The tool will automatically turn off if the Electronic 
Protection System engages. If this occurs, place the 
Li-Ion battery on the charger until it is fully charged.
A cold battery pack will charge at about half the rate 
of a warm battery pack. The battery pack will charge 
at that slower rate throughout the entire charging 
cycle and will not return to maximum charge rate 
even if the battery warms.
Important Safety Instructions for All 
Battery Packs
When ordering replacement battery packs, be sure 
to include the catalog number and voltage. 
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 
the 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 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.  
  •  Charge the battery packs only in designated 
DEWALT 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 results, make sure the battery pack is 
fully charged before use.
   WARNING: Never attempt to open 
the battery pack for any reason. If 
the battery pack case is cracked or 
damaged, do not insert it into the 
charger. Do not crush, drop or damage 
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). Electric shock or electrocution may 
result. Damaged battery packs should 
be returned to the service centre for 
recycling.
 
 CAUTION: When not in use, place 
tool on its side on a stable surface 
where it will not cause a tripping or 
falling hazard. Some tools with large 
battery packs will stand upright on the 
battery pack but may be easily knocked 
over.
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 the area with 
mild soap and water. If the 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 persists, seek medical attention.
 
 WARNING: Burn hazard. Battery liquid 
may be flammable if exposed to spark 
or flame.
 Transportation 
DEWALT batteries comply with all applicable 
shipping regulations as prescribed by industry and 
legal standards which include UN Recommendations 
on the Transport of Dangerous Goods; International 
Air Transport Association (IATA) Dangerous Goods 
Regulations, International Maritime Dangerous 
Goods (IMDG) Regulations, and the European 
Agreement Concerning The International Carriage 
of Dangerous Goods by Road (ADR). Lithium-ion 
cells and batteries have been tested to section 38.3 
of the UN Recommendations on the Transport of 
Dangerous Goods Manual of Tests and Criteria.
In most instances, shipping a DEWALT battery pack 
will be excepted from being classified as a fully 
regulated Class 9 Hazardous material. In general, the 
two instances that require shipping Class 9 are:
  1. Air shipping more than two D
EWALT lithium-ion 
battery packs when the package contains only 
battery packs (no tools), and
  2. Any shipment containing a lithium-ion battery 
with an energy rating greater than 100 watt 
hours (Wh). All lithium-ion batteries have the 
watt hour rating marked on the pack.
