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/Cold Pack Delay mode.
