foreign materials of a

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 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
14 foreign objects to enter the interior of the charger.

Electronic Protection System

12
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 if the Electronic Protection
System engages. If this occurs, place the lithium‑ion battery
pack on the charger until it is fully charged.

Important Charging Notes

1. Longest life and best performance can be obtained if
the battery pack is charged when the air temperature
is between 65 °F – 75 °F (18 ° C– 24 °C). DO NOT charge
when the battery pack is below +40 °F (+4.5 °C), or
above +104 °F (+40 °C). This is important and will
prevent serious damage to the battery pack.
2. 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.
3. 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. Move the charger and battery pack to a
location where the surrounding air temperature is
approximately 65 °F – 75 °F (18 °C – 24 °C);
d. If charging problems persist, take the tool, battery
pack and charger to your local service center.
4. The battery pack should be recharged when it fails
to produce sufficient power on jobs which were easily
done previously. DO NOT CONTINUE to use under these
conditions. Follow the charging procedure. You may also
charge a partially used pack whenever you desire with no
adverse effect on the battery pack.
5. Foreign materials of a conductive nature such as, but
not limited to, grinding dust, metal chips, steel wool,
aluminum foil, or any buildup of metallic particles should
be kept away from charger cavities. Always unplug the
charger from the power supply when there is no battery
pack in the cavity. Unplug the charger before attempting
to clean.
