MILWAUKEE LITHIUM-ION BATTERY PACK OPERATION
Fuel Gauge
Use the Fuel Gauge to determine the battery pack's
remaining run time. Press the Fuel Gauge button
to display the lights. The Fuel Gauge will stay lit
for two seconds.
Approximate Run
78-100%
Time Remaining
55-77%
33-54%
10-32%
Less than 10% if bottom light is fl ashing
NOTE: If the Fuel Gauge doesn't appear to be
working, place the battery pack on the charger and
charge as needed.
Compared to NiCd battery pack types, MILWAUKEE
Lithium-Ion battery packs deliver fade-free power
for their entire run time. The tool will not experience
a slow, gradual loss of power as you work. To signal
to you that the battery pack is at the end of its run
time and needs to be charged, power to the tool
will drop quickly. When this happens, remove the
tool from the workpiece and charge the battery
pack as needed.
NOTE: Immediately after using the battery pack,
the Fuel Gauge may display a lower charge than it
will if checked a few minutes later. The battery cells
"recover" some of their charge after resting.
Battery Pack Protection
To protect itself from damage and extend its life, the
battery pack's intelligent circuit monitors current draw
and temperature. In extremely high torque, binding,
stalling, and short circuit situations, the battery pack
will turn OFF the tool if the current draw becomes too
high. In these situations, the tool will "buzz" for about
2 seconds before it turns OFF. To prevent the tool
from turning OFF, immediately reduce pressure on
the application or release the trigger. If the tool does
turn off, release the trigger to reset. If this happens
repeatedly, the battery pack will shut down and need
to be placed on the charger to reset.
Under extreme circumstances, the internal tem-
perature of the battery could become too high. If
this happens, the battery pack will shut off. Remove
the battery pack from the tool and place it on the
charger to reset it.
To determine if the battery pack needs to be placed
on the charger to be reset, press the fuel gauge
button. If the bottom gauge fl ashes once, the bat-
tery must be reset on the charger.
Cold Weather Operation
MILWAUKEE M18 LITHIUM-ION battery packs can
be used in temperatures down to 14°F. When the
battery pack is very cold, put the battery pack on
a tool and use the tool in a light application. It may
"buzz" for a short time until it warms up. When the
buzzing stops, use the tool normally.
Maintenance and Storage
Do not expose your battery pack or cordless tools
to water or rain, or allow them to get wet. This could
damage the tool and battery pack. Do not use oil
or solvents to clean or lubricate your battery pack.
The plastic casing will become brittle and crack,
causing a risk of injury.
Store battery packs at room temperature away
from moisture. Do not store in damp locations
where corrosion of terminals may occur. As with
other battery pack types, permanent capacity
loss can result if the pack is stored for long pe-
riods of time at high temperatures (over 120° F).
MILWAUKEE Lithium-Ion battery packs maintain
their charge during storage longer than other
battery pack types. After about a year of storage,
charge the pack as normal.
Disposing of MILWAUKEE Li-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 recy-
cling agency in your area for recycling locations.
Even discharged battery packs contain some en-
ergy. Before disposing, use electrical tape to cover
the terminals to prevent the battery pack from short-
ing, which could cause a fi re or explosion.
WARNING
To reduce the risk of in-
jury or explosion, never burn or incinerate
a battery pack even if it is damaged, dead or
completely discharged. When burned, toxic
fumes and materials are created.
RBRC Battery Recycling Seals
The RBRC™ Battery Recycling Seals (see "Sym-
bology") on your tool battery packs indicate that
MILWAUKEE has arranged for the recycling of
that battery pack with the Rechargeable Battery
Recycling Corporation (RBRC). At the end of your
battery pack's useful life, return the battery pack to
a MILWAUKEE Branch Offi ce/Service Center or the
participating retailer nearest you. For more informa-
tion, visit the RBRC web site at www.rbrc.org.

CHARGER OPERATION

WARNING
Charge only MILWAUKEE
Lithium-Ion battery packs in the MILWAUKEE
Li-Ion Battery Charger. Other types of batter-
ies may cause personal injury and damage.
Battery pack and charger are not compatible
with V™-technology or NiCd systems.
To reduce the risk of electric shock, do not
allow water to fl ow into AC/DC plug.
AD/DC Charger (Cat. No. 2710-20)
To reduce the risk of damage to the charger, do
not attempt to plug into both AC and DC outlets at
the same time.
To use the AC/DC plug in a DC outlet, rotate the
DC adapter out (A) and insert into a DC outlet. The
AC plug blades should be folded in.
To use the AC/DC plug in an AC outlet, rotate the
AC plug blades out (B) and insert into an AC outlet.
The DC adapter should be folded in.

When to Charge MILWAUKEE Li-Ion Battery
Packs
Remove the battery pack from the tool for
charging when convenient for you and your job.
MILWAUKEE battery packs do not develop a
"memory" when charged after only a partial dis-
charge. 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 Lithium-Ion battery pack is when
the 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
fi nish making a cut, drilling a hole, or driving a
fastener. Charge the battery pack as needed.
How to Charge the Battery Pack
Place the battery pack onto the bay by sliding the
pack on from the top of the bay. The red light will
turn on, either fl ashing (pack is too hot or cold) or
continuous (pack is charging).
• A fully discharged pack with an internal tem-
perature between 32°F and 104°F will charge
in 30-Min or 1-Hour, depending on the battery
pack.
• Heavily cycled battery packs may take longer to
charge completely.
• The Fuel Gauge lights on the battery pack are
displayed as the pack is being charged, indicating
how fully charged the pack is.
• After charging is complete, the continuous green
light will turn on and the fuel gauge will turn off.
• The charger will keep the battery pack fully
charged if it is left on the charger.
• If the light indicator fl ashes red and green, check
that the battery pack is fully seated into the bay.
Remove the pack and 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. Re-
move the pack and reinsert. If the light indicator
still does not come on, contact a MILWAUKEE
service facility.
Charging a Hot or Cold Battery Pack
The Red fl ashing indicator light on the charger indi-
cates that the battery pack temperature is outside
the charging range. Once the pack is within the
acceptable range, normal charging will take place
and the red light will be continuous. Hot or cold
battery packs may take longer to charge.
Li-Ion Charging Status
Battery Pack Red Charger Charging Status
Temperature Indicator Light
Too Hot Flashing Not charging
Normal Range Continuous Normal charging
Too Cold Flashing Not charging
Powering the Charger with an Inverter or
Generator
The charger will operate with most generators and
inverters rated at 300 Watts or higher.
Maintenance and Storage
Store your charger in a cool, dry place.
As a general practice, it is best to unplug battery
chargers and remove battery packs when not in
use. No battery pack damage will occur, however, if
the charger and battery pack are left plugged in.
