Chargers
Your tool uses a D

WALT charger. Your battery can be charged in D
E
WALT 1 Hour
Chargers, 15 Minute Chargers or Vehicular 12 Volt Charger. Be sure to read all safety
instructions before using your charger. Consult the chart at the end of this manual for
compatibility of chargers and battery packs.
Charging Procedure (Fig. 1)
DANGER:
Electrocution Hazard. 230 volts are present at charging terminals. Do not
probe with conductive objects. Electric shock or electrocution may result.
1. Plug the charger into an appropriate outlet before inserting battery pack.
2. Insert the battery pack into the charger, as shown in Figure 1, making sure the pack
is fully seated. The red (charging) light will blink continuously indicating that the
charging process has started.
3. The completion of charge will be indicated by the red light remaining ON
continuously. The pack is fully charged and may be used at this time or left in the
charger.
Indicator Light Operation
Charge Indicators
Some chargers are designed to detect certain problems that can arise with battery packs.
Problems are indicated by the red light flashing at a fast rate. If this occurs, reinsert
battery pack into the charger. If the problem persists, try a different battery pack to
determine if the charger is OK. If the new pack charges correctly, then the original pack is
defective and should be returned to a service center or other collection site for recycling.
If the new battery pack elicits the same trouble indication as the original, have the charger
tested at an authorized service center.
HOT/COLD PACK DELAY
Some chargers have a Hot/Cold Pack Delay feature: when the charger detects a
battery that is hot, it automatically starts a Hot Pack Delay, suspending charging
until the battery has cooled. After the battery has cooled, the charger automatically
switches to the Pack Charging mode. This feature ensures maximum battery life. The
red light flashes long, then short while in the Hot Pack Delay mode.
PROBLEM POWER LINE
Some chargers have a Problem Power Line indicator. When the charger is used with some
portable power sources such as generators or sources that convert DC to AC, the charger
may temporarily suspend operation, flashing the red light with two fast blinks followed by a
pause. This indicates the power source is out of limits.
LEAVING THE BATTERY PACK IN THE CHARGER
The charger and battery pack can be left connected with the red light glowing
indefinitely. The charger will keep the battery pack fresh and fully charged.
NOTE:
A battery pack will slowly lose its charge when kept out of the charger. If the
battery pack has not been kept on maintenance charge, it may need to be recharged
before use. A battery pack may also slowly lose its charge if left in a charger that is
not plugged into an appropriate AC source.
WEAK BATTERY PACKS:
Chargers can also detect a weak battery. Such batteries
are still usable but should not be expected to perform as much work. In such cases,
about 10 seconds after battery insertion, the charger will beep rapidly 8 times to
indicate a weak battery condition. The charger will then go on to charge the battery
to the highest capacity possible.
Important Charging Notes
1. Longest life and best performance can be obtained if the battery pack is charged
when the air temperature is between 18°- 24°C (65°F and 75°F). DO NOT charge
the battery pack in an air temperature below +4.5°C (+40°F), or above +40.5°C
(+105°F). This is important and will prevent serious damage to the battery pack.
2. The charger and battery pack may become warm to touch while charging. This
is a normal condition, and does not indicate a problem. To facilitate the cooling
of the battery pack after use, avoid placing the charger or battery pack in a warm
environment such as in a metal shed, or an uninsulated trailer.
3. If the battery pack does not charge properly:
a. Check current at receptacle by plugging in a lamp or other appliance.
