How to Charge the Battery Pack
Place the battery pack onto the bay by slid-
ing the pack on from the top of the bay. The
red light will come on, either fl ashing (pack
is too hot or cold) or continuous (pack is
charging).
• For
MILWAUKEE
Li-Ion battery packs,
the Fuel Gauge lights on the battery
pack are displayed as the pack is being
charged, indicating how fully charged
the pack is.
•
A fully discharged pack with an internal
temperature in the normal range* will
charge a NiCd battery pack in 45 min-
utes or less and a Li-Ion battery pack
in 60 minutes or less. Heavily cycled
battery packs may take longer to charge
completely.
*Normal Range: For Li-Ion, between
32°F and 150°F; for NiCd, between
32°F and 140°F)
•
Three battery packs can be charged
simultaneously with no change in charg-
ing times.
•
After charging is complete, the con-
tinuous green light will come on. For
MILWAUKEE
Li-Ion packs, the Fuel
Gauge lights will go off. The Fuel Gauge
button won't work when the pack is on
the charger.
•
The charger will keep the battery pack
fully charged if it is left on the charger.
•
After the battery is completely charged,
the charger will continue conditioning
("topping-off") the battery to hold a
stronger charge. Over time, batteries
begin to hold less and less charge.
The "top-off" mode helps renew the
charge-life of the battery. This process
can take from 1 to 4 hours, depending
on the battery temperature. The battery
may be removed at any point during this
cycle with no harm done.
When to Charge the Battery Pack
For MILWAUKEE NiCd Battery Packs:
Charge your battery pack overnight before
you use it for the fi rst time and then when
your tool no longer performs with the power
and torque needed for the job. Never com-
pletely discharge the battery pack.
New battery packs reach full loading capac-
ity after 2-10 chargings and dischargings.
Battery packs which have not been used
for some time should be recharged before
use.
For 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 de-
velop 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 bat-
tery 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.
Charge only MILWAUKEE 18-28V
Lithium-Ion battery packs and
MILWAUKEE 12-18V NiCd battery
packs in the MILWAUKEE Li-Ion/NiCd
Multi-Bay Battery Charger. Other
types of batteries may cause personal
injury and damage.
WARNING
CHARGER OPERATION
WARNING
To reduce the risk of injury, always
unplug the charger and remove
the battery pack from the charger
before performing any maintenance.
Never disassemble the battery pack
or charger. Contact a MILWAUKEE
service facility for ALL repairs.
To reduce the risk of injury and
damage, never immerse your battery
pack or charger in liquid or allow a
liquid to fl ow inside them.

Powering the Charger with an Inverter
or Generator
The charger will operate with most gen-
erators and inverters rated at 900 Watts or
higher. The power required is at least 300
Watts per bay.
•
If the light indicator flashes red and
green, check that the battery pack is
fully seated into the bay. Remove the
pack and reinsert. If the light continues
to fl ash red and green, the battery 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 battery pack is fully seat-
ed into the bay. Remove 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 Flashing Indicator light on the
charger indicates 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.
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.
Cleaning
Clean out dust and debris from charger vents
and electrical contacts by blowing with com-
pressed 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 combustible solvents around
battery packs, charger, or tools.
Repairs
The
MILWAUKEE
Li-Ion/NiCd charger has
no internal serviceable parts. For cordset
repairs, return the charger to the nearest
authorized service center.
