MILWAUKEE LI-ION
BATTERY PACKS
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 Lithium-
Amps
Ion battery packs maintain their charge during
3
storage longer than other battery pack types. After
3
about a year of storage, charge the pack as normal.
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.
Disposing of MILWAUKEE Lithium-Ion Batteries
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-
10
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 fi re 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 Offi ce/Service Center or the
participating retailer nearest you. For more infor-
mation, visit the RBRC web site at www.rbrc.org.
MILWAUKEE LI-ION
CHARGER
WARNING
Charge only MILWAUKEE
M12™ Lithium-Ion batteries in this MILWAUKEE
Lithium-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 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 fi nish
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 fl ashing quickly (pack
is too hot or cold), fl ashing slowly (pack is waiting
for another pack to fi nish charging) or continuous
(pack is charging).
• The 48-2659 and 48-2659A 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
temperature in the normal range will charge in 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 fl ashes red and green, check
that the pack is fully seated into the bay. Remove
the pack and reinsert. If the light continues to fl ash
red and green, the pack may be extremely hot or
cold, or wet. Allow the 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 pack is fully seated into the bay. Remove the
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
indicates that the battery pack temperature is out-
side 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 batteries may take longer to charge.

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 batteries when not in use.
No battery pack damage will occur, however, if
the charger and battery pack are left plugged in.
WARNING
To reduce the risk of injury,
always 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 fl ow inside them.
Repairs
The charger has no serviceable parts.
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
electrical 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 ammonia. Never use fl ammable or com-
bustible solvents around batteries, charger, or tools.
