NOTE: To ensure maximum performance and life of 
Li-Ion batteries, charge the battery pack fully before 
first use.
Charging Process
Refer to the table below for the state of charge of 
the battery pack.

Hot/Cold Pack Delay
When the charger detects a battery that is too hot 
or too cold, it automatically starts a Hot/Cold Pack 
Delay, suspending charging until the battery has 
reached an appropriate temperature. The charger 
then automatically switches to the pack charging 
mode. This feature ensures maximum battery life.
LI-ION BATTERY PACKS ONLY 
Li-Ion batteries are designed with an Electronic 
Protection System that will protect the battery 
against overloading, overheating or deep discharge. 
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.
Important Safety Instructions for All 
Battery Packs
When ordering replacement battery packs, be sure 
to include 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. Then follow 
charging procedures outlined.
READ ALL INSTRUCTIONS
  •  Do not charge or use battery in explosive 
atmospheres, such as in the presence of 
flammable liquids, gases or dust. Inserting 
or removing the battery from the charger may 
ignite the dust or fumes.
  •  Never force battery pack into charger. Do 
not modify 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 D
EWALT 
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).
 WARNING: Never attempt to open the 
battery pack for any reason. If battery 
pack case is cracked or damaged, 
do not insert into 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 (i.e., pierced with a nail, hit with a 
hammer, stepped on). Electric shock 
or electrocution may result. Damaged 
battery packs should be returned to 
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 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.
