Important Safety Instructions for All 
Battery Packs
 
WARNING: Read all safety warnings and all 
instructions for the battery pack, charger and 
power tool. Failure to follow the warnings and 
instructions may result in electric shock, fire and/
or seriousinjury.
•  Do not charge or use the battery pack in explosive 
atmospheres, such as in the presence of flammable 
liquids, gases or dust. Inserting or removing the battery 
pack from the charger may ignite the dust orfumes.
•  NEVER force the battery pack into the charger. DO 
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 andchargers.
•  Charge the battery packs only in designated 
DeWALT
chargers.
•  DO NOT splash or immerse in water or otherliquids.
•  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, drylocation. 
NOTE: Do not store the battery packs in a tool with 
the trigger switch locked on. Never tape the trigger 
switch in the ONposition.
•  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 
areburned.
•  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 lithiumsalts.
•  Contents of opened battery cells may cause 
respiratory irritation. Provide fresh air. If symptoms 
persist, seek medicalattention.
 
WARNING: Burn hazard. Battery liquid may be 
flammable if exposed to spark orflame.
 
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 forrecycling.
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 shortcircuit.
Shipping the 
DeWALT
 FLEXVOLT™ Battery
The D
e
WALT FLEXVOLT™ battery has two modes: Use and 
Shipping. 
Use Mode: When the FLEXVOLT™ battery stands alone or is 
in a D
e
WALT 20V Max* 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 hourbatteries.
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”.
USE: 120 Wh Shipping: 3 x 40 Wh
Example of Use and Shipping Label Marking
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 
DeWALT
 battery packs include a fuel gauge which 
consists of three green LED lights that indicate the level of 
charge remaining in the batterypack.
The fuel gauge is an indication of approximate levels of 
charge remaining in the battery pack according to the 
followingindicators:
