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.
•  DO NOT attempt to charge the battery pack with 
any chargers other than a DeWALT  charger. DeWALT  
chargers and battery packs are specifically designed to 
worktogether.
•  These chargers are not intended for any uses other 
than charging DeWALT  rechargeable battery packs. 
Charging other types of battery packs may cause them to 
overheat and burst, resulting in personal injury, property 
damage, fire, electric shock orelectrocution.
•  Do not expose the charger to rain orsnow.
•  Do not allow water or any liquid to entercharger.
•  Pull by the plug rather than the cord when 
disconnecting the charger. This will reduce the risk of 
damage to the electric plug andcord.
•  Make sure that the cord is located so that it will not 
be stepped on, tripped over or otherwise subjected to 
damage orstress.
•  Do not use an extension cord unless it is absolutely 
necessary. Use of improper extension cord could result in 
risk of fire, electric shock orelectrocution.
•  When operating a charger outdoors, always provide 
a dry location and use an extension cord suitable

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.
Shipping the DeWALT FLEXVOLT™ Battery Pack
The DeWALT FLEXVOLT™ battery pack has a battery cap that 
should be used when shipping the batterypack.
•  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.
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.
