completion of charge will be indicated by the red light remaining ON
continuously. The pack is fully charged and may be used at this time
or left in the charger.
15 MINUTE CHARGER
1. Plug the charger into an appropriate AC power outlet. The charger
will beep twice, the red light will blink and go off.
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 light will blink
and the charger will beep once indicating the charging process has
started.
3. The battery pack will be fully charged in less than 15 min. 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.
Leaving the battery pack in the charger: When the red light remains
ON, the charger has switched to its "equalize charge" mode which
lasts approximately 4 hours, after which the charger will switch to
"maintenance charge" mode. The battery pack can be removed at
any time during these charge cycles, but will only be fully charged if the
red light is continuously ON. 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. A battery pack will slowly lose
its charge when kept out of the charger. If the battery pack has not
been kept on maintenance charge, it may need to be recharged before
use. A battery pack may also slowly lose its charge if left in a charger
that is not plugged into an appropriate AC source.
Trouble Indicators: These chargers are designed to detect certain
problems that can arise with battery packs which would be indicated by
the red light flashing at a fast rate and continuous beeping. If this
occurs, re-insert battery pack. If 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 for recycling. If the new battery pack elicits the same
trouble indication as the original, have charger tested at an authorized
service center.
Weak Battery Packs: (15 Minute Charger). 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.
