throughout the entire charging cycle and will not return to
maximum charge rate even if the battery pack warms.
The DCB118 charger is 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 appliances are designed with an Electronic
Protection System that will protect the battery pack against
overloading, overheating or deep discharge.
The appliance 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.
Wall Mounting
These chargers are designed to be wall mountable 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.
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
a cloth or soft non-metallic brush. Do not use water or
any cleaning solutions.
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 and 75 °F (18 ° – 24 °C). DO NOT charge
the battery pack in an air temperature 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 ° – 24 °C);
d. If charging problems persist, take the 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.
6. Do not freeze or immerse the charger in water or any
other liquid.
Storage Recommendations
1. The best storage place is one that is cool and dry, away
from direct sunlight and excess heat or cold.
2. For long storage, it is recommended to store a fully
charged battery pack in a cool dry place out of the
charger for optimal results.
nOTE:
Battery packs should not be stored completely
depleted of charge. The battery pack will need to be
recharged before use.
