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 charging process has
started.
3. The battery pack will be fully charged in about 1 hour. 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.
TROUBLE INDICATORS: These chargers are designed to detect
certain problems that can arise with battery packs which would be
indicated by the red light flashing at a fast rate (and continuous beeping
WALT 1 Hour Chargers, 15 Minute
E
for 15 Minute Chargers). If this occurs, re-insert battery pack. If
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 for recycling. If the
new battery pack elicits the same trouble indication as the original,
have charger tested at an authorized service center.
PROBLEM POWER LINE
If your charger has 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.
HOT PACK DELAY
If your charger has a Hot 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.
15 MINUTE CHARGERS
1. Plug the charger into an appropriate power outlet. The charger will
beep twice, the red light will blink and go off.
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 light will blink
and the charger will beep once indicating the charging process has
started.
3. The battery pack will be fully charged in less than 15 minutes under
most conditions. This will be indicated by the red light remaining ON
and 3 beeps. The pack is fully charged and may be used at this time
or left in the charger.
WEAK BATTERY PACKS: The charger 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
