Important Safety Instructions for All Battery Chargers
SAVE THESE INSTRUCTIONS: This manual contains important safety and operating 
instructions for battery chargers.
 • Before using the charger, read all instructions and cautionary markings on the 
charger, battery pack and product using the battery pack.
WARNING: Shock hazard. Do not allow any liquid to get inside the charger. Electric 
shock may result.
CAUTION: Burn hazard. To reduce the risk of injury, charge only DEWALT 
rechargeable battery packs. Other types of batteries may overheat and burst resulting 
in personal injury and property damage.
NOTICE: Under certain conditions, with the charger plugged into the power supply, the 
charger can be shorted by foreign material. Foreign materials of a conductive nature, 
such as, but not limited to, grinding dust, metal chips, steel wool, aluminum foil or any 
buildup of metallic particles should be kept away from the charger cavities. Always 
unplug the charger from the power supply when there is no battery pack in the cavity. 
Unplug the charger before attempting to clean.
 •DO NOT attempt to charge the battery pack with any chargers other than the 
ones in this manual. The charger and battery pack are specifically designed to 
work together. 
 • These chargers are not intended for any uses other than charging DEWALT 
rechargeable batteries. Any other uses may result in risk of fire, electric shock 
or electrocution.
 • Do not expose the charger to rain or snow.
 • Pull by the plug rather than the cord when disconnecting the charger. This will 
reduce the risk of damage to the electric plug and cord.
 • Make sure that the cord is located so that it will not be stepped on, tripped 
over or otherwise subjected to damage or stress.
 • Do not use an extension cord unless it is absolutely necessary. Use 
of improper extension cord could result in risk of fire, electric shock or 
electrocution.
 • When operating a charger outdoors, always provide a dry location and use an 
extension cord suitable for outdoor use. Use of a cord suitable for outdoor use 
reduces the risk of electric shock. 
 NOTE: Do not store the battery packs in a tool with the trigger switch locked 
on. Never tape the trigger switch in the ON position.
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.
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 (e.g., packed in suitcases and carry-on luggage) 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.
SPECIFIC SAFETY INSTRUCTIONS FOR LITHIUM ION (Li-Ion)
 • 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.
