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
