Charger Indicators, symbols and meaning (model BC1836)
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.
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.
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. 3).
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 will stop blinking in less time if the battery
pack was not completely discharged.
When you begin the charging process of the
battery pack, a steady red light could also
mean the battery pack is too hot or too cold.
Fast charging is only possible when the
temperature range of the battery pack is
between 32˚F (0˚C) and 113˚F (45˚C). When
needed, the internal fan of the charger will turn
on to aid the charging process and speed.
As soon as the battery pack reaches the
correct temperature range, the battery charger
will automatically switch to fast charging.
If the red indicator light is “BLINKING”, the
battery pack cannot accept a charge.
• Check to make sure the battery pack is
inserted into the charger properly.
• Clean the contacts of the charger or battery
pack (e. g. by inserting and removing the
battery several times) or replace the battery
pack, as required.
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.
