WARNING
To reduce the risk of injury 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.
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 recycling 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 fi re
or explosion.
RBRC Battery Recycling Seals
The RBRC™ Battery Recycling Seals (see
"Symbology") on your tool battery packs
indicate that MILWAUKEE has arranged
for the recycling of that battery pack with
the Rechargeable Battery Recycling Cor-
poration (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 information, visit the RBRC web site
at www.rbrc.org.
Battery Pack Protection
To protect itself from damage and extend
its life, the battery pack's intelligent circuit
will turn off the battery pack if its internal
temperature becomes too high. This could
happen in extremely high torque, binding
and stalling situations. The pack must be
placed on the charger to turn it back on.
The charger's light indicator will fl ash red,
indicating that the pack is too hot. Once the
light is continuously red, the pack has cooled
and can be used again.
Cold Weather Operation
The MILWAUKEE Lithium-Ion battery pack
can be used in temperatures down to -4°F.
When the battery pack is very cold, it may
"buzz" for the fi rst minute of use to warm itself
up. Put the battery pack on a tool and use
the tool in a light application. After about a
minute, the pack will have warmed itself up
and operate 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 cas-
ing 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, per-
manent capacity loss can result if the pack
is stored for long periods of time at high tem-
peratures (over 120° F). MILWAUKEE Lith-
ium-Ion battery packs maintain their charge
during storage longer than other battery pack
types. After about six months of storage,
charge the pack as normal.
MILWAUKEE NiCd BATTERY PACK OPERATION
Charge the new battery pack over-
night before use to allow the cells
to become fully charged. New
battery packs are not fully charged. Two
to ten normal charging/discharging cycles
may be required before the pack can take
its maximum charge.
Never completely discharge the
battery pack. MILWAUKEE battery
packs do not develop a "memory"
when charged after only a partial discharge.
Taping-on triggers or leaving work lights on
for extended periods to completely discharge
the battery pack will reduce its life by upset-
ting the electrochemical balance and can
result in short-circuiting of the battery.
MILWAUKEE battery packs will operate for many years and/or hundreds of cycles when they
are used, charged, and stored according to these instructions. Properly using, charging, and
storing your battery pack can greatly extend its life.
Do not use or charge batteries in
cold or hot places (below 41°F (5°C)
or above 113°F (45°C)). Temperature
extremes reduce the ability for battery pack
cells to hold a charge. Do not store batteries
where the temperature may exceed 120°F
(50°C), such as in a vehicle or metal building
during the summer.
To avoid overheating to a battery pack,
allow cordless tools cool down between
high torque drilling/cutting applications.
The increased energy discharge rate will
heat the battery pack cells faster than the
cells can release the heat. This could dam-
age the cells.
After use, allow a hot battery pack to cool
to room temperature before inserting it into
the charger. If a hot battery is put on a char-
ger, charging will not begin until the battery
has cooled to a safe temperature. See the
charger section of this manual for more infor-
mation on charging temperatures. Charging
a hot battery will damage the cells.
Never forcibly heat up or cool down bat-
teries. This will damage some cells in the
pack, causing them to not be able to hold
a charge.
Remove the battery pack from the tool
for charging when the tool can no longer
perform its intended function (i.e., drilling,
cutting, etc.).
After the battery pack has reached a
full charge, it will continue to receive
a trickle charge to ensure capacity is
maintained.
Occasionally (once a week) leave the
batteries on the charger overnight to help
maintain cell balance.
Do not store the battery on the charger
(for more than 24 hours); this could re-
duce battery life.
Never leave batteries on chargers where
power interruptions are common. Damage
to the battery cells could occur.
Store batteries at room tempera-
ture away from moisture. Do not
store in damp locations where corro-
sion of terminals may occur.
Do not submerge your battery or cord-
less tools in water. This will damage the
battery and tool.
Charge unused batteries overnight at
least every six months to maximize bat-
tery life. Unused batteries discharge at a
rate of about 1% per day and will be fully
discharged after six months. For batteries
stored for a long time, two to ten normal
charging cycles may be required before the
pack is fully charged.
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.
