Charger Operation; Important Charging Notes - DeWalt DCB104 Guide D'utilisation

OPERATION
The DCB104 battery charger (Fig. A) is designed to charge
D WALT 12V Max*, 20V Max* lithium-ion and FLEXVOLT ™
e
battery packs. This charger requires no adjustment and is
designed to be as easy as possible to operate. Simply place
your battery pack into a receptacle of a plugged in charger
and it will automatically charge the pack.
Charging a Battery (Fig. A)
1. Plug the charger into an appropriate outlet before
inserting battery pack.
2. Insert the battery pack(s)
sure each one is fully seated in the charger. The red
(charging) lights will blink continuously indicating that
the charging process has started.
3. The completion of charge will be indicated by the red
light remaining ON continuously. The battery pack is
fully charged and may be used at this time or left in the
charger. To remove the battery pack from the charger,
push the battery release button
nOTE: To ensure maximum performance and life of lithium-
ion battery packs, charge the battery pack fully before
first use.

Charger Operation

Refer to the indicators below for the charge status of the
battery pack.

Hot/Cold Pack Delay*
*The red light will continue to blink, but a yellow indicator
light will be illuminated during this operation. Once the
battery pack has reached an appropriate temperature, the
yellow light will turn off and the charger will resume the
charging procedure.
The charger will not charge a faulty battery pack. The
charger will indicate faulty battery pack by refusing to light.
nOTE: This could also mean a problem with a charger.
If the charger indicates a problem, take the charger and
battery pack to be tested at an authorized service center.
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 will charge at a slower rate than a warm
battery pack. The battery pack will charge at that slower rate
throughout the entire charging cycle and will not return to
maximum charge rate even if the battery pack warms.

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 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 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. The DCB104 battery charger is equipped with an
internal fan designed to cool the charger. The fan will
turn on automatically when the charger 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.
4. 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 tool, battery
pack and charger to your local service center.
5. 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.
6. 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.
7. Do not freeze or immerse the charger in water or any
other liquid.
