2. Insert the battery pack into the charger, 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 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
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.
Important Charging Notes
1. Longest life and best performance can be obtained if the battery
pack is charged when the air temperature is between 65°F and
75°F (18°–24°C). DO NOT charge the battery pack in an air
temperature below +40°F (+4.5°C), or above +105°F (+40.5°C).
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.
