NOT modify the battery pack in any way to fit into
a non-compatible charger as battery pack may
rupture causing serious personal injury. Consult
the chart at the end of this manual for compatibility of
batteries and chargers.
• Charge the battery packs only in designated
D WALT chargers.
e
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 104 °F (40 °C) (such as outside sheds or metal
buildings in summer). For best life store battery packs in
a cool, dry location.
NOTE: Do not store the battery packs in a tool with
the trigger switch locked on. Never tape the trigger
switch in the ON position.
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.
Do not expose battery pack or tool/appliance to
•
fire or excessive temperature. Exposure to fire or
temperature above 265°F (130°C) may cause explosion.
If battery contents come into contact with the skin,
•
immedicately wash area with mild soap and water.
If 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:
may be flammable if exposed to spark or flame.

WARNING:
to open the battery pack for any reason. If the battery
pack case is cracked or damaged, do not insert into
the charger. Do not crush, drop or damage the battery
pack. Do not use a battery pack or charger that has
received a sharp blow, been dropped, run over or
damaged in any way (e.g., pierced with a nail, hit

Fire hazard. Do not store
example, do not place the battery pack in aprons,
pockets, tool boxes, product kit boxes, drawers, etc.,
with loose nails, screws, keys, etc. 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 in carry-on baggage UNLESS they
are properly protected from short circuits. So when
transporting individual battery packs, make sure that
the battery terminals are protected and well insulated
from materials that could contact them and cause a
short circuit.
NOTE:
Lithium-ion batteries should not be put
in checked baggage.
shipping the D WALT FlEXVOlT™ Battery
e
WALT FLEXVOLT™ battery has two modes: Use and
The D
e
shipping.
Use Mode: When the FLEXVOLT™ battery stands alone or is
in a D WALT 20V Max* product, it will operate as a 20V Max*
e
battery. When the FLEXVOLT™ battery is in a 60V Max* or a
120V Max* (two 60V Max* batteries) product, it will operate
as a 60V Max* battery.
shipping Mode: When
the cap is attached to
the FLEXVOLT™ battery,
the battery is in Shipping
Mode. Strings of cells are
electrically disconnected within the pack resulting in three
batteries with a lower Watt hour (Wh) rating as compared
to one battery with a higher Watt hour rating. This increased
quantity of three batteries with the lower Watt hour rating
can exempt the pack from certain shipping regulations that
are imposed upon the higher Watt hour batteries.
The battery label indicates two Watt hour ratings (see
example). Depending on how the battery is shipped, the
appropriate Watt hour rating must be used to determine the
applicable shipping requirements. If utilizing the shipping
cap, the pack will be considered 3 batteries at the Watt hour
rating indicated for "Shipping". If shipping without the cap or
in a tool, the pack will be considered one battery at the Watt
hour rating indicated next to "Use".
Example of Use and Shipping Label Marking
USE: 120 Wh Shipping: 3 x 40 Wh
For example, Shipping Wh rating might indicate 3 x 40 Wh,
meaning 3 batteries of 40 Watt hours each. The Use Wh
rating might indicate 120 Wh (1 battery implied).
Fuel Gauge Battery Packs (Fig. B)
Some D WALT battery packs include a fuel gauge which
e
consists of three green LED lights that indicate the level of
charge remaining in the battery pack.
