Store your battery pack in a cool, dry place.
Do not store it where the temperature may
exceed 120°F (50°C) such as a vehicle or
metal building during the summer. High
temperatures will overheat the battery pack,
reducing battery life. If it is stored for several
months, the battery pack will gradually lose its
charge. One to three cycles of charging and
discharging through normal use will restore
the capacity of the battery pack. During the life
of the battery pack the operating time between
charges becomes shorter. If the operating
time becomes extremely short after a proper
charge, the usable life of the battery pack has
been reached and it should be replaced.
WARNING
To reduce the risk of explosion,
never burn a battery pack even if
it is damaged, dead or completely
discharged.
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.
Disposing of NiCd Battery Packs
Nickel-Cadmium battery packs are recy-
clable. Under various state and local laws, it
may be illegal to dispose of this battery into
the municipal waste stream. Dispose of your
battery pack according to federal, state and
local regulations.
MILWAUKEE NiCd BATTERY
CHARGER OPERATION
WARNING
Charge only MILWAUKEE 12, 14.4
and 18 Volt NiCd battery packs in
this charger. Other types of batteries
may explode causing personal injury
and damage.
When to charge the battery pack
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.
Standard charging times
Standard charging time is approximately
one hour. Charging time varies depending
on the battery temperature, charge needed
and the type of battery pack being charged.
For example, if the battery pack does not
require a full charge, the charging time will
be less than one hour.
Effects of temperature and vehicle volt-
age on charging
Battery packs are affected by temperature.
The charger will sense battery temperature
and will charge the battery at the most rapid
rate when its temperature is between 41°F
(5°C) and 113°F (45°C). When the battery
temperature is outside of this range, charging
will occur at a slower rate to prevent damage
to battery.

* Charge time is dependent on the vehicle's

When the vehicle engine is running, the
battery pack will charge at the highest rate.
When the vehicle is not running, its DC
system voltage is lower. If this voltage drops
below the operating limit of 11V, charging is
suspended until the voltage increases. See
the charts below for examples of typical
charge time and the effects of voltage on
charge time.
Automatic start
When a hot or cold battery pack is inserted
into the charger, charging will begin automati-
cally once the battery reaches the correct
charging temperature. When a vehicle's DC
system voltage recovers from a low voltage
condition (when the vehicle is running),
charging will begin automatically.

Maintenance charge
Batteries discharge at a rate of about 1%
per day. The Maintenance Charge feature
keeps the battery pack fully charged when
the battery pack is stored in a charger that is
plugged in. The Maintenance Charge auto-
matically begins after the battery pack is fully
charged. During Maintenance Charge,the
control light will be off.
