MILWAUKEE LI-ION
COMBO CHARGER
WARNING
Charge only MILWAUKEE 12 and
18V Li-Ion batteries in the
MILWAUKEE 12 and 18V Li-Ion Combo Charger.
Other types of batteries may cause personal in
-
jury and damage.
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 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 Li-Ion battery pack is when the battery
pack has reached the end of its charge. To signal
the end of charge, power to the tool will drop quickly,
allowing you just enough power to finish making a
cut, drilling a hole, or driving a fastener. Charge the
battery pack as needed.
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 flashing quickly (bat
-
tery pack is too hot or cold), flashing slowly (battery
pack is waiting for another pack to finish charging)
or continuous (pack is charging).
• A fully discharged battery pack with an internal tem
-
perature in the normal range will charge in about 30
to 185 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 light indicator will flash
green during this maintenance charging.
• The second pack inserted in the charger will begin
charging when the first pack inserted is fully charged.
• If the light indicator flashes red and green, check that
the battery pack is fully seated into the bay. Remove
the battery pack and reinsert. If the light continues
to flash red and green, the battery pack may be ex
-
tremely hot or cold, or wet. Allow the battery pack to
cool down, warm up, or dry out and then reinsert. If
the problem persists, contact a MILWAUKEE service
facility.
• If the light indicator does not come on, check that
the battery pack is fully seated into the bay. Remove
the battery pack and reinsert. If the light indicator
still does not come on, remove pack(s) and unplug
charger for at least 2 minutes. After 2 minutes,
plug charger back in and insert pack. If after these
attempts the light indicator still does not come on,
contact a MILWAUKEE service facility.
Charging a Hot or Cold Battery Pack
The Red Flashing Indicator light on the charger in
-
dicates that the battery pack temperature is outside
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 bat-
teries may take longer to charge.
