Charger Operation; Important Charging Notes - DeWalt DCB107 Guide D'utilisation

The battery pack is fully charged and may be used at this time or
left in the charger.
To ensure maximum performance and life of lithium­ion battery
NOTE:
packs, charge the battery pack fully before first use.

Charger Operation

Refer to the indicators below for the charge status of the battery pack.
Charge Indicators
Charging
Fully Charged
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.
This could also mean a problem with a charger.
NOTE:
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.
LITHIUM-ION BATTERY PACKS ONLY
Li­Ion 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 lithium­ion 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. If the battery pack does not charge properly:
a. Check operation of the receptacle by plugging in a lamp or
other appliance;
b. Check to see if the receptacle is connected to a light switch
which turns the 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.
