Charging Battery Pack

(1 Hour Charger)

Plug charger cord into your standard power outlet. Before inserting battery pack 1, remove protective cap 2, then insert battery pack 1 into charger 3. The charger’s green indicator 4 will begin to “BLINK”. This indicates that the battery is receiving a fast charge. Fast-charging will automatically stop when the battery pack is fully charged.

When the indicator light stops “BLINKING” (and becomes a steady green light) fast charging is complete.

When you begin the charging process of the battery pack, a steady green light could also mean the battery pack is too hot or too cold.

The purpose of the light is to indicate that the battery pack is fast-charging. It does not indicate the exact point of full charge. The light will stop blinking in less time if the battery pack was not completely discharged.

When the battery pack is fully charged, unplug the charger (unless you're charging another battery pack) and slip the battery pack back into the tool handle (Fig. 35).

To prevent fire or injury when batteries are not in tool or charger, always place protective cap onto end of battery pack.

Important Charging Notes

1.The battery pack accepts only about 80% of its maximum capacity with its first few charge cycles. However, after the first few charge cycles, the battery will charge to full capacity.

2.The charger was designed to fast charge the battery only when the battery temperature is between 40˚F (4˚C) and 105˚F (41˚C).

3.A substantial drop in operating time per charge may mean that the battery pack is nearing the end of its life and should be replaced.

4.If you anticipate long periods (i.e. a month or more) of non-use of your tool, it is best to run your tool down until it is fully discharged before storing your battery pack. After a long period of storage, the capacity at first recharge will be lower. Normal capacity will be restored in two or three charge/discharge cycles. Remember to unplug charger during storage period.

5.If battery does not charge properly:

a.Check for voltage at outlet by plugging in some other electrical device.

b.Check to see if outlet is connected to a light switch which turns power “off” when lights are turned off.

c.Check battery pack terminals for dirt. Clean with cotton swab and alcohol if necessary.

d.If you still do not get proper charging, take or send tool, battery pack and charger to your local Bosch Service Center. See “Tools, Electric” in the Yellow Pages for names and addresses.

Note: Use of chargers or battery packs not sold by Bosch may void the warranty.
