Important Safety Instructions for All 
Battery Chargers
 
WARNING: Read all safety warnings, 
instructions, and cautionary markings for the 
battery pack, charger and product. Failure to 
follow the warnings and instructions may result 
in electric shock, fire and/or seriousinjury.
Shipping the DeWALT FLEXVOLT™ Battery Pack
The DeWALT FLEXVOLT™ battery pack has a battery cap that 
should be used when shipping the batterypack.
Attach the cap to the battery pack to ready it for shipping.   
This converts the battery pack to three separate 20V 
batteries. The three batteries have the Watt hour rating 
labeled “Shipping” on the battery pack. If shipping without 
the cap or in a tool, the pack is one battery at the Watt hour 
rating labeled“Use”.
Example battery pack label:
 
USE: 120Wh   SHIPPING: 3x 40Wh
In this example, the battery pack is three batteries with 
40Watt hours each when using the cap. Otherwise, the 
battery pack is one battery with 120Watthours.
Transportation
 
WARNING: Fire hazard. Do not store, 
carry, or transport 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, coins, hand tools, etc. 
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: Li‑ion battery packs should 
not be put in checked baggage on airplanes and must 
be properly protected from short circuits if they are in 
carry‑onbaggage.
•  DO NOT splash or immerse in water or otherliquids.
•  DO NOT allow water or any liquid to enter batterypack.
•  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.
•  Do not expose a battery pack or appliance to fire or 
excessive temperature. Exposure to fire or temperature 
above 265°F (130°C) may causeexplosion.
•  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 15minutes 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.
•  Battery liquid may be flammable if exposed to spark 
orflame.
•  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.
Storage Recommendations
The best storage place is one that is cool and dry, away 
from direct sunlight and excess heat or cold.  Store the fully 
charged battery pack out of thecharger.
Battery Pack Cleaning Instructions
Dirt and grease may be removed from the exterior of the 
battery pack using a cloth or soft non‑metallic brush. Do not 
use water or any cleaningsolutions.
Fuel Gauge Battery Packs (Fig.B)
Some battery packs include a fuel gauge. When the fuel 
gauge button is pressed and held, the LED lights will 
indicate the approximate level of charge remaining. This 
does not indicate tool functionality and is subject to 
variation based on product components, temperature, and 
end‑userapplication.
