Charging a Battery (Fig. 1)
  1. Plug the charger into an appropriate outlet 
before inserting battery pack.
  2. Insert the battery pack (O) into the charger, 
making sure the battery pack is fully seated in 
the charger. The red (charging) light will blink 
repeatedly indicating that the charging process 
has started.
  3. The completion of charge will be indicated by 
the red light remaining ON continuously. The 
battery pack is fully charged and may be used 
at this time or left in the charger. To remove the 
battery pack from the charger, push the battery 
release button (P) on the battery pack.
NOTE: To ensure maximum performance and life of 
lithium-ion battery packs, charge the battery pack 
fully before first use.
Charger Operation
Refer to the indicators below for the charge status 
of the battery pack. 
Charge Indicators: DCB118
Charging
Fully Charged
Hot/Cold Pack Delay*
* DCB118:  The red light will continue to blink, but 
a yellow indicator light will be illuminated during 
this operation. Once the battery pack has reached 
an appropriate temperature, the yellow light will 
turn off and the charger will resume the charging 
procedure.
The compatible charger(s) will not charge a faulty 
battery pack. The charger will indicate faulty battery 
by refusing to light or by displaying problem pack or 
charger blink pattern.
NOTE: This could also mean a problem with a 
charger.
If the charger indicates a problem, take the charger 
and battery pack to be tested at an authorised 
service centre.
HOT/COLD PACK DELAY
When the charger detects a battery pack that is too 
hot or too cold, it automatically starts a Hot/Cold 
Pack Delay, suspending charging until the battery 
pack has reached an appropriate temperature. The 
charger then automatically switches to the pack 
charging mode. This feature ensures maximum 
battery pack life.
A cold battery pack will charge at a slower rate than 
a warm battery pack. The battery pack will charge 
  •  Do not expose charger to rain or snow.
  •  Pull by plug rather than cord when 
disconnecting charger. This will reduce risk 
ofdamage to electric plug and cord.
  •  Make sure that 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.
  •  Do not place any object on top of charger 
or place the charger on a soft surface that 
might block the ventilation slots and result 
in excessive internal heat. Place the charger 
in a position away from any heat source. The 
charger is ventilated through slots in the top and 
the bottom of the housing.
  •  Do not operate charger with damaged cord 
or plug—have them replaced immediately.
 • Do not operate charger if it has received 
a sharp blow, been dropped, or otherwise 
damaged in any way. Take it to an authorised 
service centre.
  •  Do not disassemble charger; take it to an 
authorised service centre when service or 
repair is required. Incorrect reassembly may 
result in a risk of electric shock, electrocution or 
fire.
  •  In case of damaged power supply cord the 
supply cord must be replaced immediately by 
the manufacturer, its service agent or similar 
qualified person to prevent any hazard.
  •  Disconnect the charger from the outlet 
before attempting any cleaning. This will 
reduce the risk of electric shock. Removing 
the battery pack will not reduce this risk.
  • NEVER attempt to connect two chargers 
together.
  •  The charger is designed to operate on 
standard 220-240 household electrical 
power. Do not attempt to use it on any 
other voltage. This does not apply to the 
vehicular charger.
