1. The charger was designed to fast charge
the battery only when the battery temperature
is between 32˚F (0˚C) and 113˚F (45˚C). If the
battery pack is too hot or too cold, the charger
will not fast charge the battery. (This may
happen if the battery pack is hot from heavy
use). When the battery temperature returns to
between 32˚F (0˚C) and 113˚F (45˚C), the
charger will automatically begin charging.
2. 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.
3. Remember to unplug charger during storage
period.
CHARGER INDICATORS, SyMBOLS AND MEANING (Model BC630)
If the indicator lights are "OFF", the charger is
not receiving power from power supply outlet.
If the green indicator light is "ON",
the charger is plugged in but the
battery pack is not inserted, or
the battery pack is fully charged.
If the green indicator light is
"BLINKING", the battery pack is
being fast-charged. Fast-charging
will automatically stop when the battery pack is
fully charged.
Plug charger cord into your standard power
outlet.
With no battery pack inserted, the charger's
green indicator light will go ON. This indicates
the charger is receiving power and the charger
is ready for operation.
When you insert the battery pack into the
charger. The charger's green indicator light will
begin to "BLINK". This indicates that the battery
is receiving a fast charge (Fig. 11).

4. 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 will void the warranty.
If the red indicator light is "ON",
the battery pack is too hot or cold
for fast-charging. The charger will
automatically switch to fast-charging once a
suitable temperature is reached.
If the red indicator light is
"BLINKING", the battery pack
cannot accept a charge or the
contacts of the charger or battery pack are
contaminated. Clean the contacts of the
charger or battery pack only as directed in
these operating instructions or those supplied
with your tool or battery pack.
When the indicator light stops "BLINKING" (and
becomes a steady green light) fast charging is
complete. The battery pack is fully charged and
can be removed from the charger.
The battery pack may be used even though the
light may still be blinking. The light may require
more time to stop blinking depending on
temperature.
The purpose of the green light is to indicate that
the battery pack is fast-charging. It does not
indicate the exact point of full charge. The light
