Battery Packs
Important Safety Instructions for All BatteryPacks
When ordering replacement battery packs, be sure to include
catalogue number andvoltage.
has reached an appropriate temperature, the yellow light will
turn off and the charger will resume the chargingprocedure.
The compatible charger(s) will not charge a faulty battery pack.
The charger will indicate faulty battery 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 authorised servicecentre.
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.
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
XR 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 in 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 25.4mm long
with a screw head diameter of 7–9mm, screwed into wood to
an optimal depth leaving approximately 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. Never let any liquid get inside the tool;
never immerse any part of the tool into aliquid.
•Do not use an extension cord unless it is absolutely
necessary. Use of improper extension cord could result in risk
of fire, electric shock, orelectrocution.
•Do not place any object on top of 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 charger with damaged cord or plug—
have them replacedimmediately.
•Do not operate charger if it has received a sharp blow,
been dropped, or otherwise damaged in any way. Take it
to an authorised servicecentre.
