Charging Procedure

1 HOUR CHARGERS

1.Plug the charger into an appropriate power outlet.

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.

3.The battery pack will be fully charged in about 1 hour. The 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 CHARGERS

1.Plug the charger into an appropriate 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 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.

ALL CHARGERS

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 for 15 Minute Chargers). 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.

PROBLEM POWER LINE

If your charger has a Problem Power Line indicator: When the charger ‘is used with some portable power sources such as generators or sources that convert DC to AC, the charger may temporarily suspend operation, flashing the red light with two fast 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.

BATTERY PERFORMANCE

Some chargers have a tune-up feature optimizes battery pack performance. Your charger may provide Automatic Tune-Up™ Mode or manual (i.e. push button) Tune-Up™ mode. For information on this
