MILWAUKEE LITHIUM-ION COMBO CHARGER
Charging a Hot or Cold Battery Pack
The Red Flashing Indicator light on the charger
indicates that the battery pack temperature is out-
side the charging range. Once the battery pack is
within the acceptable range, normal charging will
take place and the red light will be continuous. Hot
or cold batteries may take longer to charge.
When to Charge the Battery Pack with this
MILWAUKEE Charger
Remove the battery pack from the tool for
charging when convenient for you and your job.
MILWAUKEE batteries do not develop a "memory"
when charged after only a partial discharge. It is
not necessary to run down the battery pack before
placing it on the charger.
• Use the Fuel Gauge (on the battery pack or tool)
to determine when to charge your MILWAUKEE Li-
Ion battery pack.
• You can "Top-Off" your battery pack's charge
before starting a big job or long day of use.
• The only time it is necessary to charge the
MILWAUKEE Lithium-Ion battery pack is when the
battery pack has reached the end of its charge
How to Charge the Battery Pack
Align the battery pack with the bay and slide the
battery pack into the charger as far as possible.
The red light will come on, either quickly
(battery pack is too hot or cold), slowly
(battery pack is waiting for another pack to
charging) or continuous (pack is charging).
• A fully discharged battery pack with an internal
temperature in the normal range will charge in 30
to 75 minutes, depending on the battery pack.
• Heavily cycled batteries may take longer to charge
completely.
• The Fuel Gauge lights on 18V battery packs are
displayed as the pack is being charged, indicating
how fully charged the pack is. The fuel gauge will
turn off when charging is complete.
• After charging is complete, the continuous green
light will come on.
• The charger will keep the battery pack fully
charged if it is left on the charger.
• The second pack inserted in the charger will be-
gin charging when the pack inserted is fully
charged.

that the battery pack is fully seated into the bay.
