Charging Procedure (Fig. 1)
DANGER: Electrocution hazard. 120 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 in charger. 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, re-insert 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
FIG. 1 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
pack. Such batteries are still usable but should not be expected to
perform as much work. The charger will indicate to replace battery
pack.
