Important Safety Instructions For All Battery Chargers - DeWalt DHS790 Guide D'utilisation

• 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. 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: Burn hazard. Battery liquid may be flammable if exposed to spark or flame.
WARNING: Fire hazard. Never 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: Fire hazard. Do not 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 Shipping.
e
Use Mode: When the FLEXVOLT™ battery stands alone or is in a D
product, it will operate as a 20V Max* 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. 2)
Some D WALT battery packs include a fuel gauge which consists of three green LED lights
e
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 (BB). 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.
For more information regarding fuel gauge battery packs, please contact call 1-800-4-D
(1-800-433-9258) or visit our website www.dewalt.com.
