MILWAUKEE LI-ION
BATTERY PACKS
To reduce the risk of fire, personal
WARNING
injury, and product damage due to
a short circuit, never immerse your tool, battery
pack or charger in fluid or allow a fluid to flow
inside them. Corrosive or conductive fluids, such
as seawater, certain industrial chemicals, and
bleach or bleach containing products, etc., can
cause a short circuit.
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 cor-
rosion of terminals may occur. As with other battery
pack types, permanent capacity loss can result if
the pack is stored for long periods of time at high
temperatures (over 120° F). MILWAUKEE Li-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.
To reduce the risk of injury or ex-
WARNING
plosion, never burn or incinerate a
battery pack even if it is damaged, dead or com-
pletely discharged. When burned, toxic fumes
and materials are created.
Disposing of MILWAUKEE Li-Ion
Battery Packs
MILWAUKEE Li-Ion battery packs are more environ-
mentally 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 fire or explosion.
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 Office/Service Center or the
participating retailer nearest you. For more informa-
tion, visit the RBRC web site at www.rbrc.org.
MILWAUKEE LI-ION
CHARGER
Charge only MILWAUKEE M12™
WARNING
Li-Ion batteries in this MILWAUKEE
Li-Ion charger. Other types of batteries may cause
personal injury 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).
• The 48-59-1204 charges four battery packs, in
sequence, from left to right.
•The next pack inserted in the charger will begin
charging when the previous pack is fully charged.
To skip a pack and move on to the next, press the
skip button .
• A fully discharged battery pack with an internal tem-
perature in the normal range will charge in about 30
to 90 minutes, depending on the battery pack.
• Heavily cycled batteries may take longer to charge
completely.
• After charging is complete, the continuous green
light will come on.
• 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 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.
