14. DO NOT SHORT CIRCUIT. A battery
pack will short circuit if a metal object
makes a connection between the posi-
tive and negative contacts on the battery
pack. Do not place a battery pack near
anything that may cause a short circuit,
such as coins or keys in your pocket. A
short circuited battery pack may cause
fi re and personal injury.

15. STORE YOUR BATTERY PACK AND
CHARGER in a cool, dry place. Do not
store battery pack where temperatures
may exceed 120°F (50°C) such as in
a vehicle or metal building during the
summer. Charger will charge the battery
when the temperature is between 41°F
(5°C) and 113°F (45°C). When the bat-
tery temperature is outside that range,
charging will not occur.

MILWAUKEE NiCd BATTERY PACK OPERATION
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.
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.
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.
Maintenance and Storage
MILWAUKEE battery packs will operate for
many years and/or hundreds of cycles when
they are maintained and used according to
these instructions.
A battery pack that is stored for six months
without being used will discharge itself.
Charge the battery every six months even if
it is unused to maximize battery life. Do not
tape the trigger in the "ON" position and leave
the tool unattended as this may discharge
the battery to a point where it will no longer
be able to recharge. Use a MILWAUKEE
battery pack only until it no longer performs
with the power and torque needed for your
application.
