Important Safety Instructions for Battery Packs
The DC021 and DC022 will charge 7.2 volt–18 Volt D E WALT battery packs and will provide light
using 12–18 Volt D E WALT battery packs. When ordering replacement battery packs, be sure to
include catalog number and voltage. Extended Run-Time battery packs deliver more run-time
than standard battery packs. Consult the chart in this manual for compatibility of chargers and bat-
tery packs.
The battery pack is not fully charged out of the carton. Before using the battery pack and
worklight/charger, read the safety instructions below. Then follow charging procedures outlined.
READ ALL INSTRUCTIONS
• Do not incinerate the battery pack even if it is severely damaged or is completely worn
out. The battery pack can explode in a fire.
• A small leakage of liquid from the battery pack cells may occur under extreme usage
or temperature conditions. This does not indicate a failure. However, if the outer seal is
broken and this leakage gets on your skin:
a. Wash quickly with soap and water.
b. Neutralize with a mild acid such as lemon juice or vinegar.
c. If battery liquid gets into your eyes, flush them with clean water for a minimum of
10 minutes and seek immediate medical attention. (Medical note: The liquid is 25-35%
solution of potassium hydroxide.)
• Charge the battery packs only in D E WALT chargers.
• DO NOT splash or immerse in water or other liquids.
• Do not store or use the tool and battery pack in locations where the temperature may
reach or exceed 105°F (such as outside sheds or metal buildings in summer).
DANGER: Electrocution hazard. Never attempt to open the battery pack for any reason. If
battery pack case is cracked or damaged, do not insert into charger. Electric shock or electro-
cution may result. Damaged battery packs should be returned to service center for recycling.
NOTE: Battery storage and carrying caps are provided for use whenever the battery
is out of the tool or charger. Remove cap before placing battery in charger or tool.
WARNING: Fire hazard. Do not store or carry battery so that metal objects
can contact exposed battery terminals. For example, do not place battery in
aprons, pockets, tool boxes, product kit boxes, drawers, etc., with loose nails,
screws, keys, etc. without battery cap. Transporting batteries can possibly cause
fires if the battery terminals inadvertently come in contact with conductive materials such
as keys, coins, hand tools and the like. The US Department of Transportation Hazardous
Material Regulations (HMR) actually prohibit transporting batteries in commerce or on airplanes
(i.e., packed in suitcases and carry-on luggage) UNLESS they are properly protected from short
circuits. So when transporting individual batteries, make sure that the battery terminals are
protected and well insulated from materials that could contact them and cause a short circuit.
The RBRC™ Seal
The RBRC™ (Rechargeable Battery Recycling Corporation) Seal on the
nickel cadmium and nickel metal hydride batteries (or battery packs) indicate that
the costs to recycle these batteries (or battery packs) at the end of their useful life
have already been paid by D
E WALT. In some areas, it is illegal to place spent
nickel cadmium and nickel metal hydride batteries in the trash or municipal solid
waste stream and the RBRC program provides an environmentally conscious alternative.
RBRC™ in cooperation with D
E WALT and other battery users, has established programs in the
United States and Canada to facilitate the collection of spent nickel cadmium and nickel metal
hydride batteries. Help protect our environment and conserve natural resources by returning
the spent nickel cadmium and nickel metal hydride batteries to an authorized D
E WALT service
center or to your local retailer for recycling. You may also contact your local recycling center for
information on where to drop off the spent battery.
RBRC™ is a registered trademark of the Rechargeable Battery Recycling Corporation.
Worklight/Charger
The DC021 and DC022 will charge 7.2–18 Volt D E WALT battery packs and will provide light
using 12–18 Volt D E WALT battery packs. Your battery may also be charged in D E WALT 1 hour
chargers, 15 minute chargers or vehicular 12 volt chargers. Be sure to read all safety
instructions before using your charger. Consult the chart in this manual for compatibility of
chargers and battery packs.
