1 HOUR CHARGERS

2. Insert the battery pack into the charger, as shown in FIG.1,
making sure the pack is fully seated in the charger. The red
(charging) light will blink continuously indicating that the
charging process has started.

blinks followed by a pause. This indicates the power source is out
of limits.
HOT PACK DELAY
If your charger has a Hot 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.

process has started.
3. The battery pack will be fully charged in less than 15 minutes
under most conditions. This will be indicated by the red light
remaining ON and 3 beeps. The pack is fully charged and may
be used at this time or left in the charger.
WEAK BATTERY PACKS: The charger can also detect a weak
battery. Such batteries are still usable but should not be expected
to perform as much work. In such cases, about 10 seconds after
battery insertion, the charger will beep rapidly 8 times to indicate a
weak battery condition. The charger will then go on to charge the
battery to the highest capacity possible.
