The automatic refresh mode will equalize or balance

light will stay on continuously and will no longer
blink. The battery pack is fully charged and can be
used at this time.
If the battery pack is left in the charger after the initial
1-hour charge, the charger will automatically initiate
the refresh mode. This mode will continue up to
8 hours, but the battery pack can be removed at
any time during the refresh mode.

hot or too cold, it automatically starts a Hot/Cold
Pack Delay, suspending charging until the battery
has reached an appropriate temperature. The
charger then automatically switches to the pack
