Fuel Gauge

Use the Fuel Gauge to determine the battery pack's

remaining run time. Press the Fuel Gauge button

to display the lights. The Fuel Gauge will stay lit

for two seconds.

MILWAUKEE LITHIUM-ION BATTERY PACK OPERATION

Battery Pack Protection

To protect itself from damage and extend its life,

the battery pack’s intelligent circuit monitors current

draw and temperature.

In extremely high torque, binding, stalling, and short

circuit situations, the battery pack will turn OFF the

tool if the current draw becomes too high. In these

situations, the tool will "buzz" for about 2 seconds

before it turns OFF. To prevent the tool from turning

OFF, immediately reduce pressure on the applica-

tion or release the trigger. If the tool does turn off,

release the trigger to reset. If this happens repeat-

edly, the battery pack will shut down and need to

be placed on the charger to reset.

Under extreme circumstances, the internal tem-

perature of the battery could become too high. If

this happens, the battery pack will shut off. Remove

the battery pack from the tool and place it on the

charger to reset it.

To determine if the battery pack needs to be placed

on the charger to be reset, press the fuel gauge

button. If the bottom gauge ﬂ ashes once, the bat-

tery must be reset on the charger.

Cold Weather Operation

The MILWAUKEE Lithium-Ion battery pack can

be used in temperatures down to -4°F. When the

battery pack is very cold, put the battery pack on

a tool and use the tool in a light application. It may

“buzz” for a short time until it warms up. When the

buzzing stops, use the tool normally.

Approximate Run

Time Remaining

NOTE: If the Fuel Gauge doesn't appear to be

working, place the battery pack on the charger and

charge as needed.

Compared to NiCd battery pack types, MILWAUKEE

Lithium-Ion battery packs deliver fade-free power

for their entire run time. The tool will not experience

a slow, gradual loss of power as you work. To signal

to you that the battery pack is at the end of its run

time and needs to be charged, power to the tool

will drop quickly. When this happens, remove the

tool from the workpiece and charge the battery

pack as needed.

NOTE: Immediately after using the battery pack,

the Fuel Gauge may display a lower charge than it

will if checked a few minutes later. The battery cells

"recover" some of their charge after resting.

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.

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 corrosion of terminals may occur. As with

other battery pack types, permanent capacity

loss can result if the pack is stored for long pe-

riods of time at high temperatures (over 120° F).

MILWAUKEE Lithium-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.

Disposing of MILWAUKEE Lithium-Ion Battery

Packs

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 recy-

cling agency in your area for recycling locations.

Even discharged battery packs contain some en-

ergy. Before disposing, use electrical tape to cover

the terminals to prevent the battery pack from short-

ing, 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 informa-

tion, visit the RBRC web site at www.rbrc.org.

When to Charge the MILWAUKEE Li-Ion Battery

Pack

Remove the battery pack from the tool for

charging when convenient for you and your job.

MILWAUKEE battery packs do not develop a

"memory" when charged after only a partial dis-

charge. 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 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.

How to Charge the Battery Pack

Place the battery pack onto the bay by sliding the

pack on from the top of the bay. The red light will

turn on, either ﬂ ashing (pack is too hot or cold) or

continuous (pack is charging).

• A fully discharged pack with an internal tempera-

ture in the normal range will charge in between a

half-hour and an hour (between 32°F and 150°F).

Heavily cycled battery packs may take longer to

charge completely.

• The Fuel Gauge lights on the battery pack are

displayed as the pack is being charged, indicating

how fully charged the pack is.

• After charging is complete, the continuous green

light will turn on and the fuel gauge will turn off.

• The charger will keep the battery pack fully

charged if it is left on the charger.

CHARGER OPERATION

WARNING Charge only MILWAUKEE

Lithium-Ion battery packs in the MILWAUKEE

Li-Ion Battery Charger. Other types of batter-

ies may cause personal injury and damage.

Battery pack and charger are not compatible

with V™-technology or NiCd systems.
