Operation
Charging the Battery Pack
Important:
The battery pack is not fully charged
when you purchase it. Before using the tool for
the first time, place the battery pack in the charger
and charge it until the LED display indicates the
battery pack is fully charged. Read all safety
precautions.
Important:
Charge the battery pack only in
temperatures that are within the appropriate
range; refer to
Specifications (page 7)
.
Note:
At any time, press the battery-charge-indicator
button on the battery pack to display the current

If you are charging multiple battery packs,
you can switch between 2 charging modes
by pressing the A/B button on the side of the
charger:
•
Serial charging (Mode A): Fully charges 1
battery pack at a time; once fully charged,
the next battery starts charging. This results
in individual fully-charged batteries, faster.
•
Parallel charging (Mode B): All connected
battery packs are charged to the same level.
This results in all connected batteries being
evenly charged.
Note:
A battery connected to the charger may
not always be charging; if the indicator light on
the charger is yellow, that battery is on standby.
Other batteries may have priority (they are
charged first due to their state of charge or the
charging mode selected); once other batteries
have charged to the necessary level, the battery
on standby begins to charge.
5.
To remove the battery pack, slide the battery
backward out of the charger.
