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 charg-
er is OK. If the new pack charges correctly, then the original pack is
defective and should be returned to a service center or other collec-
tion 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 charg-
er 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
