Chargers
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 chart on back cover for compatibility of chargers and bat-
tery packs.
Using Tune-Up™ Mode
The Tune-up™ mode will equalize or balance the individual cells in
the battery pack at its peak capacity. This cycle takes up to 8 hours
to complete. Battery packs should be tuned up weekly or after 10
to 20 charge/discharge cycles or whenever the pack no longer
delivers the same amount of work.
1. To tune up your battery pack, place the battery in the charger as
usual. The red light will blink continuously indicating that the
charge cycle has started.
2. The Tune-up™ Button may be pressed at any time after the
charge has started. The red light will stop blinking momentarily,
blink quickly 3 times, and then resume blinking continuously.
The charger is now giving your batteries a tune-up.
3. When the charge cycle has completed, the light will stay on con-
tinuously. The pack is fully charged and may be used at this time
or left in the charger.
4. If you select Tune-up™ and then change your mind, remove the
battery from the charger. After 5 seconds, insert the battery into
the charger. The normal charge cycle will commence.
Charging Procedure
1 HOUR CHARGERS
1. Plug the charger into an appropriate power outlet.
2. Insert the battery pack into the charger, as shown in FIG.1,
making sure the pack is fully seated in the charger. The red
(charging) light will blink continuously indicating that the charg-
ing process has started.
3. The battery pack will be fully charged in about 1 hour. The com-
pletion 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.
TROUBLE 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, re-insert battery pack into the
charger. If the problem persists, try a different battery pack to deter-
mine 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.