The 38W fluorescent worklight will run on 12–18V D
E WALT batteries or 120V AC Power. The
1-hour charger and the three power outlets will ONLY function when the worklight/charger is
plugged into AC power and CANNOT be powered by D
E WALT batteries.
Charging Procedure (Fig. 1, 4)
DANGER: Electrocution hazard. 120 volts present at charging terminals. Do not probe with
conductive objects. Danger of electric shock or electrocution.
WARNING: Pinch hazard. Do not release the battery hold-down quickly. Personal injury may
result.
1. Plug the worklight/charger power cord (E) into an appropriate AC power outlet or generator.
2. Lift the battery hold-down (G) with one hand and insert the battery pack into the charging
receptacle. Slowly place the battery hold-down on battery pack to hold battery pack firmly.
3. The red light on the top rear of the base will blink continuously indicating that the charging
process has started.
4. The completion of charge will be indicated by the red light remaining ON continuously.
5. Charge time for D
E WALT 7.2 –18 V battery packs is approximately one hour.
Indicator Light Operation
Charge Indicators
The worklight/charger is designed to detect certain problems that can arise with battery packs.
Problems are indicated by the red light flashing at a fast rate. If this occurs, re-insert battery pack
into the worklight/charger. If the problem persists, try a different battery pack to determine if the
worklight/charger is OK. If the new pack charges correctly, then the original pack is defective and
should be returned to a service center or other collection site for recycling. If the new battery
pack elicits the same trouble indication as the original, have the worklight/charger tested at an
authorized service center.
HOT/COLD PACK DELAY
The worklight/charger has a Hot/Cold Pack Delay feature: when the worklight/charger detects a
battery that is hot, it automatically starts a Hot Pack Delay, suspending charging until the battery
has cooled. After the battery has cooled, the worklight/charger automatically switches to the
Pack Charging mode. This feature ensures maximum battery life. The red light flashes long, then
short while in the Hot Pack Delay mode.
PROBLEM POWER LINE
The worklight/charger has a Problem Power Line indicator. When the worklight/charger is used
with some portable power sources such as generators or sources that convert DC to AC, the
worklight/charger may temporarily suspend operation, flashing the red light with two fast
blinks followed by a pause. This indicates the power source is out of limits.
LEAVING THE BATTERY PACK IN THE WORKLIGHT/CHARGER
The worklight/charger and battery pack can be left connected with the red light glowing indefi-
nitely. The worklight/charger will keep the battery pack fresh and fully charged.
NOTE: A battery pack will slowly lose its charge when kept out of the worklight/charger. If the
battery pack has not been kept on maintenance charge, it may need to be recharged before use.
A battery pack may also slowly lose its charge if left in a worklight/charger that is not plugged
into an appropriate AC source.
WEAK BATTERY PACKS: The worklight/charger can also detect a weak battery. Such
batteries are still usable but should not be expected to perform as much work. In such cases,
about 10 seconds after battery insertion, the worklight/charger will beep rapidly 8 times to
indicate a weak battery condition. The worklight/charger will then go on to charge the battery to
the highest capacity possible.
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 +105°F (+40.5°C). This is important and
will prevent serious damage to the battery pack.

2. The worklight/charger and battery pack may become warm to 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 worklight/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 current at 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 worklight/charger and battery pack to a location where the surrounding air tem-
perature is approximately 65°F - 75°F (18° - 24°C).
d. If charging problems persist, take the tool, battery pack and worklight/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 affect on the battery pack.
5. Under certain conditions, with the worklight/charger plugged into the power supply, the
exposed charging contacts inside the charger can be shorted by foreign material. Foreign
materials of a conductive nature such as, but not limited to, steel wool, aluminum foil, or any
buildup of metallic particles should be kept away from worklight/charger cavities. Always
keep the battery door closed when there is no battery pack in the cavity. Unplug
worklight/charger before attempting to clean.
6. Do not freeze or immerse the worklight/charger in water or any other liquid.
WARNING: Shock hazard. Don’t allow any liquid to get inside the worklight/charger. Electric
shock may result.
CAUTION: 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.
