Important Safety Instructions for All Battery Packs

When ordering replacement battery packs, be sure to include the catalog number and 

voltage. Consult the chart at the end of this manual for compatibility of chargers and 

battery packs.
The battery pack is not fully charged out of the carton. Before using the battery pack 

and charger, read the safety instructions below and then follow charging procedures 

outlined.

READ ALL INSTRUCTIONS

 • 

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 or fumes.

  •  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 and chargers.

  •  Charge the battery packs only in designated D

E

WALT chargers.

 • 

DO NOT

 splash or immerse in water or other liquids.

  •  Do not store or use the tool and battery pack in locations where the 

temperature may reach or exceed 40 °C (105 °F) (such as outside sheds 

or metal buildings in summer).

For best life store battery packs in a cool, dry 

location.

    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.
