Disposing of MILWAUKEE Lithium-Ion
Battery Packs
MILWAUKEE Lithium-Ion battery packs are more
environmentally friendly than some other types of
power tool battery packs (e.g., nickel-cadmium).
Always dispose of your battery pack according to
federal, state and local regulations. Contact a re-
cycling agency in your area for recycling locations.
Even discharged battery packs contain some energy.
Before disposing, use electrical tape to cover the
terminals to prevent the battery pack from shorting,
which could cause a fire or explosion.

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 Lithium-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. 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
temperature in the normal range will charge in 30
to 185 minutes, depending on the battery pack.
• 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 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, remove pack(s)
and unplug charger for at least 2 minutes. After 2
minutes, plug charger back in and insert pack. 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 min-
utes. After 2 minutes, plug charger back in and
insert pack. If 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.

Maintenance and Storage
Store your charger in a cool, dry place.
As a general practice, it is best to unplug battery
chargers and remove batteries when not in use.
No battery pack damage will occur, however, if the
charger and battery pack are left plugged in.
To reduce the risk of injury, always
WARNING
unplug the charger and remove the
battery from the charger before performing any
maintenance. Never disassemble the battery or
charger. Contact a MILWAUKEE service facility
for ALL repairs.
To reduce the risk of injury and damage, never
immerse your battery or charger in liquid or allow
a liquid to flow inside them.
Cleaning
Clean out dust and debris from charger vents and
electrical contacts by blowing with compressed air.
Use only mild soap and a damp cloth to clean the
battery pack and charger, keeping away from all elec-
trical contacts. Certain cleaning agents and solvents
are harmful to plastics and other insulated parts.
Some of these include gasoline, turpentine, lacquer
thinner, paint thinner, chlorinated cleaning solvents,
ammonia and household detergents containing am-
monia. Never use flammable or combustible solvents
around batteries, charger, or tools.
The charger has no serviceable parts.
