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:
liquid may be flammable if exposed to spark or flame.
WARNING:
attempt 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 with a hammer, stepped on). Damaged
battery packs should be returned to the service center
for recycling.
Transportation
WARNING:
store or carry the battery pack so that metal objects
can contact exposed battery terminals. For 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.
shipping the D WALT FlEXVOlT™ Battery
e
The D WALT FLEXVOLT™ battery has two modes: Use and
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
Shipping Watt hour rating indicates 3 x 40 Wh, meaning 3
batteries of 40 Watt hours each. The Use Watt hour rating
indicates 120 Watt hour (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.
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.
Fig. B
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 WALT. In some areas, it is illegal to place
e
spent nickel cadmium, nickel metal hydride or lithium-ion
batteries in the trash or municipal solid waste stream and
