The fuel gauge is an indication of approximate levels of charge remaining in the battery pack
according to the following indicators:
To actuate the fuel gauge, press and hold the fuel gauge button. A combination of the three
green LED lights will illuminate designating the level of charge left. When the level of charge in
the battery is below the usable limit, the fuel gauge will not illuminate and the battery will need
to be recharged.

nOTE: The fuel gauge is only an indication of the charge left on the battery pack. It does not
indicate tool functionality and is subject to variation based on product components, temperature
and end-user application.

The RBRC® Seal
The RBRC® (Rechargeable Battery Recycling Corporation) Seal on the nickel
cadmium, nickel metal hydride or lithium-ion batteries (or battery packs)
indicates that the costs to recycle these batteries (or battery packs) at the
end of their useful life have already been paid by D
is illegal to place spent nickel cadmium, nickel metal hydride or lithium-ion
batteries in the trash or municipal solid waste stream and the Call 2 Recycle® program provides
an environmentally conscious alternative.
Call 2 Recycle, Inc., in cooperation with D WALT and other battery users, has established the
e
program in the United States and Canada to facilitate the collection of spent nickel cadmium,
nickel metal hydride or lithium-ion batteries. Help protect our environment and conserve natural
resources by returning the spent nickel cadmium, nickel metal hydride or lithium-ion batteries to
an authorized D WALT service center or to your local retailer for recycling. You may also contact
e
your local recycling center for information on where to drop off the spent battery. RBRC® is a

Important Safety Instructions for All Battery Chargers

WARNING: Read all safety warnings and all instructions for the battery pack,
charger and power tool. Failure to follow the warnings and instructions may result
in electric shock, fire and/or serious injury.
• DO NOT attempt to charge the battery pack with any chargers other than the ones in
this manual. The charger and battery pack are specifically designed to work together.
• These chargers are not intended for any uses other than charging D
rechargeable batteries. Any other uses may result in risk of fire, electric shock or electrocution.
• Do not expose the charger to rain or snow.
• Pull by the plug rather than the cord when disconnecting the charger. This will reduce the
risk of damage to the electric plug and cord.
• Make sure that the cord is located so that it will not be stepped on, tripped over or
otherwise subjected to damage or stress.
• 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.
• When operating a charger outdoors, always provide a dry location and use an
extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the
risk of electric shock.
An extension cord must have adequate wire size (AWG or American Wire Gauge) for
•
safety. The smaller the gauge number of the wire, the greater the capacity of the cable, that is,
16 gauge has more capacity than 18 gauge. An undersized cord will cause a drop in line voltage
resulting in loss of power and overheating. When using more than one extension to make up
the total length, be sure each individual extension contains at least the minimum wire size. The
following table shows the correct size to use depending on cord length and nameplate ampere
rating. If in doubt, use the next heavier gauge. The lower the gauge number, the heavier the cord.

• 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.
•
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
battery packs. Other types of batteries may overheat and burst resulting in personal injury
and property damage.
NOTICE: Under certain conditions, with the charger plugged into the power supply, the
charger can be shorted by foreign material. 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 the 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.
Charging a Battery (Fig. D)
1. Plug the charger into an appropriate outlet before inserting battery pack.
FIG. D
2. Insert the battery pack into the charger, making sure the battery pack is fully seated in the
charger. The red (charging) light 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 on the battery pack and
then slide the battery pack out of the charger.
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.

* DCB107, DCB112, DCB113, DCB115, DCB118, DCB132: 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 compatible charger(s) 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.
