DeWalt DC820 Instruction Manual page 6

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 U.S. 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.
SPECIFIC SAFETY INSTRUCTIONS FOR NICKEL CADMIUM
(NiCd) OR NICKEL METAL HYDRIDE (NiMH)
• 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:
a. and the battery liquid gets on your skin, immediately wash with
soap and water for several minutes.
b. and the 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.)
SPECIFIC SAFETY INSTRUCTIONS FOR LITHIUM ION (Li-lon)
• 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. Toxic fumes and materials are created when
lithium ion battery packs are burned.
• If battery contents come into contact with the skin,
immediately wash area with mild soap and water./f battery
liquid gets into the eye, rinse water over the open eye for 15
minutes or until irritation ceases. If medical attention is needed,
the battery electrolyte is composed of a mixture of liquid organic
carbonates and lithium salts.
• Contents of opened battery cells may cause respiratory
irritation. Provide fresh air. If symptoms persist, seek medical
attention.
_WARNING: Bum hazard. Battery liquid may be flammable if
exposed to spark or flame.

(Rechargeable Battery Recycling Corporation) Seal on
the nickel cadmium, nickel metal hydride or lithium ion
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 DEWALT. In
some areas, it is illegal to place spent nickel cadmium,
nickel metal hydride or lithium ion batteries in the trash
or municipal solid waste stream and the RBRC program provides an
environmentally conscious alternative.
RBRC
TM
in cooperation with DFWALT and other battery users, has
established programs in the United States and Canada to facilitate
the collection of spent nickel cadmium, nickel metal hydride or lithium
